5 more than 3 times a variable, x, is 23
Monica [59]

3x + 5 = 23

5 more than(addition) 3 times(multiplication) a variable(x) is(equals) 23

(you add 5 to 3x)

If you need to solve for "x", you need to isolate/get the variable "x" by itself in the equation:

3x + 5 = 23        Subtract 5 on both sides

3x + 5 - 5 = 23 - 5

3x = 18      Divide 3 on both sides to get "x" by itself

\frac{3x}{3} =\frac{18}{3}

x = 6

Point S is on line segment RT. Given RS = 4x – 10, ST = 2x – 10, and
borishaifa [10]

Answer:

The numerical length of RS is 22 units

Step-by-step explanation:

∵ Point S is on the line segment RT

→ <em>That means S divide RT into two parts RS and ST</em>

∴ RS + ST = RT

∵ RS = 4x - 10

∵ ST = 2x - 10

∵ RT = 4x - 4

→ <em>Substitute them in the statement above</em>

∴ 4x - 10 + 2x - 10 = 4x - 4

→ <em>Add the like terms in the left side</em>

∴ (4x + 2x) + (-10 + -10) = 4x - 4

∴ 6x + (-20) = 4x - 4

∴ 6x - 20 = 4x - 4

→ <em>Add 20 to both sides</em>

∴ 6x -20 + 20 = 4x - 4 + 20

∴ 6x = 4x + 16

→ <em>Subtract 4x from both sides</em>

∴ 6x - 4x = 4x - 4x + 16

∴ 2x = 16

→ <em>Divide both sides by 2 to find x</em>

∴ \frac{2x}{2}=\frac{16}{2}

∴ x = 8

→ <em>Substitute the value of x in Rs to find its length</em>

∵ RS = 4(8) - 10

∴ RS = 32 - 10

∴ RS = 22 units

The numerical length of RS is 22 units

Write equivalent expressions of 18m+42n​
serious [3.7K]

Answer:

See explanation

Step-by-step explanation:

Given:

18m + 42n

These two variables are not the same, so we can't add the two terms. However, we can factor out a number out of this expression.

The GCF of 18 and 42 is 6.

We can draw 6 out of this expression to get 6(3m + 7n).

This is an equivalent expression.

We can also draw 2 out to get 2(9m + 21n).

We can also draw 3 out to get 3(6m + 14n).

We can also draw 1/2 out to get (1/2)(36m + 84n).

There are endless possibilities, but these are a few. You get the idea!

Please mark as Brainliest! :)
