Answers

Answer:

B

Step-by-step explanation:

She wouldn't have sold just one box. Seven or more makes much sense.

Answer: The answer would be A. A girl gets $3 for every box of cookies sold plus 9 dollars for trying. She makes either $21 total or just below that amount.

Step-by-step explanation:

w is the box and when a number is beside a letter it is multiplication and then 9 dollars for trying. the < with the underline means that it is the same amount or less.

Answer:

x=31

Step-by-step explanation:

Since these angles are on a straight line, they are supplementary (combine to make 180 degrees. Therefore we can set up an equation to find x.

(5x-16)+(x+10)=180

Drop the parentheses.

5x-16+x+10=180

Combine like terms.

6x-6=180

Add 6 to both sides.

6x=186

Divide both sides by 6.

x=31

HTH :)

Answer is 31

How you solve this is:
The whole line equals to 180 degrees so add 5x-16+x+10=180 that’s will be your equation. And then subtract 10 to 180 so then it will be 5x-16+x=170 then add 16 to 170 and you will be left with 5x+x=186 add the x’s together and get 6x divide 6 to 186 and then x=31

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

7x + 3y = 12

7x - 3y = 30

Step 2: Solve for x

Eliminate y:                    14x = 42Isolate x:                         x = 3

Step 3: Solve for y

Substitute in x:                    7(3) + 3y = 12Multiply:                               21 + 3y = 12Isolate y term:                     3y = -9Isolate y:                              y = -3

Answers

B is the correct answer.
This is because the numbers in the parentheses have a negative sign in front of them. If you have an equation that "subtracts" a negative number, the sign would change to the opposite and you would have to add. To avoid that, you have to put an addition sign to subtract correctly.

Answer:

x = 33

Step-by-step explanation:

This picture shows a supplementary angle which means:

angle 1 + angle 2 = 180°

In order to solve for x, you need to add both the angles

(2x + 1) + (4x - 19) = 180° start by simplifying this equation by adding like terms

6x - 18 = 180° you can solve this like a regular inequality now, add 18 to 180°

6x = 198 now divide 6 by 162

x = 33

X=27 please mark me brainliest thanks :D

For Emily’s birthday, her father treated her and five friends to a dinner at a restaurant at the mall. Emily and her friends ordered three pizza dinners at $6.25 each and three chicken baskets at $7.50 each. All six people ordered soft drinks costing $1.25 each. The sales tax on the meal was 4.5%, and the tip was 15%. What was the total cost of the meal, including the sales tax and the tip?

Answers

6.25 times 3 is 18.75
7.50 times 3 is 22.5
1.25 times 6 is 7.5
Add those and you get 48.75.
48.75 times .045 is 2.19
48.75 times .15 is 7.31.
Add the tax and tip to the value, you get $58.25.

Answer:

$58.58

Step-by-step explanation:

the meal was $48.75

the tax was 4.5%

Multiply 48.75 by 4.5 as a decimal to do this divide 4.5 by 100 = 0.045

48.75 x 0.045 = 2.19375 round to the nearest hundreth = 2.19

48.75 + 2.19 = 50.94

tip on tax = 58.58
