Answer:

3x + 9 = 21

Step-by-step explanation:

Let Henry's age be x

Mary's age = 9 + 3x

21 = 9 + 3x

Can also be written as 3x + 9 = 21

What digits can be in the ones place on a number that has 5 as a factor
jek_recluse [69]
If five is a factor, it means that number can be evenly divided by five. Think about it like you're counting by fives or doing the fives times tables.

5, 10, 15, 20, 25, 30, 35, 40, 45, 50 etc.

As you can see, the only numbers that are in the ones place are 5 and 0.

Hope that helps!

2x+4y=-8 what the x intercept
Ganezh [65]
<h3><u>The x intercept is -4.</u></h3>

To find the x intercept, all we need to do is replace the value of y with 0.

2x + 4(0) = -8

Solve for x.

2x = -8

Divide both sides by 2.

x = -4.

Here is a 5 by 8 grid
Ksivusya [100]

On solving the linear equation, There are in total 24 unshaded squares and 16 shaded squares.

<h3>What is a linear equation?</h3>

Ax+By=C is the usual form for two-variable linear equations. A typical form linear equation is, for instance, 2x+3y=5. When an equation is provided in this format, finding both intercepts is rather simple (x and y).

squares, where x= number of squares

2x = shaded squares

Number of unshaded squares = 3x.

This is due to the fact that there are 3 times as many unshaded squares as there are shaded squares (2 times more unshaded = 3*). (shaded)

Overall, there are 40 squares (5 * 8), therefore 40 total squares—shaded and unshaded—are present.

2x+3x = 40

5x = 40

x = 40/5

x = 8

There are 3×8 = 24 unshaded squares

8×2 = 16 shaded squares in all.

Therefore, you may shade in 8 squares whatever you choose.

109.5

Step-by-step explanation:

Ⓗⓘ ⓣⓗⓔⓡⓔ

:

9.5x5x0.5

:

Volume would be 9.5*5*0.5=23.75

:

2wl+2lh+2hw

2(5*9.5)+2(9.5*0.5)+2(0.5*5)=95+9.5+5=109.5
