You have 24 coins valued at $3.00. Some of the coins are dimes and some are quarters. Find the number of each coin that you have.

Answers

Answer 1

Answer:

10 Quarters and 5 dimes

Step-by-step explanation:

10 Quarters = $2.50

5 dime = $0.50

Answer 2

Answer:

20 dimes and 4 quarters

Step-by-step explanation:

So, a dime is 10 cents and a quarter is 25

So, let's say you have x dimes and y quarters

X+Y=24 (total amount of coins)

Also,

10x+25y= 300 (cents)

I just put the 3 dollars into cents

Now, you have a system of equations and we should solve it:

X+y=24 ----x=24-y

10x+25y=300

So substitute x in the 2nd equation

10(24-y)+25y=300

240-10y+25y=300

240+15y=300

15y=60

y=4

Now that you know the amount of quarters, you can just say that you will have 20 dimes since 24-4=20

So, 4 quarters and 20 dimes

Check:

20 dimes=2 dollars

4 quarters= 1 dollar

correct

Solve the equation:

7x − 2 = 26

Answers

Answer:

[tex] \large \boxed{x = 4}[/tex]

Step-by-step explanation:

Goal

Solve for x-term.

Given

Equation

[tex]7x - 2 = 26[/tex]

Step 1

Isolate x by adding 2 to both sides.

[tex]7x - 2 + 2 = 26 + 2 \\ 7x + 0 = 28 \\ 7x = 28 \\ x = \frac{28}{7} \\ x = 4[/tex]

Step 2 (Optional)

We check the answer by substituting x = 4 in the equation.

[tex]7x - 2 = 26 \\ 7(4) - 2 = 26 \\ 28 - 2 = 26 \\ 26 = 26[/tex]

The equation is true for x = 4. Hence, the solution is x = 4.

PLS HELP ME ASAP PLS ILL MARK BRAIN

Answers

Answer:

Step-by-step explanation:

1). Let the circumference C and area A of the circle are proportional,

   C ∝ A

   C = kA

   Here k = proportionality constant

   k = [tex]\frac{C}{A}[/tex]

   From the given table,

   For C = 25 cm, A = 50 cm²

   Then the value of k = [tex]\frac{25}{50}[/tex]

                                  k = [tex]\frac{1}{2}[/tex]

    For C = 50 cm, A = 201 cm²

    k = [tex]\frac{50}{201}[/tex] ≈ [tex]\frac{1}{4}[/tex]

    In both the cases proportionality constant is giving the different values.

    Therefore, Circumference and Area of the circular objects are not proportional.

2). If A = [tex]\frac{1}{2}\times r\times C[/tex]

    Then this equation will be true for all the values of r and C given in the table.

    For r = 4 cm and C = 25 cm

    A = [tex]\frac{1}{2}\times 4\times 25[/tex] = 50 cm²

    For r = 8 cm and C = 50 cm

    A = [tex]\frac{1}{2}\times 8\times 50[/tex]

    A = 200 cm²

    True for all values of 'r' and 'C'.

Which ordered pair is a solution of the equation y = 10x?

A. (−6, −60)
B. (8, 90)
C. (8, 70)
D. (−10, −80)

Answers

A is a solution.
Basically, you have to plug in your coordinate to the equation. Plug in -60 for y and -6 for x. Now it should look like:
-60 = 10(-6)
Multiply 10 by -6 to get:
-60 = -60
That is a true statement because -60 equals -60. So, A is a solution to the equation. Hope this helped!

If the ratio of the two sides of the triangles are the same then the third sides of the triangle will be parallel. Then the correct figure is D.

What is the triangle?

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

If the ratio of the two sides of the triangles are the same then the third sides of the triangle will be parallel.

⇒ 5.5/15 = 6.6/18

⇒ 0.366 = 0.366

Then the correct figure is D.
