Simplify:
−3=12y−5(2y−7)
−3=12y+(−5)(2y)+(−5)(−7)(Distribute)
−3=12y+−10y+35
−3=(12y+−10y)+(35)(Combine Like Terms)
−3=2y+35
Flip the equation.
2y+35=−3
Subtract 35 from both sides.
2y+35−35=−3−35
2y=−38
Divide both sides by 2.
2y/2=−38/2
y=−19
3^-4 = 1/3^4 = 1/81
hope it helps!
The bill after applying the coupon = 31.84*(85%) = 27.064
so each of them will pay : 27.064/3 = $9.021
Calculator recommended.
All you'd do is $45,000 * 0.25 (25% is 0.25, 32% is 0.32, etc.)
They had a $11,250 increase. If you want the total sum then:
$45,000 + $11,250
Your Answer(s):
$11,250 increase
$56,250 in total of how much the company made.
So the question is asking to solve for y
You know RS=7y-4
You know ST=y+5
You know RT=28
RS+ST=RT as shown in the diagram, This means that you can use that equation and replace RS,ST, and RT with what you know they are equal too. So you end up with the equation:
(7y-4)+(y+5)=28, Now you have to solve for y
7y-4+y+5=28
8y+1=28
8y=27
y=3.375
