All the interior angles of a triangle always add up to 180 degrees.
3x + (2x + 20) + (4x - 20) = 180
3x + 2x + 20 + 4x - 20 = 180
3x + 2x + 4x + 20 - 20 = 180
10x = 180
x = 180/10
Therefore, x = 18
Answer:
The answer would be A)98.
I got this by taking the 3 test scores that were provided and adding them then subtracting that by 360 (90x4 - which would give you a 90 in the end) so I had 360 - 262 which equaled 98 and that would be the score needed to have a 90 in the end.
Answer:
A) Hertz: 42x+32=y
Enterprise: y=46x+24
B) Hertz is less by 16 $; 300$ minus 386$
C)16$
D) 9$
Step-by-step explanation:
Answer:
x < 31?
Step-by-step explanation:
Given the inequality: x-8 < 23, you must add 8 to 23 to isolate the variable. So...
x - 8 < 23
x < 31
Answer:(-3,-8),(-6,4),(1,-1)
Step-by-step explanation:
Given
Vertices of the triangle are
Coordinates (a,b) when reflected about x-axis is given as (a,-b) i.e. Y coordinate changes its sign
