18 is equal to 3 times the sum of two and a number. What is the number?

1st rectangle and 4th rectangle

Answer:

3, 15

Step-by-step explanation:

1/10 of a unit also just means dividing by 10. 1/2 is just dividing by 2. Hope this helped!

Answer:

1/10= 3

1/2=15

Step-by-step explanation:

If the whole unit is 30, then one tenth of it would be three (3x10=30) and one half of it would be 15 (2x15=30)

In technical terms, the slope of the line is the change in y over the change in x. But I just like to think of it as rise over run. To find the slope of the line, pick two points on the line

Answer:

X=0

Step-by-step explanation:

[tex]8(1 \times 5x) + 5 = 13 + 5x \\ 8 + 40x + 5 = 13 + 5x \\ 40x + 13 = 13 + 5x \\ 40x - 5x = 13 - 13 \\ 35x = 0 \\ x = 35 \times 0 \\ x = 0[/tex]

The solution to the equation is x = 0.

Here, we have,

Let's solve the equation step by step:

Distribute the 8 to the terms inside the parentheses:

8 + 40x + 5 = 13 + 5x

Combine like terms on both sides of the equation:

40x + 13 = 5x + 13

Subtract 5x from both sides to isolate the variable terms on one side:

40x - 5x + 13 = 5x - 5x + 13

Simplifying:

35x + 13 = 13

Subtract 13 from both sides to isolate the variable term:

35x + 13 - 13 = 13 - 13

Simplifying:

35x = 0

Divide both sides of the equation by 35 to solve for x:

35x/35 = 0/35

Simplifying:

x = 0

Therefore, the solution to the equation is x = 0.

Answer:

16.5 : 38.5

Step-by-step explanation:

sum the parts of the ratio, 3 + 7 = 10 parts

Divide the amount by 10 to find the value of one part of the ratio.

55 ÷ 10 = 5.5 ← value of 1 part of the ratio, then

3 parts = 3 × 5.5 = 16.5

7 parts = 7 × 5.5 = 38.5

55 in the ratio 3 : 7 is 16.5 : 38.5

Answer:

equation: 3.5x=31.5

number of hours: 9

Step-by-step explanation:

31.5/3.5=9

Therefore,

x=9, x=number of hours, number of hours=9

2. the picture is cut off

Answer:

A system of equations are two or more equations that has to be valid at the same time. It means that the variables of one equation can be substitute in the other equation.

For example we have y=5x−8 and we can substitute this value of y in the other equation

4x+3y=33

4x+3(5x−8)=33 we can solve now for x

4x+15x−24=33

19x=33+24

19x=57

x=5719=3.

y can be obtained from the first equation

y=5x−8

y=5⋅3−8=15−8=7

Then x=3 and y=7.

Step-by-step explanation:

Answer:

x = 3

y = 7

Step-by-step explanation:

y = 5x - 8  ---------------(I)

4x + 3y = 33 ------------(II)

Substitute y = 5x - 8 in equation (II)

4x + 3 (5x - 8) = 33  

4x + 3*5x - 8*3 = 33

4x + 15x - 24 = 33           {Combine like terms}

      19x  - 24 = 33            {Add 24 to both sides}

            19x = 33 + 24

           19x = 57           {Divide both sides by 19}

             x = 57/19

x = 3

Substitute x = 3 in equation (I)

y = 5*3 - 8

y = 15 - 8

y = 7

Given

[tex]Expression = 40\% * 75[/tex]

[tex]Priya = \frac{2}{5} * 75[/tex]

Required

Is Priya correct?

We start by simplifying the expression.

[tex]Expression = 40\% * 75[/tex]

Express 40% as fraction

[tex]Expression = \frac{40}{100} * 75[/tex]

Simplify fraction: Divide numerator and denominator by 20

[tex]Expression = \frac{40/20}{100/20} * 75[/tex]

[tex]Expression = \frac{2}{5} * 75[/tex]

By comparing:

[tex]Expression = \frac{2}{5} * 75[/tex]

and

[tex]Priya = \frac{2}{5} * 75[/tex]

We can conclude that Priya is correct because:
