X can be 7 and y can be 1 or vise versa
Answer:
y=-3
y=6
y=15
y=24
y=32
Step-by-step explanation:
Replace x with the numbers
Remember PEMDAS(order of operations)
1) y=-1*9+6
y=-3
2) y=0*9+6
y=6
3) y=1*9+6
y=15
4) y=2*9+6
y=24
5) y= 3*9+6
y=32
Answer:
The correct answer is 34.
Step-by-step explanation:
98=3y-4
add 4 on both sides
102=3y
divide 3 on both sides
34=y
switch the number and variable
y=34!
Hope this helps!
Answer:
B) -0.4 seconds
Step-by-step explanation:
Laps: 25
Goal: -10 seconds to all 25 laps combined (10 seconds difference => -10)

Answer:
Step-by-step explanation:
You have to set each runner's plan equal to each other because they are equal in the end. You start with 7 miles for Angelo and 4 miles for Marc.
x is a variable that is multiplied by the number of weeks it takes for both runners' distances to be equal. So multiply x by the miles increased every week.
Marc = Angelo
2x + 4 = x + 7
x = 3
In 3 weeks each runner will run 10 miles for the week.
