Answer:
one ticket is $1.20
Step-by-step explanation:
6 / 5 = 1.2, then check it by multiplying 1.2 x 5. Its easier than you think. Im positive im correct. All you have to do is one but if u want to make sure you can do all of them
Let's call:
a = price of 1 apple
p = price of 1 peach
The total cost is the price of 1 apple times the number of apples plus the price of 1 peach times the number of peaches, therefore the system can be:

Solve for a in the second equation (you can choose to solve for any of the variables in any of the equations, try to understand what is the best):
a = (4.82 - 5p) / 4
Now, substitute in the first equation:
6 · (4.82 - 5p) / 4 + 9p = 7.86
7.23 - (15/2)p + 9p = 7.86
(3/2)p = 0.63
p = 0.42
Now, substitute this value in the formula found for a:
<span>a = (4.82 - 5·0.42) / 4</span>
= 0.68
Therefore, one apple costs
0.68$ and one peach costs
0.42$.
Answer:
1.83 hours
Step-by-step explanation:
Time is inversely proportional to speed
Implies that T = k/R, where k is the constant of proportionality
Thus, the product T × R is a constant for any given valued of R,T.
Hence, 3 × 14 = t × 23
t = (3×14) ÷ 23
t = 1.83 hours
Answer:
The answer to your question is ( -7/10, -4 7/10)
Step-by-step explanation:
Data
Enpoint (3/2, 1 1/2) x1 = 3/2 y1 = 1 1/2
Midpoint (2/5, -8/5) xm = 2/5 ym = -8/5
Entpoint 2 ( x, y)
Formula
Xm = (x1 + x2)/2 Solve for x2 x2 = 2xm - x1
Ym = (y1 + y2)/2 Solve for y2 y2 = 2ym - y1
Substitution
x2 = 2(2/5) - 3/2
x2 = 4/5 - 3/2
x2 = (8 - 15)/10
x2 = -7/10
y2 = 2(-8/5) - 1 1/2
y2 = -16/5 - 3/2
y2 = (-32 - 15) / 10
y2 = -47/10 = -4 7/10
