Answer:
Step-by-step explanation:
x = last month
y = this month
y = 2x + 7
y = 43
43 = 2x + 7
43 - 7 = 2x
36 = 2x
36/2 = x
18 = x <== he sold 18 gym memberships last month
Answer:The volume of the cube is 1/2 x 1/2 x 1/2 = 1/8
2646/(1/8) = 21168
Step-by-step explanation:
Answer:
y+z=x
Step-by-step explanation:
we know that
The <u>Exterior Angle Property of a Triangle</u> states that the measure of exterior angle of a triangle is equals to the sum of measures of its interior opposite angles
In this problem
Angle y and angle z are interior angles of triangle ABC and angle x is a exterior angle of triangle ABC
therefore
Applying the Exterior Angle Property of a Triangle
y+z=x

Step-by-step explanation:
To find the midpoint of a line use the midpoint formula which is M = (x1+x2/2 , y1 +y2/2) After plugging in the coordinates for your variables you should get (-1+5/2, -1+2/2) This simplifies to (2, 1/2) which is the coordinates for the middle point of the base XY.
