OD
the difference of twice a number and 11 cubed
Answer:
B
Step-by-step explanation:
The cube of twice a number =
[tex]{2m}^{3}[/tex]
Decreased by 11 =
[tex] - 11[/tex]
Hence, the cube of twice a number decreased by 11 =
[tex] {2m}^{3} - 11[/tex]
The cube of twice a number decreased by 11 =2n^3-11
We have given options
We have to determine the correct statement
Let us consider a number n.
What is the expression?Expressions ismathematical statements with a minimum of two terms containing numbers or variables, or both, are connected by an operator in between.
The cube of twice a number =2n^3

38.5g of sugar is needed to make 5 cakes. How much sugar is needed for 7 cakes?
Answer: 53.9g
Step-by-step explanation:
As you can't end up with a whole number by doing 7 divided by 5, first work out how much sugar is needed for 1 cake.
To find out how much sugar is needed for 1 cake, divide both sides by 5:
5 / 5 = 1
38.5 / 5 = 7.7
Therefore 7.7g of sugar is needed to make 1 cake.
Now times each value by 7 to get the answer :
7.7 x 7 = 53.9g
1 x 7 = 7
Therefore, 53.9g of sugar is needed.
Answer:
53.9g
Step-by-step explanation:
38.5 / 5 as there are 5 cakes
this will give you the amount of sugar needed for 1 cake, so you X by 7 to find out how many for 7 cakes
38.5 / 5 = 7.7
7.7 X 7 = 53.9g

Half of Sarah's wire is equal to ⅖ of Daniel's. Chris has 3 times as much as Sarah. In all, their wire measures 6 ft. How long is Sarah's wire in feet?
9514 1404 393
Answer:
1 1/7 ft
Step-by-step explanation:
Let s, d, c represent the numbers of feet of wire held by Sarah, Daniel, and Chris, respectively.
1/2s = 2/5d . . . . . . half of Sarah's is 2/5 of Daniel's
c = 3s . . . . . . . . . . .Chris has 3 times as much as Sarah
s + d + c = 6 . . . . . in all, they have 6 feet
Multiplying the first equation by 5/2, we find ...
d = 5/4s
Substituting for d and c in the last equation gives ...
s + 5/4s +3s = 6
s(21/4) = 6
s = 6(4/21) = 24/21 = 8/7
Sarah's wire is 1 1/7 feet long.
