mylen [45]
The correct answer is $10,982.68, because you have to subrtract $666.66 from $6,008.10 and you would get $5,341.44. The next step is that you have to add because the problem states that they're depositing, (which means putting money into the bank account), so you add the $1,100.10 and the $4,580.54 to $5,341.44 and you would get $11,022.08. Lastly the last step is to subtract the cost of the checks from your total and you would get $10,982.68.

Hope that helps.

What are the common factors for 88 and 24
Zinaida [17]
To find the common factors between two numbers, you must first break the numbers down into factors, and then find all common factors.
Let's break down 88.

88: 2 x 44, 4 x 22, 8 x 11.

Now let's break down 24.

24: 2 x 12, 3 x 8, 4 x 6.

Now that we've factored both numbers, let's select all the common factors.

Common factors:
1, 2, 4, 8.

How many solutions does the equation 5x+17=4(3x−1) have?
Stella [2.4K]

<u>Answer:</u>

one solution = 3

<u>Step-by-step explanation:</u>

Let's solve your equation step-by-step.

5x+17=4(3x−1)

Step 1: Simplify both sides of the equation.

5x+17=4(3x−1)

5x+17=(4)(3x)+(4)(−1)(Distribute)

5x+17=12x+−4

5x+17=12x−4

Step 2: Subtract 12x from both sides.

5x+17−12x=12x−4−12x

−7x+17=−4

Step 3: Subtract 17 from both sides.

−7x+17−17=−4−17

−7x=−21

Step 4: Divide both sides by -7

-7x/-7 = -21/-7 = 3
