2. Nick and Adam workout together. Nick weighs
160 pounds and is gaining about 3 pounds per
week. Adam weighs 195 pounds and is los ng
about 2 pounds each week. Write an equation
that can be used to find the number of weeks
that it will take them to weigh the same amount.
a. Equation:
b. Solution:
c. How much will Nick and Adam weigh?
Answers
Answer:
Equation: 160 + 3x = 195 - 2x
Solution: 7 weeks
Step-by-step explanation:
x is going to stand for the number of weeks
Nick:
160 + 3x
Adam:
195 - 2x
Equation: 160 + 3x = 195 - 2x
Solution: 7
They would weigh 181 pounds
The equation to find when Nick and Adam will weigh the same amount is
160 + 3w = 195 - 2w
It will take 7 weeks for Nick and Adam to weigh the same amount.
After 7 weeks, Nick and Adam will both weigh 181 pounds.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
a.
Let w be the number of weeks, then the equation to find when Nick and Adam will weigh the same amount is:
160 + 3w = 195 - 2w
b.
To solve for w, we can simplify the equation:
160 + 3w = 195 - 2w
5w = 35
w = 7
c.
To find how much Nick and Adam will weigh after 7 weeks, we can plug w = 7 into either of the original equations:
Nick's weight = 160 + 3w = 160 + 3(7) = 181 pounds
Adam's weight = 195 - 2w = 195 - 2(7) = 181 pounds
Thus,
The equation to find when Nick and Adam will weigh the same amount is
160 + 3w = 195 - 2w
It will take 7 weeks for Nick and Adam to weigh the same amount.
After 7 weeks, Nick and Adam will both weigh 181 pounds.

The operation is division.

The variable is the number of bags.
342 divided by 6 equals 57.
Write the division expression as a fraction, StartFraction p Over 6 EndFraction.
To evaluate, substitute 342 for the variable.
Each bag will have 57 peanuts.
The constant is 342.
Answers
Answer:
Step-by-step explanation:
6 P = 342
To solve the question, you need to divide by 6
You don't multiply
The operation is division
The variable is the number of peanuts in each bag.
The answer is 57
The last two are incorrect.
x/p // 6 / end fraction
start fraction /p * end fraction /6
This doesn't make an awful lot of sense to me. But it is also untrue.
The variable P will never take 342

Monday
The sale price of the items was $41.40
Mrs. Bolden paid $2.48 in sales tax on her purchase.
Altogether, Mrs. Bolden paid $43.88 for the shirts and flip flops.
Tuesday
The price decreased by approximately 8%
3.44 ÷ 3.75 = 0.917
0.917 × 100 = 91.7
91.7 ≈ 92
100 - 92 = 8
8% of 3.75 is 0.3
3.75 - 0.3 = 3.45
3.45 ≈ 3.44

4 1/4 = 4.25
91.5 ÷ 4.25 = 21.5294117647
21.5294117647 × 4.25 = 91.5
21.5294117647 ≈ 21 ¹/₂ yrs

If she marked up the price by 40%, that means $15 is 60% the original/selling price.

The selling price is $25
If you wanted to confirm, 0.6 × 25 = 15

How do you find exact values?
Answers
Answer:
Using trigonometric identities: A trigonometric identity is a relationship between trigonometric functions that we can use to find an exact value of a trigonmetric function.Using the unit circle: The unit circle is a circle with its center at the origin and a radius of 1 unit. If we place an angle, θ, with its initial side along the positive x-axis, then the point where the angle's terminal side intersects the unit circle is (cos(θ), sin(θ)).Using reference angles: Reference angles are the smallest angle that the terminal side of an angle makes with the x-axis. As it turns out, trigonometric functions of an angle and its reference angle have the same value, except that they may have different signs.
For example, suppose we want to find the exact value of tan(405°). First, we take a look at the angle 405° on a graph with the unit circle:
in this that the reference angle of 405° is 45°. We can use the fact that tangent is positive in the first quadrant and the rule for reference angles to deduce that tan(405°) = tan(45°). Then we can use the well-known fact that tan(45°) = 1 to get that tan(405°) = 1.

Answers
Answer:
232 miles had travelled when Houa fell asleep.
Step-by-step explanation:
1. .29 x 800 = 232
If the total length of the trip was 800 miles then 232 miles had they travelled when Houa fell asleep.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that Houa's family took a road trip to the Grand Canyon.
Houa fell asleep 29% of the way through the trip.
If the total length of the trip was 800 mile we need to find the number of miles they travelled when Houa fell asleep.
29% can be converted to decimal by dividing with 100
29/100=0.29
Now multiply 0.29 with 800
0.29×800
232 miles
Hence, 232 miles had they travelled when Houa fell asleep.

Determine if the following ratios form proportions.

2.) 3 to 4 and 24 to 18
3.)1:5 and 6:30
for brainiest:)
Answers
Answer:
1. Proportional
2. Not proportional
3. Proportional
Step-by-step explanation:
We have three questions with 2 ratios and are asked if they are proportional or not.
To define proportionality, basically its if the two ratios equal the same value when put in a certain way.
And that way is :
[tex]\frac{x}{y} =\frac{x}{y}[/tex]
You will substitute the numbers with the letters, in which you will cross multiply :
[tex]\frac{x * y}{x*y}[/tex]
So subtitute :
1.
[tex]\frac{1}{3} *\frac{7}{21}[/tex]
[tex]\frac{1*21}{7*3}[/tex]
[tex]21=21[/tex]
Therefore 1. is proportional.
2.
[tex]\frac{3}{4} *\frac{24}{18}[/tex]
[tex]\frac{4*24}{3*18}[/tex]
[tex]\frac{96}{54}[/tex]
96 = 54
Therefore 2. is not proportional.
3.
[tex]\frac{1}{5} *\frac{6}{30}[/tex]
[tex]\frac{1*30}{5*6}[/tex]
[tex]\frac{30}{30}[/tex]
30 = 30
Therefore 3. is proportional.

the price of a ring was decreased by 25% to £390. what was the price before the decrease?
Answers
Answer:
The original price was 520
Step-by-step explanation:
To find this, we first need to note that we paid 75% of the price. This is because we took 25% off from the original. Now we take the price we paid and divide it by the percentage of it which we paid. This will give us the original price.
390/75% = Total
390/.75 = Total
520 = Total
