Answer:
90°
Step-by-step explanation:
5x+20=9x
20=4x
5=x
<DEG=5x+20+9x=5(5)+20+9(5)=25+20+45=90
So first you would figure out what 1/3 of 30 is($10), then figure out what 1/4 of the money is($7.50) then add the two together, then subtract that number from 30, and then figure out what fraction that number is
3x+2y=8
y=x-6
3x+2 (x-6) =8
3x+2x -12 =8
+12 to both sides...
3x+2x = 20
3x+2x=5x
5x=20
divide both sides by 5
x=4!!!
y=-2
