3. Which of the following can find 76 / 4
The correct answer is A. (2*38) / (2*2)
because you are factoring 76 and 4 and factoring out a 2 from both of them. You can later eliminate the 2s to divide 38 by 2 which is a lot easier.

4. is correct. Good job!

5. Which of the following equals 10
Your answer:
{10}^{0}
would not be correct because anything to the power of 0 is 1.
The correct answer is
{10}^{1}
Because anything to the power of 1 is itself.

6. What is
2 \frac{1}{8}  +3 \frac{1}{2}  + 2 \frac{1}{2}
To add these fractions we need to have the same denominator and we do this by finding to LCD- the lowest commen denominator which is 8 in this case.
3 \frac{1}{2}  = 3 \frac{4}{8}
2 \frac{1}{2}  = 2 \frac{4}{8}
The we can easily add up these fractions
2 \frac{1}{8}  + 3 \frac{4}{8}  + 2 \frac{4}{8}  = 8 \frac{1}{8}
The correct answer is D. 8 1/8 ft

Vlada [557]

Question is Incomplete;Complete question is given below;

Caleb made $105 mowing lawns and walking dogs, charging the rates shown. If he mowed half as many lawns as dogs walked, how many lawns did he mow and how many dogs did he walk? $7.50 for walking dogs and $20 for mowing lawns

Answer:

Caleb mowed 3 lawns and walked 10 dogs.

Step-by-step explanation:

Let the number of dogs he walked be 'd'.

Let number of lawn he mowed be 'l'.

Given:

If he mowed half as many lawns as dogs walked

So we can say that;

l=\frac{1}{2}d=0.5d \ \ \ \ equation\ 1

Now given:

Cost for mowing each lawn = $20

Cost for walking each dog = $7.50

Total amount made = $105

Now we can say that;

Total amount made is equal to Cost for mowing each lawn multiplied by number of lawn he mowed and Cost walking each dog multiplied by number of lawn he mowed.

framing in equation form we get;

20l+7.5d=105 \ \ \ \ \ equation \ 2

Substituting equation 1 in equation 2 we get;

20(0.5d)+7.5d=105

Applying distributive property we get;

10d+7.5d=105\\\\17.5d=105

Dividing both side by 17.5 we get;

\frac{17.5d}{17.5}=\frac{105}{17.5}\\\\d= 6

Substituting the value of 'd' in equation 1 we get;

l=0.5d=0.5\times6=3

Hence Caleb mowed 3 lawns and walked 10 dogs.
