Find x and y. Give reasons to justify your solution

Mathematics
2 answers:
Luda [366]3 years ago

Step-by-step explanation:

27 + 3y = 90

3y = 90 - 27

y = 21

27 + (21×3) + x + 8x + 18 = 180 ( angles on a straight line sum up to 180)

9x + 108 = 180

9x = 180 - 108

9x = 72

x = 72/9

x = 8 degrees

Answer:

Y=21

X=8

Step-by-step explanation:

In the middle there is a right angle

therefore 27 +3y=90

Y will be 21

Then x+27+63+8x+18=180

x=8

Hence 8+27+3(21)+8(8)+18=180

Judy uses 9.7 pints of blue paint and white paint to paint her bedroom walls.3/5
Sindrei [870]

Answer:

3.88 Pints

Step-by-step explanation:

First we need to find the amount of blue paint that was used. We can do that by multiplying 9.7 by 0.60 since that is 3/5 in decimal form

9.7*0.60=5.82

Now we know how much blue paint was used, now we just need to find how much white paint was used. We can do that by subtracting our amount of blue paint from the total amount of paint used

9.7-5.82=3.88

thus, 3.88 is the amount of white paint used
