Answer:
The solution set is (4, 3)
Step-by-step explanation:
To solve by substitution, start by solving the second equation for y.
2x - y = 5
-y = -2x + 5
y = 2x - 5
Now that we have this, put that expression in for y in the first equation and solve for x.
5x - 2(2x - 5) = 14
5x - 4x + 10 = 14
x + 10 = 14
x = 4
Now that we have the value of x, input it into either equation and solve for y.
2x - y = 5
2(4) - y = 5
8 - y = 5
-y = -3
y = 3
Answer:
6 cm
Step-by-step explanation:
Volume of a prism= Length X Width x height
750 = 25 x 5 x h
750= 125h
750/125 = 125h/125
h= 6

Answer:
19 is 4/dc^2
21 is y+4/4
23 is x+2/x-2
Step-by-step explanation:
If x is the number of sides of the regular polygon, then the sum of the interior angles is (x - 2) * 180 = 56 * 90. Solving for x gives 30 for the number of sides of the regular polygon.
To get the central angles measure, divide 360 by 30 to get 12 degrees for the measure of one of the 30 central angles.
Answer: 12 degrees
