Answer: x ≤ 7

Step-by-step explanastion: 7x-50≤ -1 and -6x +70> -2

Solve separately and then put back together

7x-50≤ -1

Add 50 to each side

7x-50+50≤ -1+50

7x ≤ 49

Divide each side by 7

7x/7 ≤ 49/7

x ≤ 7

-6x +70> -2

Subtract 70 from each side

-6x +70-70> -2-70

-6x> -72

Divide by -6, remembering to flip the inequality

-6x/-6 < -72/-6

x < 12

The first is more restrictive, and since it is an and, we use the more restrictive answer

Given the diagram below, what is m/B?

Radda [10]

Answer:

115°

Step-by-step explanation:

The above shape is a quadrilateral.

A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles.

The sum of interior angles of a Quadrilateral is 360°

Therefore,

115 + 65 + 65 + m = 360

245 + m = 360

m = 360 - 245

m = 115°

Therefore, m< B = 115°
