answer:
the answer is -3 and 8
Step-by-step explanation:
we will place -3 in the equation
(x+3)(x-x)=0
(-3+3)=0 (because -3+3 will cut down together)
we will place two 8(eights) in the equation
(8-8)=0
final answer is
(0)(0)=0
so -3 and 8 fits well in the equation
Answer:
B. 0.083 rounded to the nearest thousandth.
Step-by-step explanation:
It is known that 12 inches = 1 foot and
60 minutes = 1 hour
Since we want to covert from inches per hour to feet per minute, then we would change 60 inches to feet in 1 hour 2 minutes in divide.
If 12 inches = 1 foot, then
60 inches = 60/12 = 5 feet
Therefore, the number of feet that she sews in a minute is
5/60 = 0.083 feet per minute
She sews 0.083 feet per minute.
This is the full explanation for this question.
This is saying that four is the result of a number "x" minus 12....therefore the equation is x-12=4
Answer:
He paid $51
Step-by-step explanation:
$85-40%=$51
Using a system of equations, it is found that Susan had 44 quarters, 11 dimes and 27 nickels.
--------------------------------
We are going to use:
- x as the number of quarters.
- y as the number of dimes.
- z as the number of nickels.
A <em>quarter </em>is worth $0.25. A <em>dime </em>is worth $0.1, and a <em>nickel </em>is worth $0.05. Total of $13.45, then:

4 times as many <u>quarters as dimes</u>, thus:

16 less <u>dimes than nickels</u>, thus:

Replacing in the first equation, we find x:





Now, with x, we find y and z:


Susan had 44 quarters, 11 dimes and 27 nickels.
