Y- y1 = m (x-x1)
y+1 = 4(x+3)
y+1=4x+12
y=4x+11
Answer:
(A) 6%
(B) 57%
(C) 357%
(D) 100%
Step-by-step explanation:
(A) 6 / 100 = 6%
(B) 57 / 100 = 57%
(C) 357 / 100 = 357%
(D) 100 / 100 = 100%
Answer:
x = 16
∠A = 39
∠B = 54
∠C = 87
Step-by-step explanation:
Make a equation of all of the angles added together is equal to 180 since the angles of a triangle added together is 180
(4x-10)+(2x+7)+(7x-25)=180
combine like terms
4x+2x+7x-10+7-25 = 180
13x-28=180
solve for x
13x=208
x = 16
plug in x to find the measure of the angle
∠A = 2(16) + 7 = 39
∠B = 4(16) - 10 = 54
∠C = 7(16) - 25 = 87
Add them together to double check your answer
39 + 54 + 87 = 180
hope this helps
Let the number be represented by x
2x=60+ 5x -20*2=60+5*-20
2x-5x=5x-5x+60 -40=60+-100
-3x=60 -40=-40
-3x/-3=60/-3
x=-20
Therefore the number is -20
