2x + 50 = 7x
50 = 5x
10 = x
2 (10) + 50
20 + 50
70
m<AEB = 70 degrees
First one (on the left) is 2) associative property because we are regrouping terms or re-associating them based on the parenthesis. Think of the parenthesis like a tent or a house that separates off the stuff outside. First 27 and 36 are grouped, then we move the parenthesis so that 52 and 27 are grouped now.
Second one (on the right) is 1) commutative. The commutative multiplication property says we can multiply two numbers in any order. For example, 4*9 = 36 and 9*4 = 36. The 4 and 9 swap places. In this problem, the 3 and 4x swap places. The use of parenthesis isn't necessary, though it is sometimes used to imply multiplication.
Answer:
C
Step-by-step explanation:
Step-by-step explanation:
sum is addition
3/2+x=11/5+4 1/2
get x alone by using opposite operation to get 3/2 on other side of equal sign
3/2 is being added to x, so the opposite is subtracting
3/2-3/2+x=11/5+4 1/2-3/2
3/2 cancels out on the left
x=11/5+4 1/2-3/2
need same denominator, all denominators are factors of 10
2×5
multiply top and bottom of each fraction to get denominator of 10
(11/5)*(2/2)
(4/1)*(10/10) and (1/2)*(5/5)
(3/2)*(5/5)
multiply top and bottom and add
x=(22/10)+(4/10)+(5/10)-(15/10)
add all numerators
x=(22+4+5-15)/10
x=16/10
now simplifydivide by 2 on top and bottom
x=(16/10)÷(2/2)
x=8÷5
5/5 is 1, and there is 3/5 left
so x=1 3/5
