Do you links of a rectangle is for X +7 and the width is three if the area of the rectangle is 129 square units what is the value of X

Answers

Answer 1

Answer:

x = 36

Step-by-step explanation:

Length of a rectangle, x+7

Width = 3

Area of the rectangle, A = 129 units²

The area of a rectangle is given by :

A = lb

So,

[tex](x+7)\times 3=129\\\\(x+7)=43\\\\x=43-7\\\\x=36[/tex]

So, the value of x is equal to 36.

9e + 4=5e + 14 + 13e

Answers

Answer:

e = -1

Step-by-step explanation:

1. 9e + 4 = 5e + 14 + 14e

2. 9e = 5e + 10 + 14e

3. 9e = 19e +10

4. -10e = 10

5. e = -1

Hope that helps

Answer:

e - 10

Step-by-step explanation:

1.) We need to manipulate the equation to get e by itself.

2.) To solve the equation, do the following steps;

9e + 4 = −5e + 14 + 13e

9e + 4 = 14 + 8e (Combine like terms)

9e + 4 − 8e = 14 + 8e − 8e (Subtract 8e from each side)

e + 4 = 14 (Combine like terms)

e + 4 - 4 = 14 - 4 (Subtract 4 from each side)

e = 10 (Combine like terms.

3.) Answer: e = 10.

Now lets check our work. To check your work, do the following steps;

9e + 4 = −5e + 14 + 13e

9e + 4 = 14 + 8e

9(10) + 4 = 14 + 8(10)

90 + 4 = 14 + 80

94 = 94

By doing those steps we can confirm the answer, e = 10, is true.

Answers

This is just the same as asking you what number when subtracted by 20.5 will give you an answer of 8. The answer would obviously be 8+20.5=28.5 so w=28.5.

We can also do it in a more algebraic way. By adding 20.5 to both side of the equation which won't change the value.

w-20.5+20.5=8+20.5

w=28.5

Calculate 48 x 3/8 choose the numbers to complete the equation

Answers

Answer:

1. Choose: 3

2. Choose: 144

3. Choose: 18

Step-by-step explanation:

The first thing you do is multiply 48 * 3/8= 18.  Then multiply 48 * 1/8= 6.  Then divide both answers to get 3, so 48 * 1/8 * 3.

Then to find the second Choose option, you know that 48 * 1/8 * 3= 18; so 18 * 8= 144(to check your answer, divide 144/8 = 18).

Finally, to find the third Choose option, you divide the fraction 144/8 = 18.
