The first step in solving 3+7(x-5)=2x+16 is to
Multiply out the things in the brackets.
3+7(x+5)=2x+16
3+7x+35=2x+16
Bring the x's over to one side and the numbers to the other side.
7x-2x=16-35-3

In the study of pesticide use and breast cancer, researchers evaluated pesticide use during the entire life of the respondents. How would you expect the results to have been affected if the researchers collected exposure history spanning the previous 20 years only?
Answer:
Kindly check explanation
Step-by-step explanation:
A common problem with most research designs is bias, which could be introduced win several ways one if which is the favored selection of certain variables rather than being randomized. In the scenario above, the sampling time frame introduces a bias into the design as the tune span of pesticide use does not allay with that of the exposure history of the respondent. Therefore an entire lifetime evaluation of one variable and just 20 years evaluation of the other introduces a sampling bias into the research design. Similarly, evaluation the type of pesticide usage over certain time period may need to be considered as the effect of very old pesticides may differ from those used very recently.

Ashley practiced the piano for 41 minutes. She practiced 13 minutes less than(means subtraction) her brother did. Write and solve an equation to determine how long her brother practiced the piano.(identify the question)
Answer:
b-13=41
Step-by-step explanation:
Let b stand for the total number of minutes he practiced for. Subtracting 13 from it gets us Ashley's 41, so the equation can be b-13=41.
an eagle flew 20 m above sea level.A fish was 35 m vertically below the eagle. find the position of the fish
Answer:
15m below sea level
Step-by-step explanation:
Given data
Distance of eagle from sea= 20m
Distance of fish from eagle = 35m
Required
The distance of the fish from below the sea level
= 35-20
= 15m
Hence the fish is 15m below sea level
Write an recursive formula for a_n and the n^th term of the sequence 3, -18, 108, If You answer this, you might become Brainliest
Answer:
an=a1+(n-1)*-6
Step-by-step explanation:
a1= 3
the recursive formula is an= a1+ (n-1)d
d= how you get from one to the other
to get from 3 to -18 you could either subtract 21 or multiply it by -6
to find which one you have to look at the next number which is 108
to get from -18 to 108 you would either add 126 or multiply it by -6
since multiplying by -6 is in both that is the answer
d= -6
an=a1+(n-1)*-6

solve the proportion X-16/x+6 = 3/5
Answer:
x = 49
Step-by-step explanation:
Given
[tex]\frac{x-16}{x+6}[/tex] = [tex]\frac{3}{5}[/tex] ( cross- multiply )
5(x - 16) = 3(x + 6) ← distribute parenthesis on both sides
5x - 80 = 3x + 18 ( subtract 3x from both sides )
2x - 80 = 18 ( add 80 to both sides )
2x = 98 ( divide both sides by 2 )
x = 49
Answer:
x = - 49
Step-by-step explanation:
Solve for X by cross multiplying.

