Simplify 3^3
= (9-27) + (27-3)
= (-18) + (24)
= 6
Answer:
x = -2
Step-by-step explanation:
you need to use the distribution property first!
4(x + 5) = 12 ------> 4x + 20 = 12
now you need to subtract 20 from both sides so that you can isolate x
4x = -8
finally, divide -8 by four so that x is alone, meaning solve to find x!
x = -2
Answer:
Solving for x;
2x + 85 + 5x + 29 = 930
combine like terms:
7x + 114 = 930
-114 -114
7x = 816
/7 /7
x = 116.57, now we replace the x with it's actual value:
∠ZT = 2(116.57) + 85 = 318.14°
∠ZV = 5(116.57) + 29 = 611.85°, lets double check if they both equal 930;
318.14 + 611.85 = 929.99, which is close to 930 so we are correct.
