The angles of a triangle add up to 180 degrees
65 + 3x - 10 + 2x = 180
5x + 55 = 180
5x = 180 - 55
5x = 125
x = 125/5
x = 25 <====
m < B = 3x - 10 = 3(25) - 10 = 75 - 10 = 65 <== B is 65 degrees
m < C = 2x......= 2(25) = 50 <== C is 50
Answer:
a) 30%
b) 280
Step-by-step explanation:
a) 3/10 = 30/100 = 30%
b) 30% = 0.3
0.3 × 400 = 120
400 - 120 = 280
Answer:
C. m ≥ 9
Step-by-step explanation:
7m -2 ≥ 61
7m ≥ 61+2
7m ≥ 63
m ≥ 63/7
m ≥ 9
Answer:
Undefined
Step-by-step explanation:
The slope on the graph is horizontal so there's no slope and the answer is just y = 3
For a line to be perpendicular to a horizontal line, it is going to be a vertical line.
All vertical lines have an undefined slope.
1) 475
2)375
You need to multiply 25 by 27 and you get 675 then to get answer one you need to multiply 10 by 20 to get 200 the take 200 away from 675 to get 475 then do the same thing with the second problem 20x15 which is 300 the take 300 away from 675.
