Answer:

To solve this question, we first have to know that we are trying to assemble

and solve equations with two variables: x

and y.

Assuming x

is the number of dimes and y

is the number of quarters, we

can assemble the equations.

since the number of dimes is 3 more than three times the number of quarters,

we get x=3y+3.

Additionally, multiplying the number of dimes by 0.1 and the number of

quarters by 0.25,

we get the total value of x

and y

which appears by this

equation 0.1x+0.25y=11.30

.

Substituting the value of x

in the second equation, we get 0.1(3y+3)+

0.25y=11.30

.

Solving this equation, we get that the value of x,

we get x=3×20+3=

Using the first equation to get the value of x,

we get x=3×20+3=

60+3=63

dimes.

Question is Incomplete; Complete question is given below;

Mr. Lin hires a moving company to help transport furniture to his new home. The bill from the moving company is $400. Mr. Lin includes a 15% tip with his payment.

What is Mr. Lin’s total payment, including tip?

Answer:

Mr. Lin made a Total payment of $460 including the Tip.

Step-by-step explanation:

Given:

Total bill = $400

Percentile amount paid in tip = 15%

We need to find the total payment, including tip.

Solution:

First we will find the amount paid in Tip.

amount paid in Tip can be calculated by Percentile amount paid in tip multiplied by Total bill and then divided 100.

amount paid in Tip = \frac{15}{100}\times 400 = \$60

Now we know that;

Total payment made by Mr.Lin is equal to sum of Total bill and amount paid in Tip.

framing in equation form we get;

Total payment made by Mr.Lin = \$400+\$60 =\$460

Hence Mr. Lin made a Total payment of $460 including the Tip.

At the grocery store, sliced turkey deli meat is on sale for $11 for 2 pounds. a. What is the cost per pound of sliced turkey de
alexgriva [62]

Answer:

- $5.5 per pound

- y = 5.5x

Step-by-step explanation:

Given

$11 for 2 pounds

Solving (a): Cost per pound

This is calculated by dividing $11 by 2 pounds

Cost\ per\ pound = \frac{\$11}{2\ lb}

Cost\ per\ pound = \$5.5/\ lb

Hence, the cost per pound is $5.5 per pound

Solving (b): Represent as an equation.

If 1 pound costs $5.5 (as shown in (a))

Then

x pounds costs $5.5 * x

Cost = 5.5 * x

Cost = 5.5x

This cost is represented with y

y = 5.5x
