Answer:

x=37

Step-by-step explanation:

First you set up the equation, 2x+15+3x-20=180

Then you add like terms, 5x-5=180

Add to both sides, 5x=185

Divide by 5 on both sides, x=37

The value would be 37, or X would equal 37. If you can, please mark this brainliest, so i can level up! thank you very much! :))

Step-by-step explanation:

The five fractions that provide a range of values between 1/2 and 7/8 are 5/8, 3/4, 11/16, 2/3, and 13/16.

Here are five fractions that lie between 1/2 and 7/8:

5/8: This fraction is greater than 1/2 but less than 7/8. It can be obtained by dividing 5 by 8.

3/4: This fraction is greater than 1/2 and closer to 7/8. It is obtained by dividing 3 by 4.

11/16: This fraction is closer to 1/2 and slightly less than 7/8. It can be obtained by dividing 11 by 16.

2/3: This fraction is greater than 1/2 and closer to 7/8. It is obtained by dividing 2 by 3.

13/16: This fraction is closer to 7/8 and greater than 1/2. It can be obtained by dividing 13 by 16.

These five fractions provide a range of values between 1/2 and 7/8. They demonstrate different proportions and can be used in various contexts where a fraction between 1/2 and 7/8 is required, such as measurement, comparison, or estimation.

Answers

Answer: D. $24.30

Step-by-step explanation:

I'm not completely sure.

The correct answer is C) $16.20


Here’s the math:
16.20 x 24= $388.80 (24 is the hours he worked in one day so he made $388.80 in one day)
388.80 x 12= $4665.60 (12 is the number of days he worked)
So Rick made $16.20 an hour

The value of y when solving the equation 2(y−6)+3=4y−7 is:

Answers

Answer:

-1

Step-by-step explanation:

2(y−6)+3=4y−7

2y−12+3=4y−7

2y-12+12+3=4y-7+12

2y+3=4y+5

2y+3-3=4y+5-3

2y-4y=4y-4y+2

-2y=2

-2y/-2=2/-2

y=-1

The value of y in the given algebraic expression when simplified is; y = -1

How to Solve Algebraic Problems?

We are given the algebraic expression;

2(y − 6) + 3 = 4y − 7

Expand the bracket to get;

2y − 12 + 3 = 4y − 7

Use addition property of equality to add 12 to both sides to get;

2y - 12 + 12 + 3 = 4y - 7 + 12

2y + 3 = 4y + 5

Subtract 3 from both sides to get;

2y + 3 - 3 = 4y + 5 - 3

2y = 4y + 2

4y - 2y = -2

2y = -2

y = -2/2

y = -1

A linear equation should have points that graph in a _____________ line.

Answers

A linear equation should have points that graph in a straight line.

Step-by-step explanation:

I hope it help !

A linear equation should have points that graph in a straight line.

What is a linear function?

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

A linear function is a function in which the slope remains constant.

Since a straight line has a constant slope thus it will represent the straight line.

Hence "A linear equation should have points that graph in a straight line".

What value of w makes the equation 145 = w + 27 true?

Answers

Answer:

118

Step-by-step explanation:

In the equation 145 = w + 27, you can solve for w by subtracting 27 from 145. That would give you 118. You can check this is correct by adding 27 to 118. 118 plus 27 = 145.

Answer:

118

Step-by-step explanation:

145 = w + 27

Switch the + sign before the 27 and switch into a minus and move it to the other side.

145-27=w

145-27=118

w=118
