Answer:
Step-by-step explanation:
Consecutive interior angles are supplementary.
(x -20)° +(4x +15)° = 180°
5x = 185 . . . . . . . . . . . . . . divide by °, add 5
x = 37 . . . . . . . . . . . . divide by 5
__
74° +(5y -4)° = 180°
5y = 110 . . . . . . . . . . . divide by °, subtract 70
y = 22 . . . . . . . . . . divide by 5
P=2w+(2w-3)
60=4w-3
63=4w
15.75=w
l=2w-3
l=(2×15.75)-3
l=31.5-3
l=28.5
This answer doesn't add up so if you meant the COMBINED width then:
P=w+(2w-3)
60=3w-3
63=3w
21=w
l=2(21)-3
l=42-3
l=39
(This answer checks out so this is probably what you meant hope I helped)
If you multiply -222•10 what is the correct answer?
3 3/4 - 2 1/3
get a common denominator of 12
3 3/4 * 3/3 = 3 9/12
2 1/3 * 4/4 = 2 4/12
3 9/12 - 2 4/12=
1 5/12
Answer: they ate 1 5/12 pints
Find the GCF, then factor it out. Finally, simplify each term in the parentheses.
5x + 2x3 + 8x2
