Answer: Subtraction Property of Equality
<em>Step-by-step explanation:</em> The Subtraction Property of Equality tells us that
we can subtract the same quantity, or equal quantities,
from both sides of an equation.
To get from the statement 7x + 11 = 39 to 7x = 28,
we subtract 11 from both sides to get 7x = 28.
4/3
1.3 repeating
1 1/3
These are all correct. To divide fractions take the reciprocal (invert the fraction) of the divisor and multiply the dividend. This is the quickest technique for dividing fractions. The top and bottom are being multiplied by the same number and, since that number is the reciprocal of the bottom part, the bottom becomes one. Or just use a calculator lol.
1) 3^6 * 3^5 = 3^11
2) 2^3 * 2^7 = 2^10
3)7^2*7^6 = 7^8
hope it helps
I hope this helps so the first one should be right
Answer:
m = 5
Step-by-step explanation:
We are told that the two triangles are similar. Thus, each side of the larger triangle is the same multiple of the corresponding side in the smaller triangle.
Thus, 12 = k(7.2), where k is the constant of proportionality.
Solving this for k, we get
k = 12/7.2 = 1 2/3
Thus, side m is 1 2/3 times 3, or 5/3 times 3, or just 5.
m = 5
