So he has to paint 255 m from the 280 m of paint he has
First divide 255/280 to give you a decimal
You should get .9107
Since this is in decimal form (out of 1) you want to get percentage which is out of 100 you multiply by 100
So .9107 times 100
This gives you the percentage which is
91.07%
Now it says round to 1 decimal so it would be
91.1%
Answer:
$7.59
Step-by-step explanation:
If 3 pairs of gloves costs $22.77, then 1 pair of gloves costs $22.77 ÷ 3.
$22.77 ÷ 3 = $7.59
1 pair of gloves costs $7.59.
Answer:
5
Step-by-step explanation:
Since you're familiar with the decimal equivalents of eighths, you know that ...
0.625 < 0.7 < 0.750
5/8 < 7/10 < 6/8
Ana can pour 5 glasses of chocolate milk from the amount she has.

You can also write an inequality ...
(1/8)g ≤ 7/10
g ≤ (7/10)(8) = 5 6/10 . . . . . multiply by 8
Ana can pour 5 glasses, but not quite 6.
You're first problem is unclear as I am not sure if that t was suppose to be there or not.
but as for the second one (33.7y+8.4-2.04y) we would first have to combine like terms so you'd subtract 2.04y from 33.7y , which would give you ; 33.66y so now your answer would be " 33.66y + 8.4 ",
there's nothing more you can do because they're seperate terms c: .
Your third problem ( 4.2x+8.1x+1.8x-2.1x ) is also combining like terms. Add the first 3 terms and that'll give you 14.1x , now subtract 2.1x and that'll give you "12x" as your final answer ~
For your fourth problem x+2 ( x-y ) , you would have to do something called factoring , basically all you gotta do is distribute term by term. So, x times x would give you x^2 , x times -y would give you -xy , 2 times x is 2x , and 2 times -y is -2y , so that'll look somethng like x^2 - xy + 2x - 2x . Now the 2x's cancel out
and you are left with "x^2 - xy" as your final answer ~
