Answer:
7w - 2
Step-by-step explanation:
you are subtracting w from 8w. Whenever there is a variable with no number beside it, it is an understood 1. so subtract 8w - 1w. This gives you 7w. then you move to the numbers with no variables. The 6 has a subtraction sign infront of it, which can be used as a negative sign. so -6 + 4 would be 2. therefore in whole, the answer would be 7w - 2. I do believe I am correct, but feel free to Comment if something should be corrected.
Answer:
after 2 hours, they will have the same fee.
they will have been payed 11$
Step-by-step explanation:
if you say h = hours of tutoring,
Rakim charges 7 + 2h
Joan charges 3 + 4h
since you want them to be the same, you can write the following equation:
7 + 2h = 3 + 4h
<em>subtract 2h from each side</em>
7 = 3 + 2h
<em>subtract 3 from each side</em>
4 = 2h
divide both sides by 2.
h = 2
after 2 hours, they will have the same fee.
they will have been payed 11$
"they will have been payed" ah yes the grammar.
To solve we have to write 12x as 2x+10x
<span><span>x2</span>+2x+10x+20</span>
taking x and 10 as a common
x(x+2)+10(x+2)
now (x+2) is common
<span>(x+2)(x+10) answer</span>
