Answer:
y = -1/4
Step-by-step explanation:
y/5 +3/10 = (y+2)/7
The LCD is 10·7 = 70. Multiplying the equation by 70 gives ...
14y +21 = 10(y +2)
14y +21 = 10y +20 . . . . eliminate parentheses
4y + 21 = 20 . . . . subtract 10y
4y = -1 . . . . . . . . . subtract 21
y = -1/4 . . . . . . . . .divide by 4
_____
<em>Check</em>
(-1/4)/5 +3/10 = (-1/4 +2)/7 . . . . . substitute for y
-1/20 +6/20 = (7/4)/7 . . . simplify a bit, rewrite 3/10
5/20 = 1/4 . . . . . . . . . . true

Answer:
honestly man im stuck on the same one on edg
Step-by-step explanation:
Supplementary angles , when added, = 180
complimentary angles, when added, = 90
< AQC + < GQC = 180.....supplementary
< BQD + < DQE = 90.......complimentary
< CQE + < EQF = 90.......complimentary
< GQF , < FQE.....neither
< BQC + < DQC = 90....complimentary
< W and < X are supplementary...
if < W = 37, then < X = (180 - 37) = 143
< S and < T are complimentary
if < S = 64, then < T = (90 - 64) = 26
< C and < D are supplementary
if < C = 83, the < D = (180 - 83) = 97
cant read all of the last one.....but if they are complimentary, and
< U = 41, then the other angle is : (90 - 41) = 49
