Answer:
16x^2
Step-by-step explanation:
(4x)^2
This can be rewritten as
(4x)*(4x)
4*4 *x*x
x*x is the same as x^2
16 x^2

T M - time that Maria drove;
49 * t C + 52 * t M = 191
t C + T M = 3.8 hours
t C = 3.8 - t M
49 * ( 3.8 - t M ) + 52 * t M = 191
186.2 - 49 t M + 52 t M = 191
3 t M = 191 - 186.2
3 t M = 4.8
t M = 4.8 : 3
t M = 1.6 hours
Answer:
Maria drove 1.6 hours.
Answer:
x=4, y=-2
Step-by-step explanation:
-5x+8y=-36
5x+7y=6
eqn 1+ eqn 2 gives
15y=-30
divide both sides by 15
y=-2, put in eqn 2
5x+7(-2)=6
5x=20 divide both sides by 5
x=4
