Answer:
A. 6y
Step-by-step explanation:
The profit formula is: total earnings- total expenses. In this case the 145 has a minus sign, which indicates that these are Debra's total expenses. Then, 6y represents total revenue. You can also identify that this is the answer because revenues depend on babysitting hours, which in this case, is represented by the variable "y".
132 + 146 + c is greater than or equal to 325, and c is greater than or equal to 47.
Answer:
4
Step-by-step explanation:
We need to perform a multiplication.
The following rule is applied:
A/B C = AC/B
In our example, the factors in the new numerator are:
28, 1,
Notice that all non-fraction factors are placed in the numerator.
The only factor in the new denominator is:
7
We need to reduce this fraction to the lowest terms.
This can be done by dividing out those factors that appear both in the numerator and in the denominator.
In our example, this is the common factor:
7
We need to evaluate a power by multiplying the base by itself as many times as the exponent indicates.
In our example, base 2 will be multiplied by itself twice.
Then we're left with our answer: 4
Answer:
Each check was $30.99
Step-by-step explanation:
Subtract:
$451.89 - $358.92 = $92.97
Divide:
$92.97 ÷ 3 = $30.99
This means each of the three checks were $30.99
Answer:
3, 3, -60
Step-by-step explanation:
The area of a rectangle is equal to the product of its length and width. So, to create an equation representing the area of this rectangle, multiply the length, , and the width, , and set the product equal to the area, 54.
Then rewrite the equation using the distributive property, and move all terms to the left side of the equation.
So, the equation to find the value of n is .
