The number that each term of the equation be multiplied by to eliminate the decimals before solving -m+0.02+2.1m=-1.45-4.81m
It would be better to group all similar numbers.
<span>-m+0.02+2.1m=-1.45-4.81m
</span>-m + 2.1m + 4.81m = -1.45 - 0.02
5.91m = -1.47
The equation shown above, in order for us to eliminate the decimal,
we need to divide 5.91.
The proportion that could be used to solve for the variable is
; h = 7.5 ⇒ answer b
Step-by-step explanation:
A proportional relationship: one variable is always a constant value times the other, that constant is called the constant of proportionality
- y = k x is the equation of the proportional relationship
- We can write the proportional relationship in the form
The number of walls and the number of hours are increased or decreased together
∴ The number of walls and the number of hours are proportion
∵ 16 walls in 40 hours
∵ 3 walls in h hours
- By using the second rule above
∴
The proportion that could be used to solve for the variable is
Let us solve it to find h
∵
- By using cross multiplication
∴ 16 × h = 3 × 40
∴ 16 h = 120
- Divide both sides by 16
∴ h = 7.5
The value of h is 7.5 hours

Answer:
The statement describes that:
A person can be 9595 percent sure that the mean drive through service period of this chain is between 164.5164.5 seconds and 168.3168.3 seconds.
No, he can not do it
Step-by-step explanation:
To prove that the the given three sides can form a right triangle:
- Square the three sides
- Add the squares of the smaller two sides
- If the sum is equal to the square of the largest side, then the three given sides can form a right triangle
- If the sum is not equal to the square of the largest side, then the three given sides can not form a right triangle
∵ The designer has three partitions that are 14 , 9 and 20 feet
- Square the length of each partition
∵ 9² = 81
∵ 14² = 196
∵ 20² = 400
- Add the squares of the two smaller partitions 9 and 14
∵ 81 + 196 = 277
∵ The square of the largest partition = 400
∵ 277 ≠ 400
∴ The sum of the squares of the two smaller partitions is not
equal to the square of the third partition
- To create the apartment in the shape of a right triangle he must
have three partitions the sum of the squares of the two smaller
partitions is equal to the square of the largest partition
∴ He can not create the apartment in the shape of a right triangle
No, he can not do it
