Answers
The answer is 26
Here is the process:
1. Replace the variables with the numbers they gave you.
2(-9)+ (-9)(-5)+ 2-3
2. Next evaluate it. I got 45 because a negative multiplied by a negative makes a positive.

A small bus charges $3.50 per person for a ride from the train station to a concert. The bus will run if at least 3 people take it, and it cannot fit more than 10 people. Function B gives the amount of money that the bus operator earns when n people ride the bus.
Answers
The minimum amount of money that the operator earns when n people ride the bus is $10.5 and the maximum amount of money that the operator earns when n people ride the bus is $35.
A small bus charges $3.50 per person for a ride from the train station to a concert.
The maximum capacity of the bus to carry the passengers is 10.
The minimum capacity of the bus to carry the passengers is 3.
Function B gives the amount of money that the bus operator earns when n people ride the bus.
Thus the value of 'n' is restricted between 3 to 10.
Therefore,
In general, the amount of money that the operator earns when n people ride the bus is given by the expression.
[tex]\rm{Amount}= \$3.5n[/tex]
The above amount can have minimum and maximum values.
Thus, the minimum amount of money that the operator earns when n people ride the bus is $10.5 and the maximum amount of money that the operator earns when n people ride the bus is $35.

What is the value of y in the equation 5x + 2y = 20, when x = 0.3?
Answers
Answer:
9.25
Step-by-step explanation:
5(0.3) = 1.5
20-1.5=18.5
18.5÷2=9.25
Answer:
y = 9.25Step-by-step explanation:
5x + 2y = 20
when x = 0.3 we have
5(0.3) + 2y = 20
1.5 + 2y = 20
Using the subtraction property subtract 1.5 from both sides of the equation
That's
1.5 - 1.5 + 2y = 20 - 1.5
2y = 18.5
Divide both sides by 2
[tex] \frac{2y}{2} = \frac{18.5}{2} [/tex]
We have the final answer as
y = 9.25Hope this helps you

The local coffee house reported losses of -⅜ of their normal profit each day for 3 days. If their normal profit is $350 a day how much money was lost for the 3 days?
Answers
Answer:
Total loss in three days = $393.75
Step-by-step explanation:
Given:
Loss amount = [-3/8] of normal profit
Normal profit per day = $350
Find:
Total loss in three days
Computation:
Total loss in three days = 3 [Normal profit per day][Loss amount]
Total loss in three days = 3 [350][3/8]
Total loss in three days = 3[131.25]
Total loss in three days = $393.75

Negative x Positive = Negative
Positive x Negative = Negative
Negative x Negative = Positive
Positive x Positive = Positive
2) Since -5 and -8 are both positive numbers, the answer will be a positive product:

Answers
Answer:
[tex]f=\frac{9c}{5}+32[/tex]
Step-by-step explanation:
[tex]c=\frac{5\left(f-32\right)}{9}[/tex]
Switch sides:
[tex]\frac{5\left(f-32\right)}{9}=c[/tex]
Multiply both sides by 9:
[tex]\frac{9\times5\left(f-32\right)}{9}=9c[/tex]
[tex]5\left(f-32\right)=9c[/tex]
Divide both sides by 5:
[tex]\frac{5\left(f-32\right)}{5}=\frac{9c}{5}[/tex]
[tex]f-32=\frac{9c}{5}[/tex]
Add 32 to both sides:
[tex]f-32+32=\frac{9c}{5}+32[/tex]

PEMDAS is the order of operation, and =
Parenthesis
Exponents (& Roots)

Subtract 67 from both sides of the equation:
k + 67 = 83
k + 67 (-67) = 83 (-67)
k = 83 - 67
k = 16
16 is your answer for k.
