What is the answer to 1/7(x+3/4)=1/8
ivolga24 [154]

Answer:

<h3>x = 1/8</h3>

Step-by-step explanation:

1/7(x+3/4) = 1/8

Multiply 1/7 with x and 3/4

1/7x + 3/28 = 1/8

Multiply everything by 7, so x is a whole number

x + 21/28 = 7/8

Convert 21/28 into a similar like denominator to 7/8

x + 6/8 = 7/8

x = 7/8 -6/8

x = 1/8

Which values are solutions to the inequality –3x – 4 &lt; 2? Check all of the boxes that apply.
luda_lava [24]

Answer:

x>-2

Step-by-step explanation:

We will need to solve the inequality:

–3x – 4 < 2

Before starting we need to understand 1 rule of inequalities. That is:

We change the inequality sign whenever we multiply or divide by a negative number. That means

< changes to >

and

≥  change  to ≤

and vice versa...

Now, let's go ahead and solve the inequality:

-3x-4

"x" is the set of all values that is greater than "-2". So that's the answer.

x > -2

Answer:

x = 47

Step-by-step explanation:

So It most likely adds up to 180 degrees so.

x + 10 + x -10 + x - 10 + x + 6 = 180 (collect like terms)

4x -4 = 184 ( add 4 on both sides)

4x = 188 (divide 188 by 4)

x = 47

47 + 10 = 57 ----> x + 10

47 - 10 = 37 -----> x - 10

47 + 6 = 53 ------> x + 6
