Answer:
Step-by-step explanation:
p = power washer and g = generator
6p + 6g = 90 .....multiply by 4
4p + 8g = 100 ....multiply by -6
---------------------
24p + 24g = 360 (result of multiplying by 4)
-24p - 48g = -600 (result of multiplying by -6)
---------------------add
-24g = - 240
g = -240 / -24
g = 10 <=== the generator cost $ 10 per hr
6p + 6g = 90
6p + 6(10) = 90
6p + 60 = 90
6p = 90 - 60
6p = 30
p = 30/6
p = 5 <==== the power washer costs $ 5 per hr
check...
4p + 8g = 100
4(5) + 8(10) = 100
20 + 80 = 100
100 = 100 (correct)
9 + 4 = 13
She is 13 floors away
16 because if you put 16 into a percentage it's 80. 16 divide 20 times 100 equal 80
Let's simplify step-by-step.
−3x2−5x2(4x3−x2)(2)
Distribute:
=−3x2+−40x5+10x4
Answer:
=−40x5+10x4−3x2
Hi there, bascially decompose means two fractions that add up to 11/5. There are alot of ways to decompose 11/5 so I am only giving 3 ways to decompose 11/5.
The first way is 10/5+1/5, the second way is 9/5+2/5, and the third way is 6/5+5/5
