Answer:
Step-by-step explanation:
2(9a - 6) = 2*9a - 2*6 = 18a - 12
Yes, it is equivalent.
6*(3a-2) = 6*3a - 6*2 = 18a - 12
Yes, it is equivalent.
-3(6a+4)= -3*6a + 4*(-3) = -18a - 12
No, not equivalent
3(6a+4) = 3*6a + 3*4 = 18a + 12
No, not equivalent
-3(4-6a) = -3*4 - 6a*(-3 ) = -12 + 18a = 18a - 12
Yes, it is equivalent.
Answer: D and E
the answers is between 1 and 2 so A is out
the dot is a little more than halfway so B and C are out
D and E are left :)
Answer:
? -5 -9 this the answer i think
Answer: The answer is one-twelveth.
Step-by-step explanation: Given that we have a 32 feet fence around a square garden ABCD as shown in the attached figure.
There are four equal sections AB = BC = BD = DA of the fence.
If we paint one-third of one section, then we need to find what fraction of the total fence we painted.
Since ABCD is a square, so AB = BC = CD = DA = 8 feet.
Let we paint one-third of section AB. so, the part of AB we painted is

Therefore, the fraction of the fence that we painted is given by
Thus, we painted one -twelveth of the total fence.
Solve for the first variable in one of the equations, then substitute the result into the other equation.
a=−13, b=−5
