Answer:
400 meters
Step-by-step explanation:
We are told in the question that:
Jake runs the 100-meter dash in
track.
Erika runs a race 400% the distance of Jake's race.
Hence, the length of
Erika's race is calculated as:
400% × 100 - meter
= 4 × 100- meter
= 400 meters
Therefore, Erika's race was 400 meters long.

Answer: D) 32
-6.867
You do 13 divided by 15 the plug in the -6 in the front
Answer:
For no. 1:
One of the equations say that y=-7x
So plug in -7x to the other equation as y so you equation would be
-7x= -6x-7
And then, just solve for the variable:
*add -6x to both sides*:
-x= -7
*multiply both by negative one to get a positive variable*
FOR NUMBER 1, THE ANSWER IS:
x=7
Y=-7
For no. 2:
-y=x and your other equation is 3x+5y=20
Plug in x as -y:
-3y+5y=20
*simplify*
2y=20
*divide by 2 on each side to get 1 variable alone*
Y=10
FOR NUMBER 2, THE ANSWER IS:
x=-y
Y=10
