Mathematics
1 answer:
erma4kov [3.2K]3 years ago

Answer:

108 degrees.

Step-by-step explanation:

2x + 16 = 3x - 12  (corresponding angles; AB parallel to CD).

16 + 12 = 3x - 2x

x = 28.

So the angle marked 3x - 12 = 3(28) - 12

= 72 degrees.

Angle y is adjacent to the angle so

y = 180 - 72

= 108 degrees.

Kevin and Randy Muise have a jar containing 91 coins, all of which are either quarters or nickels. The total value of the coins
BartSMP [9]
Q + n = 91
q +n -n =91-n
q= 91-n

.25q +.05n = $14.55
.25(91-n)+.05n = $14.55
22.75-.25n+ .05n= $14.55
22.75 -.20n =14.55
22.75-22.75-.20n=14.55-22.75
-.20n=-8.2
-.20n/-.20n= -8.2/-.20n
n= 41

q + 41 = 91
q +41 -41 = 91-41
q = 50

CHECK
.25(50) + 0.05(41) = $14.55
12.50 + 2.05 = $14.55
$14.55 = $14.55
