Plz help me and explain how you got the answer plz

1 answer:

3 0

The decrease was 3. (from 30 down to 27)

Always calculate the decrease as a percent of the ORIGINAL number.

3/30 = 0.1

To change a decimal to a percent, move the point 2 places that way ==> .

0.1 = 10% .

When you go from 30 to 27, that's a decrease of 10% .

RS bisects TU at Q. If TQ=5k-9 and QU=15-x

snow_lady [41]

Answer:

x = 4, TU = 22

Step-by-step explanation:

Given that TS bisects TU at Q , then

TQ = QU , substitute values

5x - 9 = 15 - x ( add x to both sides )

6x - 9 = 15 ( add 9 to both sides )

6x = 24 ( divide both sides by 6 )

x = 4

Thus

TU = 5x - 9 + 15 - x = 4x + 6 = 4(4) + 6 = 16 + 6 = 22
