Subtract the monthly fee from the total, then divide by the price of each session.
125 - 15 = 110
110 / 13.75 = 8
She got 8 sessions.
7+7+3+3= 20
The answer would be
The perimeter of the fabric she cut out would be 20 cm.
Answer:
36º
Step-by-step explanation:
The sum of a triangle's angles is 180. So, 6x+2x+2x=180. And, 10x=180, and then x=18. Angle C is 2x. To find angle C multiple 18 by 2 to get 36.
Find the gradient:
m = y2-y1 / x2-x1
m = 6-(-4) / 0-1
m = 10 / -1
m = -10
Slope intercept form:
y = mx + c
Input the values from one of the points to find c (imputing (1,-4) to y=mx+c):
-4 = -10(1) + c
-4 = -10 + c
c = -4 + 10
c = 6
Therefore, the equation is:
y = -10x + 6
