Solve for x:
7x + 5 + x - 3 + x = 5

Answers

Answer 1

Answer:

x=1/3

Step-by-step explanation:

9x+5-3=5

9x=3

x=1/3

Answer 2

Answer:

x=1/3

Step-by-step explanation:

7x + 5 + x - 3 + x = 5

     -5                    -5         (rewrite)

7x + x - 3 + x = 0

  7x + x + x = 9x                (collect like terms) (rewrite)

9x - 3 = 0

9x = 3

(divide both sides by 9)

x= 1/3

i think this is the answer

A sporting goods store sells shirts for $20 each. If the store offers a 40% discount, what will be the selling price of each shirt? $12, $8, $28, or $16​

Answers

Answer:

The selling price for each shirt would be 8 dollars.

Step-by-step explanation:

10% of $20 is 2 and to make a whole would be 10% x 10 = 100%

so 2 x 10 = 20

we could break this down to 2+2+2+2+2+2+2+2+2+2=20

we know that one 2 is 10% so to make 40% we need 4.

4 x 2 = 8

Answers

Answer:

[tex]-\frac{3}{2}[/tex]

Step-by-step explanation:

To find the slope of the given line, slope is the rise divided by the run of a line.

  Slope  = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

  Picking points (4, 18)  and (8, 12)

 Now;

  x₁  = 4

  y₁  = 18

  x₂ = 8

  y₂ = 12

  Slope  = [tex]\frac{12 - 18}{8-4}[/tex]   = [tex]-\frac{6}{4}[/tex]   = [tex]-\frac{3}{2}[/tex]

MATHHHH !!!! HELP!!!!

Step-by-step explanation:

I think its D whats the hint

The correct answer is option A.
Pumpkin seeds have more protein because 58.5 grams of protein divided by 6.5 ounces equals 9 grams of protein per ounce. Now, the sunflower seeds have less protein because 96 grams of protein divided by 16 ounces per pound is 6 grams of protein per ounce. To find the difference in the grams per 24 ounces, take 9 grams of protein per one ounce of pumpkin seeds and multiply it by 24 to get 216 grams per 24 ounces. 6 grams per 1 ounce of sunflower seed times 24 ounces equals 144 grams of protein per 24 ounces. So, 216 grams of protein per 24 ounces of pumpkin seeds minus 144 grams of protein per 24 of sunflower seeds, equals 72 grams, therefore there is 72 more grams of protein per 24 ounces of pumpkin seeds.

What is the solution to this system of equations?
3x + y = 17
x + 2y = 49

A. It has no solution.

B. It has infinite solutions.

C. It has a single solution: x = 15, y = 17.

D. It has a single solution: x = -3, y = 26.

Answers

The answer is D,
Multiply the first equation by 2 and you get 6x+2y=34, you can then subtract the second equation from this and you gey 5x=-15, so x is -3, you can substitute this value of x into any of the 2 equations and find the value of y

What’s the slope?? Please help

Answers

Answer:

m = 30

Step-by-step explanation:

To find the slope, you can use the formula [tex]y_{2}-y_{1}\\x_{2}-x_{1}[/tex] (there should be a line between the y's and the x's to show division). Because in the numerator of the formula we have y2 - y1, we insert the second value of y and the first value of y, so it'll be 150 - 60 and we get 90. We do the same for the denominator, which will be 5 - 2 and we get 3. After this, we divide the top by the bottom, so we have 90/3 = 30.
