Answer:
A) $2.42, $2.33, $2.58
B) The best deal is 24 cupcakes for $56
Step-by-step explanation:
5r=75
r=75/5=15
3f=75
f=75/3
f=25
4d=75
d=75/4
d=18.9
5r+3d+4f+75
Answer: The first one is 144 . The second one is C.
Step-by-step explanation:
Answer: angle A=40, Angle B=74, Angle C=66
Step-by-step explanation:
We all know that a triangle has 180 degrees.
3x-8+5x-6+4x+2=180
12x-12=180
12x=180+12
12x=192
x=16.
∠A=2(16)+8=40
∠B= 90-16=74
∠C = 5(16) -14= 66
Answer:
-7x - 2
Step-by-step explanation:
First, find the new slope that is perpendicular.
1/7 -> 7 -> -7
So far, we have -7x + b. (we use mx + b)
Since you asked for it to pass point A (-1, 5), substitute in x and y.
y = -7x + b
5 = -7(-1) +b
5 = 7 + b
b = -2
So the equation would be -7x - 2.
Your welcome!
