Answer: x = 13 and x = 4
Step-by-step explanation:
12)
(11x-15) + (5x - 13) = 180
we can collect like terms:
16x - 28 = 180
Then balance the equation to 16x = answer
add 28 to both sides
16x = 208
Then divide both sides by 16:
x = 13
14)
PQR = 82^o
And QS bisects (cuts in half) PQR, meaning that either side of QS is the same.
This means that PQS = 41^o and (10x + 1) = 41.
To balance this equation, we take away 1 from either side and then divide both sides by 10:
10x = 40
x = 4
This shows that x = 4.
