The solutions to the given expressions are given below:-

1. 5x +3x            ⇒   8x

2. 7x²- 5x²         ⇒   2x^2

3. 2xy +4xy       ⇒   6xy

4. 8y - 3y           ⇒   5y

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The expressions will be solved as:-

1. 5x +3x

The sum of 5x and 3x is equal to 8x.

5x +3x = 8x

2.. 7x²- 5x²

The substraction of 7x² and 5x² is equal to 2x².  

7x²- 5x²  = 2x²

3. 2xy +4xy

The sum of 2xy and 4xy is equal to 6xy.

2xy +4xy = 6xy

4. 8y - 3y

The subtraction of 8y and 3y is equal to 5y.

8y - 3y = 5y

Answer: The speed of the car is 45.3 miles per hour.

Step-by-Step Explanation: Let 'x' be the speed of the car.

60 × 2/3 = 120/3 = 40

30 × 1/5 = 151/5

151/5 /40 = x / 60

151 / 200 = x / 60

=> x = (151×60) / 200

=> x = 45.3

Answer:

The car was traveling at an average speed of 45.3 miles per hour.

Step-by-step explanation:

We need to figure out how many minutes are in 2/3 of a hour. If we divide 60 minutes by 3 we get 20 minutes, so 2/3 of 60 minutes is (20 minutes x 2) 40 minutes.

We now know that the car traveled 30.2 miles in 40 minutes. We want to know if it traveled for 60 minutes, what would the average speed be. The ratio will be the same, so we want to solve for x (miles):

30.2/40=x/60

We then cross multiply:

30.2x60=40(x)

1,812=40(x)

Divide each side by 40

1,812/40 = x

x=45.3

Answer:

D.

Step-by-step explanation:

Form an equation. 593 = 418 + 12.50d

The variable d represents how many days she needs to pet-sit for.

Use the subtraction property of equality by removing 418 from both sides.

593 - 418 = 418 - 418 + 12.50d

175 = 12.50d

You will need to divide both sides by 12.50 to get the variable by itself.

14 = d

You've gotten the answer now, 14.

Answer:

its true because 3(4a - 2) is 12a - 6

Answer:

True

Step-by-step explanation:

its true because 3(4a - 2) you would do 3 x 4a and instead of 4 - 2 you would change it to 4 + 2 after that you would do 3 x 4a = 4a + 2 which gives you

12a - 6

so yes they are equivalent

Answer:

alrighty then, x has to be 14, so x-3=11 which means the question mark would be 3. you can do the rest yourself, I believe in you!

Step-by-step explanation:

To solve this problem, we are required to write and expression to solve for the missing side in each figure.

To find the missing side of the square, we can simply write it as

[tex]15 = h + x\\x = (15 - h)m[/tex]

For the triangle, to find the missing side let's calculate the area of the triangle

[tex]area = \frac{1}{2} base * height\\area = \frac{1}{2} * 5 * 12\\area = 30m^2[/tex]

But for the length of the missing side, we can simply write it as

[tex]b = 10 + x\\x = (b - 10)m[/tex]

The expressions for the missing sides are;
