Step-by-step explanation:
x= children
y= adult
First equation: x+y= 2900
Second equation: 1.50x + 4y= 6100
From first equation: x+y= 2900
x= 2900-y, becomes the third equation
Second equation: 1.50(2900-y) + 4y= 6100
4350-1.50y+ 4y= 6100
2.5y = 1750
y= 700
700 adults
Thrid equation: x= 2900-700
= 2200
2200 children
So total have 700 adults and 2200 children

How do you explain a diameter of 0.00085 inches using scientific notation
Answer:
8.5 [tex]E^{-4}[/tex] inches
Step-by-step explanation:
Scientific scientific notation is where the super small / super large number is multiplied by a 10 (E) to the power of a number. Here, the number is smaller than 8.5 so our power must be negative. As we are making it four "places" bigger, we use the exponent of -4.

Line QS is a perpendicular bisector to triangle PQR as pictured below.
What is the length of the value of x?
I need an answer ASAP
Answer:
3
Step-by-step explanation:
Side QP is equal to side QR so 4x-2=10, then just solve for x and you get 3
Answer:
x=3
Step-by-step explanation:
the trangal is isosoles so both sides need to equal 10 so the equation would be 4x-2=10.
frist you would add both sides by 2
4x-2=10
+2 +2
4x=12
then you would divide both sides by 4
4x/4=12/4
so your anser should be x=3

What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (2, 1) and (0, 3).
Now,
Since, The equation of line passes through the points (2, 1) and (0, 3).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (3 - 1)) / (0 - 2)
m = 2 / - 2
m = - 1
Thus, The equation of line with slope - 1 is,
⇒ y - 1 = - 1 (x - 2)
⇒ y - 1 = - x + 2
⇒ y = - x + 2 + 1
⇒ y = - x + 3
Therefore, The general form of the equation of the line shown is,
⇒ y = - x + 3

Cells Are Us charges $5 per month and $1.50 per minute on their prepaid plan. The total cost for a cell bill can be represented by the equation C = 1.5m + 5, where m represents the number of minutes and C represents the cost, in dollars. Call Time charges $15 per month and $0.50 per minute on their prepaid plan.

Ashton had $60 to take shopping with her. She bought a dress for $16.50, a pair of shoes for $12.25, and 3 head bands for $2.25 each. She paid a 6% sales tax on all of the items she bought. How much money did Ashton have left?
Answer:
$22.37
Step-by-step explanation:
[Total Cost] 16.5 + 12.25 + (3)2.25 = $35.50
[Sales Tax] 6% -> 0.06
35.5 * 0.06 = 2.13
35.5 + 2.13 = $37.63

Rosa can run 4 miles in 56 minutes. How many kilometers does Rosa run if she runs for 42 minutes?
Answer:
First, let’s use what we know to determine how many miles Rosa can run in a minute.
We do so by dividing 4 by 56 (4/56), which equals .071, after rounding.
So, Rosa runs .071 miles in a minute. Now we multiply this by 42 to get our final answer.
42 x .071 = 2.98. Using rounding, we know that Rosa can run 3 miles in 42 minutes.

Answer:y=-1/2x-3
Step-by-step explanation:
write an equation in slope-intercept form of the line shown (1,-9) , (-3,-9)
Answer:
y = -9
Step-by-step explanation:
y2 - y1 / x2 - x1
-9 - (-9) / -3 - 1
0 / -4
y = 0 + b
-9 = b
Answer:
[tex]\boxed{\sf{y=-9}}[/tex]Step-by-step explanation:
The slope-intercept form is the only way to solve this problem.
Slope-intercept form:
[tex]\rightarrow \sf{y=mx+b}[/tex]
The m represents the slope.The b represents the y-intercept.Using the slope is another way to solve.
(1,-9) and (-3,-9)Use a slope formula.
Slope:
[tex]\sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{rise}{run} }[/tex]
y2= (-9)
y1= (-9)
x2= (-3)
x1= (1)
Rewrite the problem.
[tex]\sf{\dfrac{(-9)-(-9)}{(-3)-1}=\dfrac{0}{-4}=\boxed{\sf{0} }[/tex]
Therefore, the slope is 0.We're not done yet.
y-intercept= (-9).
The m represents is 0.
The b represents is (-9).
So, the correct answer is y=-9.I hope this helps you! Let me know if my answer is wrong or not.

Answer:
ADE = 63°
Step-by-step explanation:
One thing at a time. We can start telling that triangle ADE is isosceles, of baseAD. Means the two angles EAD e ADE are congruent, and each measures [tex]\frac {180-54}2 = 63°[/tex].
Now look at angles EDA and ECB. They are corresponding angles relative to the parallels DA and CB, so they are congruent. Measure of angle C is the same of measure of angle ADE = 63°
Edit: I've been asked for the rest of the measures. Purple ones are the one you find during the exercize. Red ones are the remaining. External ADC is supplementary to ADC (it's an external angle) angle BAD is alternate to ADE respect to the two parallels AB and CE, so they are congruent. Angle ABC is supplementary to angle BCD since they're internal conjugate relative to the same two parallels.
The carnival fundraiser at Westville Elementary School raised $300 on Friday. On Saturday, the carnival will raise 480 percent of that amount. Which statements are true about the amount of money that the carnival will raise on Saturday? Check all that apply.
The answer will be less than $300 because 100 is less than 480.
The answer will be greater than $300 because 480 is greater than 100.
(100)(3) = 300, so 480(3) is the amount of money that the carnival will raise on Saturday.
480 + 300 is the amount of money that the carnival raised on Saturday.
The carnival raised $780 on Saturday.
The carnival raised $1,440 on Saturday. its mulaple choice

given the equation y+9=-3(x-4) what point does the line pass through?
Answer:
(0,-5)
Step-by-step explanation:
First you want to simplify this equation by distributing the 3 into x-4:
y+9 = -3x+4
Next subtract 9 from both sides:
y= -3x -5
Now since I am assuming you want the Y-Intercept because you didn't ask for a specific point then it passes through the Y axis at the point (0,-5)

Graph the line with the equation y = 4/5x + 2
Answer: I have provided a screenshot of what your graph should look like so uh yeah you got this!
The graph of the line with the equation y = 4/5x + 2 is given in below attachment.
To graph the line with the equation y = (4/5)x + 2, we can use the slope-intercept form, which is y = mx + b.
where "m" represents the slope and "b" represents the y-intercept.
In this case, the slope (m) is 4/5, and the y-intercept (b) is 2.
To plot the line, we can start by plotting the y-intercept, which is the point (0, 2).
From there, we can use the slope to find additional points and connect them to form the line.
Let's plot a few more points:
When x = 5:
y = (4/5)(5) + 2
= 4 + 2 = 6
So we have the point (5, 6).
When x = -5:
y = (4/5)(-5) + 2
= -4 + 2
= -2
So we have the point (-5, -2).
