Hi there!

To add fractions there are three simple steps:

1. Make sure the bottom numbers (denominators) are the same. → In your case you're all good, both your denominators are 8.

2. Add the top numbers (numerators) and put that answer over the denominator :

-3 + 7 = 4 → \frac{4}{8}

3. Simplify the fraction (if needed). → In your case, you do need to simplify your fraction :

Divide both your numerator and denominator by 4 to get your simplified fraction :

4 ÷ 4 = 1

8 ÷ 4 = 2

Your simplified fraction is : \frac{1}{2}


There you go! I really hope this helped, if there's anything just let me know! :)

<u><em>Answer: = 5/4</em></u>

Step-by-step explanation:

add by the numbers. add it's going to be add all together.

3+7/8

3+7=10

10/8

you can also cancel by the common factor of 2.

<u><em>=5/4</em></u>

Hope this helps!

Thanks!

Have a great day!

The height of a house is 52 ft. A tree beside the house is 7.5 ft more than twice as tall. What is the height, in feet, of the t
krok68 [10]

The height in feet of the tree is 111.5 ft.

<h3>How to find the height of a tree?</h3>

The height of a house is 52 ft.

A tree beside the house is 7.5 ft more than twice as tall.

The height of the tree is as follows:

let

x = height of the house

Therefore,

The height of the house = x = 52 ft

Hence,

height of the tree = 7.5 + 2x

height of the tree = 7.5 + 2(52)

height of the tree = 7.5 + 104

height of the tree = 111.5

height of the tree = 111.5 ft

Please show me how to solve this equation step by step!<br> 1/25(20-t)=4/25t-3/5
rjkz [21]

Remark

Multiply both sides of the equation by 25. Then you have an equation that you have already done probably.

Step One

Multiply both sides of the equation by 25

1 * (20 - t) = 4t - (3/5) * 25    Every part of the equation must be multiplied by 25

(20 - t) = 4t - 75/5                 3*25/5 = 75/5

20 - t = 4t - 15                       Add t to both sides

20 - t + t =4t + t  - 15             Combine like terms

20 = 5t - 15                            Add 15 to both sides

20 + 15 = 5t - 15 + 15             Combine like terms  

35 = 5t                                    Divide by 5

35/5 = 5t/5                             Switch sides

t = 7  Answer

which equation is in slope-intercept form and represents a line with slope 3 through the point (9,-4)
krek1111 [17]

Slope-intercept form is y = mx +b, where the variable m represents the slope of the line and the variable b represents the y-intercept of the line. Since we weren't given the y-intercept, one way to solve this problem is substitute the slope for the variable m and then the x and y values from the ordered pair to solve for b.

y = mx + b

y = 3x + b

-4 = 3(9) + b

Now, we can simplify by computing the multiplication on the right side of the equation.

-4 = 27 + b

Finally, we can find the value for b by subtracting 27 from both sides of the equation to get:

-31 = b

Now, we should substitute this value for b back into our equation with the slope.

y = 3x - 31

Therefore, your answer is y = 3x - 31.

Hope this helps!

Shad Yarbrough wants to consider the cost per use of a high-end desk top computer he is considering for his web site business. T
Sonja [21]

Answer:

Shad's cost per use will be $ 2.80.

Step-by-step explanation:

Since Shad Yarbrough wants to consider the cost per use of a high-end desk top computer he is considering for his web site business, and the computer costs $ 1,750 and has a life expectancy of four years, if Shad feels he would use the computer three days a week, on average, to determine what is Shad's cost per use, the following calculation must be performed:

Weeks per year = 52

52 x 4 = 208

208 x 3 = 624

1750/624 = X

2.80 = X

Thus, Shad's cost per use will be $ 2.80.
