The sum of 2 times a number and 8 is 7

Answers

Answer:

The number is -1/2

Step-by-step explanation:

Let x be the number

2x+8 = 7

Subtract 8 from each side

2x+8-8 = 7-8

2x = -1

Divide each side by 2

2x/2 =-1/2

x = -1/2

The number is -1/2

Answer:

2x + 8 = 7

x = -1/2

Step-by-step explanation:

"a number" can be signified by a variable.

So 2 times a number would give you 2x

And 8 would mean to add 8.

Is 7 means the end result is 7.

So 2x + 8 = 7

x = -1/2

. The equation y=5+0.5x represents the cost of getting a car wash and using the vacuum for x minutes. What is the y-intercept?

The y-intercept is 5.
The y-intercept is -5.
The y-intercept is 6.
The y-intercept is -6

Answers

The correct option is A. The y intercept is 5 and the slope is 0.5. When you write the equation in slope intercept form, by finding the x and y values, it is y=0.5x+5, therefore the y intercept is 5. You can find out by graphing the equation also but it wouldn’t be necessary.

First we need to identify the cost of each hotdog for each brand. I'll go by in order.

Ball Park:

We know that it cost $6.95 and it's 8 dogs for each one. Meaning all we have to do is divide the price by the amount of hot dogs.

"Price/Hotdogs per package"

In order

6.95/8=0.86875 or 0.87

8.20/10=0.82

7.35/8=0.91875 or 0.92

17.50/24=0.7291666 or 0.73

Since we're dealing with currency we would most likely round it by the nearest hundredth so the true answer would be $0.87.

Use this formula that I made for this question for any other questions.

Answer:

answer for y=2/3x+2: y=2/3x+2

answer for -2x+3y=6: x=3/2y-3

pls give brainliest

Answer:

There are infinitely many solutions.

Step-by-step explanation:

There are infinitely many solutions because if you solve the equations, you will find that both of the equations are actually the same, so there is infinitely many solutions.

Showing that both equations are equal: y=2/3x+2 -2x+3y=6

y=2/3x+2 Multiply by 3 on both sides

3y=2x+6 Rearrange (-2x on both sides)

3y-2x=6 More rearrangement

-2x+3y=6 Now, if you look back at the second equation, you will see that they are both the same.
