What mistake did Crystal make? What is the correct answer to 5(4 + 7)?
Type a paragraph
The value of 5(4 + 7) is 55.
It is required to find the correct answer.
Simplification means simplifying processes involved in work towards consistency of efforts, costs and time. It eliminates useless and disadvantageous (or unnecessary) diversity and variety.
Given that:
By the Distributive Property
If a, b, c are real numbers, then
a*(b+c)=a*b+a*c
Crystal's did mistake was that she distributed the 5 only to the 4, not to the 5 to 7 as well.
First distribute and then multiply, we get
The correct step should have been
= 5(4 + 7)
= 5⋅4 + 5⋅7.
= 20 + 35.
= 55
Therefore, the value of 5(4 + 7) is 55.

Answer:
Crystal's mistake was that she distributed the 5 only to the 4, not to the 7 as well.
The correct step should have been 5(4 + 7) = 5⋅4 + 5⋅7.
Using the distributive property correctly would give the sum of the two products, 20 + 35. The value of 5(4 + 7) is 55.

Answer:
8 38/45 inches
Step-by-step explanation:
A regular size chocolate bar is 5 and 4/9 inches long. If the king size bar is 3 and 2/5 inches longer, what is the length of the king size bar?
Let us represent:
Length of regular size chocolate bar = x
Length of king size chocolate bar = y
A regular size chocolate bar is 5 and 4/9 inches long.
x = 5 4/9 inches
If the king size bar is 3 and 2/5 inches longer,
Hence:
y = x + 3 2/5 inches
The length of the king size bar is calculated as:
5 4/9 inches + 3 2/5 inches
(5 + 3) + ( 4/9 + 2/5)
Lowest common denominator = 45
8 + (20 + 18/45)
8 38/45 inches
The king size chocolate bar is 8 and 26/45 inches long, which is calculated by adding the given lengths of the regular bar and the additional length of the king size bar.
The question asks about the length of a king size chocolate bar given the lengths of a regular size bar and the additional length of the king size bar. To find the length of the king size bar, we need to add the additional length to the length of the regular bar. The regular bar is 5 and 4/9 inches long and the king size bar is 3 and 2/5 inches longer. If we add these lengths together:
5 4/9 + 3 2/5 = 8 and 26/45 inches
So, the length of the king size bar is 8 and 26/45 inches.
This problem involves basic arithmetic with fractions, which is a common concept in Mathematics for Middle School students. Remember that when adding fractions, you need to have the same denominator.
