25% means 1/4, as 25/100 is simplified into 1/4.
Multiply 18 by 4 to get your missing number.
18 x 4 = 72.
72 is your missing number.
Write an expression for the amount she added:
Dimes: 2(0.10)
Quarters: 3(0.25)
Nickels: 6(0.05)
Now write an expression for what she took out:
Quarters: 2(0.25)
Dimes: 5(0.10)
Now combine them:
2(0.10) + 3(0.25) + 6(0.05) - 2(0.25) - 5(0.10)
Simplify:
0.20 + 0.75 + 0.30 - 0.50 - 0.50
1.25 - 1.00 = 0.25 increase.
Hello from MrBillDoesMath!
Answer:
Range = { -11, -5, 4, 10}
Discussion:
g(x) = 3x- 5 =>
g(-2) = 3(-2) -5 = -6 -5 = -11
g(0) = 3(0) - 5 = 0 -5 = -5
g(3) = 4(3)-5 = 9-5 =4
g(5) = 3(5)-5 =15-5 = 10
So the range is { -11, -5, 4, 10}
Thank you,
MrB
511 is the answer you are looking for.
STEP 1:
find the portion size used to freeze; subtract all cups used from total cups of chopped tomatoes
= total cups - (cups used already)
= 25 cups - (5 1/2 + 3 3/4)
convert all to improper fractions
= 25/1 - (11/2 + 15/4)
find common denominator
= 100/4 - (22/4 + 15/4)
add in parentheses
= 100/4 - 37/4
subtract numerators
= 63/4 cups left to freeze
STEP 2:
divide cups left into 3 equal portion sizes
= 63/4 ÷ 3
to divide fractions; multiply by reciprocal of 3
= 63/4 * 1/3
multiply numerators; multiply denominators
= (63*1)/(4*3)
= 63/12
simplify by 3
= 21/4
convert back to mixed number
= 5 1/4 cups
ANSWER: There are 5 1/4 cups in each portion she froze.
Hope this helps! :)
