Answer:
11
Step-by-step explanation:
30-2(7+2)-1
PEMDAS says parentheses first
30-2(9)-1
Then multiply
30 -18 -1
Then subtract
12-1

Answer:
A) 8+2.50x=28
B) 8 rides
C) Jada can go on 8 rides before she has spent all of her money
Step-by-step explanation:
subtract the $8 fee from 28 and get 20, then divide 20 by how much each ride costs (2.50) and get 8 :)
First, let's find the slope.
Slope = (7 - (-3)) / (2 - 0) = (7 + 3) / 2 = 10 / 2 = 5
So far our equation looks like: y = 5x + b
Leta plug one of the points into our equation to find b.
-3 = 5(0) + b
Simplify.
-3 = b
The equation is: y = 5x - 3
Answer choice B is correct.
-2=-1/6(3)+b
-2=-0.5+b
-1.5+b
y=-1/6 -0.5
Step-by-step explanation:
In figure:
∠PRT+∠RTP+∠TPR=180
