4) A
5)B
4.5% of 70 is 3.15 and times 3 is 9.45
The expression that is equivalent to 4(x+2) is 4(x)+4(2)
Answer:
a=15x; b=8x; c=13x
180°=a+b+c=15x+8x+13x=36x
=> x=180÷36=5
=> a=15×5=75°; b=8×5=40°; c=13×5=65°
Answer:
Step-by-step explanation:
x*y*z = 107
x y ≠ 0, z = 107/(x y)
x = -1, y = -107, z = 1
x = -107, y = 1, z = -1
x = -107, y = -1, z = 1
