5x-40=3x+8
Add 40 to both sides
5x=3x+48
Subtract 3x from both sides
2x=48
Divide by two on both sides
X=24
Given:
Identify the dollar amount due on a sample of 49 credit cards.
The amount due on the next payment is any one of the averages that mode,median or mean can be used.
Answer:
m∠TRI = 43
Step-by-step explanation:
m∠TRI + m∠IRB = m∠TRB
3x - 5 + x + 27 = 86
3x + x - 5 + 27 = 86 {Combine like terms}
4x + 22 = 86 {Subtract 22 from both sides}
4x = 86 - 22
4x = 64 {Divide both sides by 4}
x = 64/4
x = 16
m∠TRI = 3x - 5
= 3*16 - 5
= 48 - 5
= 43
You first do 3 + 2, which would equal 5. Then, you would just do 3/5.
