Answer:

x ≈ 4.3

Step-by-step explanation:

<em><u>Distribute the 4 to (8x - 3) and the 5 to (x - 5), like so:</u></em>

4(8x - 3) - 30x = 5(x - 5)

32x - 12 - 30x = 5x - 25

<u><em>Add like terms (32x and -30x), like so:</em></u>

32x - 30x = 2x

2x - 12 = 5x - 25

<em><u>Subtract 2x from both sides:</u></em>

2x - 12 = 5x - 25

-2x         -2x

____________

-12 = 3x - 25

<em><u>Add 25 to both sides:</u></em>

-12 = 3x - 25

+ 25       + 25

____________

13 = 3x

<em><u>Divide both sides by 3:</u></em>

4.3 ≈ x

Answer:

x = 13/3

Step-by-step explanation:

4(8x-3) - 30x = 5(x-5)

Distribute

32x - 12 - 30x  = 5x -25

Combine like terms

2x -12 = 5x-25

Subtract 2x from each side

2x-12-2x = 5x-2x -25

-12 = 3x-25

Add 25 to each side

-12+25 = 3x-25+25

13 = 3x

Divide each side by 3

13/3 = x

The part (aka "is") = 8 and the percent is 42, what is the whole (aka
marysya [2.9K]

Answer:

33

Step-by-step explanation:

If you simplify what the question is saying, it's basically..

8 is 24% of <u>what number?</u>

To find out, you can simply set up an equation.

((24% = 0.24 as a decimal (move the decimal point two times to the left))

8 = 0.24 x N (N is just the 'whole')

To solve, you just need to divide 8 ÷ 0.24. So, N = 33.333 repeating.

The question says to round to the nearest whole number, so the answer would just be 33.

Myra has a remote-controlled toy boat. She runs the toy boat on a lake at a constant speed. The graph of a function representing
lawyer [7]

The coefficients of the linear equation are:

  • Rate of change = 4.2
  • Initial value = 3.8

This means that the correct options are B and E.

<h3><u>How we can find the linear equation?</u></h3>

First, a general linear equation is written as:

y = a*x + b

Where a is the rate of change (also called slope) and b is the y-intercept (also called initial value).

If we know that the line passes through two points (x₁, y₁) and (x₂, y₂), then the rate of change is given by:

a = \frac{y_2 - y_1}{x_2 - x_1}

In this case, we know that the line passes through:

(1, 8) and (1.5 , 10.1)

Then the rate of change is:

a = \frac{10.1 - 8}{1.5 - 1}  = 4.2

So the line is something of the form:

y = 4.2*x + b

To find the value of b we can use one of the given points, I will use (1, 8).

This means that when x =1, we have y = 8, replacing that we get:

8 = 4.2*1 + b

8 - 4.2 = b

3.8 = b

So we have:

  • Rate of change = 4.2
  • Initial value = 3.8

Then the correct options are:

B and E.
