Answer:
=53x+7
Step-by-step explanation:
Distribute:
=8x+−3+(5)(9x)+(5)(2)
=8x+−3+45x+10
Combine Like Terms:
=8x+−3+45x+10
=(8x+45x)+(−3+10)
=53x+7
Answer:
y=10000 at rate 0.12 or 12%
x=8500 at rate 0.14 0r 14 %
Step-by-step explanation:
x+y=18500 ⇒ x=18500-y
0.14x+0.12y=2390 ( solve by substitution)
0.14(18500-y)+0.12y=2390
2590-0.14y+0.12y=2390
-0.02y=2390-2590
-0.02y=-200
y=-200/0.02
y=10000 at rate 0.12
x=18500-y
x=18500-10000=8500
x=8500 at rate 0.14
check : 0.14(8500)+0.12(10000)=2390 ( correct)
