Answer:
His weekly exercise time goal is 168 minutes.
Step-by-step explanation:
This question can be solved using a rule of three.
42 minutes is 25% = 0.25 of the total
x minutes is 100% = 1 of the total.
Then
42 minutes - 0.25
x minutes - 1
![0.25x = 42](https://tex.z-dn.net/?f=0.25x%20%3D%2042)
![x = \frac{42}{0.25}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B42%7D%7B0.25%7D)
![x = 168](https://tex.z-dn.net/?f=x%20%3D%20%20168)
His weekly exercise time goal is 168 minutes.
A fact or piece of data from a study of a large quantity of numerical data
Answer:
x- intercept (7, 0) , (3,0)
Step-by-step explanation:
there is the answer of x intercept
0=x^2-10x+21
= (x-7)(x-3)
x= 7 and 3
2x + 4 because she is playing 2 times as much as trent which is where the 2x come in and also 4 more hours than kailey which is the +4
The equation is on y and x. We need to prove X+Y=100
Step-by-step explanation:
If the value of X=40,
Then value of Y could be 100-40 because the total count is 100.
Y=60.
Verification done by the given equation.
X+Y=100
Y=100-X
Y=100-40
Y=60
Therefore the value of the Y is 60
