Answer:
x=6/5 or 1.2
Step-by-step explanation:
2.5x=x+3
2.5x-x= 3
2.5x= 3

x= 6/5 or 1.2
Answer:
A. 13m
Step-by-step explanation:
To find the area of a square you multiply Length by the Height. Since squares have equal length sides the number has to be the same for the length and the height.
13 x 13 = 169

Answer:
n = -8
Step-by-step explanation:
Given the expression
(-2y-3) + (-6y-5) = (ny -8),
Expanding the LHS
-2y-3 - 6y -5 = ny - 8
-2y-6y-3-5 = ny - 8
-8y - 8 = ny - 8
Compare both sides
-8y = ny
-8 = n
Swap
n = -8
Hence the value of n is -8
