Answer:
6x=54
Step-by-step explanation:
3x - {7-x} =29
open bracket
3x - 7 +x =29
collect like terms and equate
4x =29 +7
4x = 36
divide both sides by 4
x = 9
.
. . 6x= 6 × 9 = 54
6x= 54
You have to use the equation (72+y)=5(4+y) which Y =+13
Answer:
A
Step-by-step explanation:
Change the mixed numbers to improper fractions
7 =
6 =
The subtraction is then
-
Both fractions have a common denominator so subtract the numerators leaving the denominator
= = → A
Answer:
x=64
Step-by-step explanation:
Both the semicircle that says 180, and the right angle sign in the image serve to support the idea that all parts of the figure equal 90
Therefore, it is safe to say that you need to subtract 26 from 90 in order to solve for x.
90-26 = 64
