Answer: If you were to graph the solution it would be evident. One solution is when the lines meet at one point, no solution is when the lines are parallel to each other (they do not touch) and infinitely solutions happens when the two lines are on top of each other.
Step-by-step explanation:
Answer:
B. 2x + x = 90°
Step-by-step explanation:
A right angle is equal to 90 degrees. This line appears to be splitting a right angle, so adding both should equal 90 degrees.
Given the figure of a triangle
The shown is a regular triangle,
Answer:
1n - 6 is the algebraic expression for six less than the product of 11 and a number
Answer:
a = 9
Step-by-step explanation:
45 = 4(a + 3) – 3
Add 3 to both sides.
48 = 4(a + 3)
Divide both sides by 4.
12 = a + 3
Subtract 3 from both sides.
9 = a
a = 9
Answer: a = 9
