Answer:
B
Step-by-step explanation:
Answer:
<u>1st pic:</u>
x = 60
y = 50
<u>2nd pic</u>:
y = 8
∠W = 28
∠Y = 128 degrees
∠X = 24
Step-by-step explanation:
<u>first pic:</u>
to find x, subtract 120 from 180 ⇒ 180 - 120 = 60
to find y, add 60 & 70 & subtract the sum from 180 ⇒ 180 - (60 + 70) = 50
<u>2nd pic:</u>
to find ∠Y, subtract 52 from 180:
180 - 52 = 128
to find y, use the following equation:
3y + 4y - 4 + 128 = 180
combine like terms:
7y + 124 = 180
subtract 124 from each side:
7y + 124 - 124 = 180 - 124
7y = 56
divide 7 on both sides:
![\frac{7y}{7} = \frac{56}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B7y%7D%7B7%7D%20%3D%20%5Cfrac%7B56%7D%7B7%7D)
y = 8
now we can find angles W and X
∠W = 4y - 4
we know that y = 8 so just substitute 8 for y
∠W = 4 x 8 - 4
∠W = 28
∠X = 3y
likewise, subtitute 8 for y
∠X = 3 x 8
∠W = 24
to check, add all angles and if they add up to 180, then its right:
24 + 28 + 128 = 180
180 = 180
Answer:
40%
Step-by-step explanation:
If there was 60 oz to begin with and now there is 36 oz now then you have to subtract 36 from 60 to find how much Jason gave to his friends. 60-36=24. 24 over 60 simplified is 7 over 15. That as a decimal would be 0.4, or 40 percent
Y - 2 = -3x + 12
3x + y = 14
