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°
The answer would be 13.9 kg of gravel used per square meter
Answer:
C and A
Step-by-step explanation:
expand the things in parentheses so for C
1/2(x + 16) = 1/2(x) + 1/2(16) = 1/2 x + 8
same process for A
Answer:
x=26
Step-by-step explanation:
since the equation is vertical to 155 the equation would be
5x + 25 = 155 and then you would solve for x like this
