1.75 or 7/4 as a fraction
Answer:
4 - 14 lbs
Step-by-step explanation:
Ok, so the most she can carry is 4 books. and they weigh 1 - 3.5 lbs. so you take 1 times 4. and thats well 4. then you do 3.5 times 4. thats 14 so your range would be 4 -14 lbs
I believe this is a problem dealing with proportions, so you could cross multiply and divide. so you would do 8/270 then x/72.5 , you cross multiply 72.5x8 which equals 580. then you divide that answer by 100 which equals 5.8 (:
In order to solve this problem, you double the sales price!
$17.50 x 2 = $35.00
The original price would be $35.
Hope this helps!
First distribute
a(b+c)=ab+ac
-2(x+4)=-2x-8
now we have
-2x-8-8=4
-2x-16=4
add 16 both sides
-2x=20
divide bot sides by -2
x=-10
