Answer:
C
Step-by-step explanation:
If you add the first equation up you get 2z+6 by combining like terms
if you see A a is equal to 3z+6 so a doesn’t work
If you look at B b is equal to z+12 so b doesn’t work
finally C if you distibute it out you get 2(z)+2(3) which equal 2z+6 which works
C
Answer:
-83, -85
Step-by-step explanation:
Multiple: 15 * 3 = 45
Multiple: 15 * 12 = 180
Add: 45 + 180 = 225
Unary plus: +15 = 15
Multiple: 225 * 15 = 3375
= (3375)
Multiple: 5 * 7 = 35
Add: +(35) = 35
= (35)
