Simplify the expression:
10(-2c
+-8) + 6(-50 + -4)

-20c-404

Step-by-step explanation:

10(−2c − 8)+6(−50−4)

Distribute:

=(10)(−2c)+(10)(−8)+6(−50−4)

=−20c+−80+−324

Combine Like Terms:

=−20c+−80+−324

=(−20c)+(−80+−324)

=−20c+−404

=−20c−404

the answer is 31.27mph

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
