Find the value of y (super easy)
1 answer:
Answer:
Step-by-step explanation:
4x + 23 + 9x - 38 = 180
13x - 15 = 180
13x = 195
x = 15
4(15) + 23= 60 + 23= 83
9(15) - 38 = 135 - 38= 97
21y - 1 + 97 = 180
21y + 96 = 180
21y = 84
y = 4
21(4) - 1 = 84 - 1 = 83

Answer:
Step-by-step explanation:
plz give brainliest
d = dimes
q = quarters
d+q = 38 coins
q=38-d
0.25q + 0.10d=6.95
0.25(38-d)+0.10d=6.95
9.5-0.25d+0.10d=6.95
-015d=-2.55
d=-2.55/-0.15 = 17
q=38-17 =21
21*0.25 =5.25
17*0.10 = 1.70
5.25+1.70 = 6.95
