Answer: X would equal -7
Step-by-step explanation: First off, we cross multiply. So 374/(x-10) = -22/1 would be: 374 = -22(x-10). We then get 374 = -22x +220. You would subtract 220 from both sides then divide by -22 to get x. You could then substitute -7 in for x, to check your answer.

Brooke bought 5 plates for $44. If the price of the plates is always the same, which represents the total cost, y, of buying any number of plates, x?
5 y = 44
y = 8.8 x
On a coordinate plane, the x-axis is labeled number of plates and the y-axis is labeled total cost (in dollars). A line goes through points (2, 30) and (4, 40).

1.Jamal sells sandwiches. He spends $2.70 per sandwich on ingredients and then adds a 110% markup. What is the selling price of one sandwich?
2.Elizabeth goes to a restaurant where her bill comes to $18.50. She leaves the server a 22% tip. What is the total cost of going to the restaurant?
Answers
Answer:
2.70 + 110% = 5.67$ per sandwich
110% out of 2.70 is 2.97, so 2.70+2.97 = 5.67
18.50 + 22% = 22.57$ total cost
22% out of 18.50 is 4.07, so 18.50+4.07 = 22.57
Joe borrowed $9,000 from the bank at a rate of 7% simple interest per year. How much interest did he pay in 5 years?
Answers
Explanation:
From the Formula:
I = Pin
where : I - interest
P - principal
i - the interest rate
n - the number of years
I = Pin, plug in the given data as provided in the problem.
P = $2,000
i = 0.07 per year
n = 5 years
I = ($2,000)(0.07/year)(5 years)
= ($2,000)(0.07)(5)
= $700

which of the following equations represents the data in the table
Answers
Answer:
B
Step-by-step explanation:
if you graph all the points you have a negative slope. the y intercept is (0,2) and the rise over run is 3/4 with the negative slope the answer is: y= -3/4+2
Answer:
Your answer should be B.
Step-by-step explanation:
I got answer B because the equation is in the form y = mx + b whereas, m is the slope and b is the y-intercept. To figure out the slope I used the equation x1 - x2 / y1 - y2. The slope was (-3/4). To figure out the y-intercept I just looked at the table and where there was a 0 in place of x and the y there was 2. My y-intercept was 2. So, I got the equation, y = (-3/4)x + 2, which is option B.

What is the total cost of a cell phone that costs $97.03 if there is an eight percent sales tax?
Answers
Answer: $104.79 (rounded to nearest penny)
Step-by-step explanation: Okay, so you know how you can multiply a number by a percent to get part of that number? Since you have the sales tax, 8%, you could multiply the original price by 8%, or 0.8, to get 7.76 (rounded to the nearest penny)- that's how much you would have to pay extra, since sales tax is an additional cost to your original price. From there you could just add 7.76 to 97.03 to get $104.79.
A shorter way:
Multiply by 108%, or 1.08, since you have to pay 100% of the cost plus an additional 8%. That will give you that exact amount without the extra step :)
Use the graph below to fill in the blank with the correct number:

Answers
From the graph,

Notice that when x = 0, y = 1.
If we plot the point (0,1) It's the same point. So f(0) = 1 is basically substituting x = 0 and get y = 1

twelve eggs cost $3.12. how much does one egg cost
Answers
Answer:
.26 cents
Step-by-step explanation:
3.12 divided by 12.
each individual egg is priced at $0.26
To find the cost of one egg, we can divide the total cost by the number of eggs. In this case, since twelve eggs cost $3.12, we can calculate the cost of one egg by dividing $3.12 by 12.
Dividing $3.12 by 12 gives us $0.26. Therefore, one egg costs $0.26.
This means that each individual egg is priced at $0.26. If you were to purchase just one egg from the given batch, it would cost $0.26.
Calculating the cost per unit helps us determine the price of individual items when they are sold in a larger quantity or package. In this case, dividing the total cost by the number of eggs allows us to find the cost of a single egg.

Given the triangle below, what equation would you use to solve for x? Use your equation to determine the TWO unknown angle measurements.
Answers
Answer:
x=15
Step-by-step explanation:
so we are given one angle 90, although x is used in both so you can add them. We know that the sum of angle measures in a triangle is 180 so the equation is: 90+6x=180
subtract 90 from both sides: 6x=90
divide by 6: x=90/6
simplify: x=15
