can someone help me solve 70 < 3x + 10 < 100

Answer:

x = 9/2

Step-by-step explanation:

6x - 8 = 4(x + 2) - 7

Distribute on the right side.

6x - 8 = 4x + 8 - 7

Combine like terms on the right side.

6x - 8 = 4x + 1

Add 8 to both sides. Subtract 4x from both sides.

2x = 9

Divide both sides by 2.

x = 9/2

Answer:

m<2 = 65

Step-by-step explanation:

The measures of angles 1 and 3 should be added together resulting in 115 degrees, and all triangles equal 180 degrees. Therefore, to find m<2, you have to subtract 115 from 180 resulting in a measure of 65 degrees.

Answer:

2) is addition property

3) is multiplication property

Step-by-step explanation:

The addition property and division properties are used to solve the inequality.

A relationship between two expressions or values that are not equal to each other is called 'inequality.

The given inequality is  3x – 2 > -4.

Three times of x minus two is greater than minus four

By using addition property we add +2 on both the sides

3x – 2 +2 > -4+2

3x>-2

By using division property we divide  +3 on both the sides

x>-2/3

Hence, the addition property and division propertys are used to solve the inequality.

Answer:

The number is 15

Step-by-step explanation:

1/3(number) + 25 = 2(number)

subtract 1/3(number) from each side

25 = 2(number) - 1/3(number)

25 = 6/3(number) - 1/3(number)

25 = 5/3(number)

multiple each side by 3/5, which is the reciprocal of 5/3

25(3/5) = number

15 = number

Answer:

21 slices

Step-by-step explanation:

given:

3/7 of a pizza ----> represents 9 slices

hence,

1/7 of a pizza -------> represents 9/3 = 3 slices

therefore

a whole pizza

= 7/7 of a pizza -------> represents 3 x 7 = 21 slices

Answer:

Hi there!!

Your answer is:

21 slices

Step-by-step explanation:

3/7ths = 9 slices

× 7/3

1 whole pizza = 21 slices

This is called the multiplicative inverse! 3/7 × 7/3 = 1

x = 2

Step-by-step explanation:

So we are given the equation 14x - 10 = 3(4 + x) and we are asked to solve for x. To this, we will have to get x by itself on one side and a value on the other side.

14x - 10 = 3(4 + x)

Distribute the 3 on the right side.

14x - 10 = 12 + 3x

Add 10 to both sides.

14x = 22 + 3x

Subtract 3x from both sides.

11x = 22

Divide both sides by 11.

x = 2

So now we got the answer of x = 2.

I hope you find my answer helpful.

Answer:

x = 2

Step-by-step explanation:

14x - 10 = 3(4+x)

=> 14x -10 = 12 + 3x

=> 14x - 3x = 12 + 10

=> 11x = 22

=> x = 22/11

=> x = 2

Solution.

Step-by-step explanation:

The value of x in the given expression is -a/6

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given is an expression, 4 = 6x / a + 5

Solving for x, we get,

4 = 6x / a + 5

Subtracting 5 both the side,

6x / a = -1

Multiplying by a both the sides,

6x = -a

Dividing by 6 both sides,

x = -a/6

Hence, the value of x is -a/6

  left limit = 2 ≠ 1/2 = right limit

Step-by-step explanation:

A function is discontinuous if the limit of the function value approaching the point from the left is different than the limit approaching from the right.

Here, the left limit is 2 and the right limit is 1/2. The limits are different, which is why the function is discontinuous at x=-1.
