Answer:
D is 107 and E is 38
Step-by-step explanation:
20x+40=180
20x=140
X=140/20
x=7
M<A=5(7)+3
38
m<a=m<e
15(7)+2
107
m<b=m<d
Answer:
T=98W-115W+1840
Step-by-step explanation:
$98 per credit at Westside (W)
$115 per credit at Pinewood (P)
Expression 1 : 98W+115P=T
Expression 2 : W+P=16
Combined: if W=16-P
Total=98W+115(16-W)
T=98W-115W+1840
In this case you would set it up as

(180 represents the degree of the triangle)
Add up like terms

Subtract 130 to the other side (180-130)

Divide 10 to the other side ( 50/10)
.

Hope this was clear :)