Sally measured the height of a flower growing in her garden. The flower was 3.25 inches tall. Over the next week, the flower grew h inches and measured 4.125 inches tall. How many inches did the flower grow during the week? Round to the nearest hundredth.
Answer: The flower grew 0.88 inches during the week
Step-by-step explanation:
Height of flower in the previous week = 3.25 inches
Height of flower the next week = 4.125inches
height the flower added during the week = 4.125 inches - 3.25inches
=0.875 inches
Rounding to the nearest hundredths becomes 0.88 inches
An inlet pipe can fill a water tank in 12 hours. An outlet pipe can drain
the tank in 20 hours. If both pipes are mistakenly left open, how long will
it take to fill the tank?
============================================================
Explanation:
Let's consider the tank's full capacity is 240 gallons. I'm picking this number because 12*20 = 240.
If the tank is 240 gallons, then the inlet pipe can fill it at a rate of 240/12 = 20 gallons per hour. Note after 12 hours, we have 12*20 = 240 gallons filled assuming the outlet pipe is sealed shut.
At the same time, the outlet pipe is draining at a rate of 240/20 = 12 gallons per hour. After 20 hours, the outlet pipe would drain out 12*20 = 240 gallons assuming the inlet pipe is not adding any water.
With the two pipes playing this tug-of-war battle, the inlet pipe ultimately wins because it's adding more gallons of water each hour, compared to the amount drained per hour. The net change is +20-12 = 8 gallons per hour.
This means it will take 240/8 = 30 hours to fill the tank with both pipes open.
----------------------------------
Another approach:
The inlet pipe can fill the tank in 12 hours, so it gets 1/12 of the job done per hour. The outlet pipe drains the tank in 20 hours, so it gets 1/20 of the job done in one hour.
The net change is 1/12 - 1/20 = 5/60 - 3/60 = 2/60 = 1/30
This means that when both pipes are open, 1/30 of the job is done per hour. By "job", I mean "filling the tank".
If x is the number of hours needed to do one full job, then we can multiply that by the unit rate (1/30) and set the result equal to 1
(rate)*(time) = 1 job
(1/30)*x = 1
x = 30*1
x = 30
It takes 30 hours to do the job with both pipes open.
what’s the slope_____
Answer:
-4
Step-by-step explanation:
The formula for finding the slope of a line is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] when the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. We can take any two points given to us from the table and plug them into that expression. For example, we can use the points (0,0) and (2,-8).
[tex]\frac{y_2-y_1}{x_2-x_1}\\= \frac{-8-0}{2-0}\\= \frac{-8}{2}[/tex]
Simplify the fraction
[tex]= -4[/tex]
Therefore, the slope of the line is equal to -4.

Express as a trinomial. (x+3)(3x-1)
Answer:
3x^2+8x-3
Step-by-step explanation:
(x+3)(3x-1)
x*3x + x*(-1) + 3x*3 + 3*(-1)
x*3x = 3x^2
x*(-1) + 3x*3 = -x+9x = 8x
3*(-1) = -3
= 3x^2+8x-3
The expression for the trinomial ( x + 3 ) ( 3x - 1 ) is [tex]3x^{2} + 8x - 3[/tex]
Given data:
The expression is represented as (x + 3)(3x - 1)
To express the product of (x + 3)(3x - 1) as a trinomial, perform the multiplication.
Using the FOIL method (First, Outer, Inner, Last), we multiply the terms:
(x + 3)(3x - 1) = x(3x) + x(-1) + 3(3x) + 3(-1)
Simplifying further:
[tex]3x^{2} - x + 9x - 3[/tex]
Combining like terms:
[tex]3x^{2} + 8x - 3[/tex]
Hence, the expression (x + 3)(3x - 1) can be expressed as the trinomial [tex]3x^{2} + 8x - 3[/tex] .

[tex]Which point is closer to the line y=1/2x+4, A(-2,6) or B (4,3)?[/tex]
9514 1404 393
Answer:
neither; they are the same distance from the line
Step-by-step explanation:
The distance of point (x, y) from line ax+by+c=0 is given by ...
d = |ax +by +c|/(√a² +b²)
Since we're using the same line for both points, we only need to evaluate ...
d = |ax +by +c|
Subtracting y can put the equation in the desired form:
1/2x -y +4 = 0
__
For point A, the expression of interest evaluates to ...
|(1/2)(-2) -(6) +4| = |-1-6+4| = 3
For point B, the expression of interest evaluates to ...
|(1/2)(4) -(3) +4| = |2-3+4| = 3
These values tell us the points are the same distance from the line.
_____
The attached graph shows that circles of the same radius centered on A and B are both tangent to the line. Hence the distances are the same.
There are 4 red balls in a bag and an unknown number of white balls. If we randomly
choose a ball from the bag, the probability of getting a white ball is larger than the
probability of getting a red ball. What might be the number of white balls in the bag?
Step-by-step explanation:
well if there were 5 white the probability is 5/9 vs 4/9 for red. so the number of white balls is anything greater than or equal to 5
When the angle of elevation to the sun is 42 a flagpole casts a shadow that is 21 ft long. What is the height of the flagpole to the nearest foot?
Answer:
18.91 cm
Step-by-step explanation:
Let x represent the height of the flag pole
Tan= opposite/ adjacent
Tan 42°= x/21
x= Tan 42° × 21
= 0.9004 × 21
= 18.91 cm
Hence the height is 18.91 cm
