Answer:
X=36
Step-by-step explanation:
3x+72=180
3x=180-72
3x=108
x=36
Measure of z is 116°.The measure of y is 48°.Hope this helps.
Answer:
(3, 1)
Step-by-step explanation:
(a) Algebraic solution
(1) y = -⅔x + 3
(2) y = 2x - 5
Set Equation (1) equal to Equation (2)
-⅔x + 3 = 2x - 5
Multiply each side by 3
-2x + 9 = 6x - 15
Add 15 to each side
-2x + 24 = 6x
Add 2x to each side
24 = 8x
Divide each side by 3
(3) x = 3
Substitute (3) into (2)
y = 2×3 - 5 = 6 - 5 = 1
The ordered pair that makes both equations true is (3, 1).
(b) Graphical solution
In the diagram below, the red line is the graph of Equation (1). The blue line is the graph of Equation (2). The point of intersection is at (3, 1).
Answer: 11.65 Answer: The area of a cube = side x side x side or side^3. So all you need to do is take the cubed root of 1582.56 which is approximately 11.65
Answer:x=13
BMC=75 degrees
Step-by-step explanation:
(x+2)+(5x+10)=90 degrees
so 6x+12=90
x=13
5x+10=5x13+10=75 degrees
