Answer:

x = -3 and x = -11

Step-by-step explanation:

Find the "bare" absolute value function, then solve the two resulting equations.

2|x+7| -3 = 5

2|x +7| = 8 . . . . . add 3

|x +7| = 4 . . . . . . divide by 2

This resolves to two equations:

x +7 = 4

x = -3 . . . . . subtract 7

and

x +7 = -4

x = -11 . . . . . subtract 7

The two solutions are ...

x = -3 and x = -11

Write a equation for 10 less than j is 35

kakasveta [241]

Answer:

$j - 10 = 35$

Step-by-step explanation:

Given: 10 less than $j$ is 35.

To find: The equation of the given situation.

Solution: We need to write an equation for 10 less than $j$ is 35.

Here, we will break down the sentence to form the equation.

10 less than $j$ means $j - 10$ .

Then, it says 10 less than $j$ is 35 which means it is equal to 35.

So, the sentence 10 less than $j$ is 35 can be written as 10 less than $j$ is equal to 35.

Now, 10 less than $j$ is equal to 35 can be shown as $j - 10 = 35$ .

Therefore, the required equation is $j - 10 = 35$ .

Two number are in the ratio 5:6 and their sum is 44 .Use z as variable

Mariulka [41]

Answer:

the numbers are 20 and 24

Step-by-step explanation:

The numbers are in the ratio 5 : 6 = 5z : 6z , where z is a multiplier

The numbers sum to 44, thus

5z + 6z = 44

11z = 44 ( divide both sides by 11 )

z = 4

Hence

5z = 5 × 4 = 20

6z = 6 × 4 = 24

The two numbers are 20 and 24
