Answer:
x = 50
Step-by-step explanation:
You are correct.
x + m<PQS + m<PSQ = 180
m<PQS = m<QRT = 70
m<QST + m<PSQ = 180
120 + m<PSQ = 180
m<PSQ = 60
x + 70 + 60 = 180
x + 130 = 180
x = 50
Great job!
We have the following expression:
(27x 4 - 18x 3 + 9x 2) ÷ 3x
Dividing each term between 3x we have:
9x3 - 6x2 + 3x
We can check the result:
(9x3 - 6x2 + 3x) * (3x)
= (27x4 - 18x3 + 9x2)
Division OK.
Answer:
The result of the division is:
9x3 - 6x2 + 3x
Question: If 80 is increased by 50%, what is the new amount?
Answer: 40
Answer:
x= 15 and y=4
Step-by-step explanation:
Let's start by finding y first using the basic proportionality
= 
- 12*6 = 18y
- 72 = 18y
- y = 72/18
- y= 4
now time to find x using the same way:
=
