Answer:

480

Step-by-step explanation:

So we have the expression:

-8(2z-70)

And we want to evaluate it for z=5 and c=2:

So:

=-8(2(5)-70)

Multiply within the parentheses:

=-8(10-70)

Subtract within the parentheses:

=-8(-60)

Multiply:

=480

Math <br><br><br> help pls!!<br><br> solve for x and y
Elan Coil [88]

Answer:

x = 7 ,  y= - 6

Step-by-step explanation:

4x = -2 - 5y ___(1)

4x= 10 - 3y ___(2)

so, now by simultaneous equations,

10 - 3y = - 2 - 5y

2y = -12

y = -6

if y = -6

then, 4x= 10 -3(-6)

4x =28

x = 7
