17,400 - 3000 = 14,400

Let x be the number of months.

300x = 14,400

Divide by 300.

x = 48

12 months = 1 year

4 years is the answer.

Answer:

4 years

Step-by-step explanation:

Equation: 300x + 3000 = 17400

Subtract 3000 from both sides;

300x = 14400

Divide both sides by 300;

x = 48 months

48 months = 4 years

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

4х – Зу = 15
x - 2y = 0 solve using substitution please show work

Answers

Answer:

(6,3)

Step-by-step explanation:

I'm going to start with the second one.

x - 2y = 0

   +2y  +2y

x = 0 + 2y   which is the same as (x = 2y)

Now plug that in for the x-value in the other equation.

4(2y) - 3y = 15

8y - 3y = 15

5y = 15

Divide both sides by 5

y = 3

Here is where you are going to plug it back into the first one we did.

x - 2(3) = 0

x - 6 = 0

  +6   +6

x = 6

So the answer is (6,3)

Hope that helps and have a great day!

Josiah cell phone plan allows a number of minutes of air time for $20 a month each minute costs 0.02 $ how many minutes of air time is he allowed?

Answers

Given parameters:

Cost of cell phone plan per minute  = 0.02$/min

Amount in a month  = $20

Unknown:

Number of minutes allowed per month?

Solution:

 The number of minutes = [tex]\frac{amount per month}{rate per call}[/tex]

     Input the parameters and solve;

                                         = [tex]\frac{20}{0.02}[/tex]

                                         = 1000min

The number of minutes allowed per month is 1000min

the area of a trapezium is given by the formula A=1/2h(a+b), where h is the height and a and b are the measures of the two bases. what is the height of a trapezoid with an area of 24 square inches if the two bases measure 4 inches and 6 inches?

Answers

Answer:

[tex] h = 4.8 \: inches.[/tex]

Step-by-step explanation:

[tex]A= \frac{1}{2} h(a+b) \\ h(a + b) = 2A \\ h = \frac{2A}{(a+b)} = \frac{2 \times24 }{4 + 6} \\ h = \frac{48}{10} \\ h = 4.8 \: inches.[/tex]

Answer:

h=4.8

Given:

area=24 , a=4 , b=6

To find:

height

Step-by-step explanation:

A = [tex]\frac{1}{2}[/tex] × h(a+b)

24 = [tex]\frac{1}{2}[/tex] × h(4+6)

24 × 2 = h(10)

48 = 10h

48/10 = h

h=24/5

h=4.8

therefore, height of the trapezium is 4.8

hope it helps you!
