For this case, the first thing we must do is define variables:
x: first number
y: second number
We now write the system of equations:
x + y = 20
y = 2x + 35
Solving the system we have:
x = -5
y = 25
Answer:
The numbers are:
x = -5
y = 25
64 is a perfect square that provides 8 rows , and each contains 8 seats, this is the first perfect square after 50
There are no values of X that make the equation true therefore there is no solution
Answer:
(16)(1) => identity property of multiplication
2(3+7) = 2(3) + 2(7) => distributive property
(2+6) + 3 = 2+ (6+3) => associative property
9+0 = 9 => identity property of addition
8 x 4 = 4 x 8 => commutative property
-1.25 or -1 1/4 that’s because the dot is in between a half and a whole number so one half divided by two is 1/4
