Answer: 55
Step-by-step explanation:
90+35=125
180 is the total degrees of an angle so 180-125= 55
For 20% out of 100% it would be 1/5 as you need 5 20s for 100
Answer:
see below
Step-by-step explanation:
x - 2/5= 7
Add 2/5 to each side
x - 2/5 + 2/5 = 7+2/5
x = 7 2/5
or if
( x-2) /5 = 7
Multiply each side by 5
(x-2) /5 *5 = 7*5
x-2 = 35
Add 2 to each side
x-2+2 = 35+2
x = 37
Y= 1/6 x + 7. To find a line that is perpendicular just take the slope and find the negative reciprocal. ex. A/B becomes -B/A. Hope this helped
4x^2 + 8x - 21 =
(2x - 3)(2x + 7) <==
