Answer:
division property of equality
Step-by-step explanation:
First in order to solve we must learn the properties of equality:
Addition property of Inequality:
If a > b , then a + c > b + c
substraction property of inequality
If a > b , then a - c > b - c
Multiplication property of inequality
If a > b , then a * c > b * c (if c > 0)
Division property of inequality
If a > b , then a / c > b / c (if c > 0)
Step 3: 2x>10
Step 4: x>5
When we divide by 2x/2 and 10/2 we get x>5 so we must use the division property of equality

find three consecutive even integers whose sum 72
Answers
22, 24, 26
Step-by-step explanation:
2n - 2 + 2n + 2n + 2 = 72
6n = 72
n = 72/6
n = 12
∴ so three consecutive even integers whose sum is 72 :
2n - 2
= 2(12) - 2
= 24 - 2
= 22
2n
= 2(12)
= 24
2n + 2
= 2(12) + 2
= 24 + 2
= 26
verification
22 + 24 + 26
= 46 + 26
= 72 ✓✓

Answer:
x = 10
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
12x + 15 is an exterior angle of the triangle , then
12x + 15 = 4x + 10 + 85 , that is
12x + 15 = 4x + 95 ( subtract 4x from both sides )
8x + 15 = 95 ( subtract 15 from both sides )
8x = 80 ( divide both sides by 8 )
x = 10
