Triangle = Equilateral Triangle
Therefore, all sides are equivalent to each other.
WORKING OUT:
5x - 22 = 4x - 10
5x - 4x = - 10 + 22
x = 12
CHECKING USING OTHER EQUATION COMBINATIONS:
4x - 10 = 3x + 2
4x - 3x = 2 + 10
x = 12
5x - 22 = 3x + 2
5x - 3x = 2 + 22
2x = 24
x = 24 / 2
x = 12
ANSWER:
x = 12
Answer:
Step-by-step explanation:
Givens
Let a = the first number
Let b = the second number
Equations
a + b = 39
b = 1/2 * a + 6
Put the second equation into the first one
a + 1/2 * a + 6 = 39 Simplify the left.
(3/2)a + 6 = 39 Subtract 6 from both sides
(3/2)a + 6 - 6 = 39 - 6 Combine
(3/2)a = 33 Multiply both sides by 2
3a = 33*2
3a = 66 Divide both sides by 3
3a/3 = 66/3
a = 22
b = 1/2 a + 6
a = 22
b = 1/2 * 22 + 6
b = 11 + 6
b = 17
Check
22 + 17 = 39
