Solve for x:

1.

4x - 7 = 3

Add 7 to both sides

4x = 10

Divide both sides by 4

x = 10/4

Simplify:

x = 5/2

Answer for question 1: x = 5/2

2.

13 + 2x/3 = 15

Multiply both sides by 3

39 + 2x = 45

Subtract 39 from both sides

2x = 6

Divide both sides by 2

x = 3

Answer for question 2: x = 3

3.

10x + 7 = 15

Subtract 7 from both sides

10x = 8

Divide both sides by 10

x = 8/10

Simplify

x = 4/5

Answer for question 3: x = 4/5

Step-by-step explanation:

We have to find the value of x.

1.) 4x - 7 = 3

  • Add the like terms

4x = 3 + 7

  • Subtract 7 from each section

4x - 7 = 3

4x = 3 + 7

4x = 10

x = 10/4

x = 5/2

2.) 13 + 2x/3 = 15

(39 + 2x)/3 = 15

39 + 2x = 15 × 3

39 + 2x = 45

  • Subtract 45 from each term.

39 - 45 + 2x = 45 - 45

- 6 + 2x = 0

2x = 6

x = 6/2

x = 3

3.) 10x + 7 = 15

Subtract 15 from each terms

10x + 7 - 15 = 15 - 15

10x - 8 = 0

10x = 8

x = 8/10

x = 4/5

Answer:

1961

Step-by-step explanation:

circumference = 2\pi R\\157 = 2\pi R\\157 = 2\pi* R\\R = 157 / 2\pi \\\\area = \pi R^{2} \\area = \pi* (157 / 2\pi)^{2} \\area = \frac{24649}{4\pi} \\area = 1961 \\

ok, I did smth wrong

I hope you can find error

mariarad [96]

Answer:

smallest is 3L

biggest is 12L

Step-by-step explanation:

here is what i got, i hope it helps!

Pail=4 glasses

Jug=3 glasses

Glass=1 glass

4+3+1=8glasses

24L÷8glasses= 3L in each glass

pail=12L (4×3)

jug=9L (3x3)

glass=3L (1×3)

12L+9L+3L=24L

The distance BC from Tower 2 to the plane will be 14,065.5 ft and the height of the plane from the ground will be 5,720.9 ft.

<h3>What is a right-angle triangle?</h3>

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

A plane is located at C on the diagram.

There are two towers located at A and B.

The distance between the towers is 7600 feet and angles of elevation are given.

Then in the right-angle triangle ΔADC, we have

\rm \tan 16 = \dfrac{H}{7600 + X}\\\\\\H = 0.2867(7600 +X)\\\\\\H = 0.2756\ X + 2179.2649 ...1

Then in the right-angle triangle ΔBDC, we have

\rm \tan24 = \dfrac{H}{ X}\\\\\\H = 0.4452\ X ...2

From equations 1 and 2, we have

0.4452X = 0.2756 X + 2179.2649

0.1696X = 2179.2649

            X = 12849.439 ≅ 12,849.4 ft

Then the distance BC from Tower 2 to the plane will be

\rm BC = \dfrac{12849.4}{\cos 24}\\\\\\BC = 14065.5 \ ft

Then the height of the plane from the ground will be

\rm H = 12849.4 \times  \tan 24 \\\\\\H = 5720.9 \ ft

The figure is shown below.

More about the right-angle triangle link is given below.
