To find the sum of fractions, the denominators have to be the same. So:
7/10 +  8/10 = 15/10 because
4/5 * 2 = 8/10 which will leave us with the same denominator as 7/10.

Can someone help geometry is confusing
NikAS [45]

<LMP and <NMP are supplementary angles so sum = 180

<LMP +  <NMP = 180

(-16x + 13) + ( - 20x + 23) = 180

-16x + 13  - 20x + 23 = 180

-36x + 36 = 180

-36x = 144

    x = -4

<LMP = -16x + 13 = -16(-4) + 13 = 77

<NMP = - 20x + 23 = - 20(-4)  + 23 = 103

Answer

<LMP  = 77°

<NMP  = 103°

Answer:

I’m guessing you subtract the numbers from the inside of the parenthesis and then multiply the two.

(-5)(-11) = 55

I hope this is correct.

docker41 [41]

Answer: -1t + 720

The amount earned is therefore;

= 7t + (8 * (90 - t))

= 7t + 720 - 8t

= -1t + 720
