Answer:
Mr. Vadar washed more than his son.
Step-by-step explanation:
First, you have to make these fractions have an equivalent denomoninator so you can compare them better.
2/7 is the same as 8/28 because you multiply the top and bottom by 4 due to the LCM being 28.
1/4 is the same as 7/28 which you get by multiplying the top and bottom by 7.
7/28 is bigger
Answer:
Alice is 47 pounds havier than Jamie.
Step-by-step explanation:
Let be "j" the weight in pounds of Jamie, "l" the weight in pounds of Lily and "a" the weight in pounds of Alice.
Based on the data given in the exercise, we can know that:
[Equation 1]
[Equation 2]
[Equation 3]
Solve "j" from the Equation 2:

Substitute this equatio and the Equation 3 into the Equation 1 and solve for "l":

Substitute the value of "l" into the equation
to find "j":

Substitute the value of "l" into the Equation 3 to find "a":

Subtract the weight of Jamie from the weight of Alice in order to find how much heavier is Alice than Jamie:

Alice is 47 pounds havier than Jamie.
Do you mean 5+7?
If so, that equals 12!
To solve this question, you need to do 421 divided by 9.
421 divided by 9 will get you a long number, which is 46.7777778.
Round your number up by the hundredths place. You will get 46.78.
The average speed in miles per hour would be 46.78 MPH.
Let
s--------> the length side of the cube
we know that
the volume of the cube is equal to

if the length side s is equal to 
then

and the volume is equal to


therefore
<u>the answer is the option</u>
D. A cube with side lengths of 2 feet has a volume of 8 cubic feet.
