Answer:

Step-by-step explanation:

12(6) + 1/4 • 2^2

Square the 2 first.

12(6) + 1/4 • 4

Then multiply from left to right.

72 + 1

Lastly, add.

The parenthesis around the 6 mean multiplication, not the Parenthesis that are grouping symbols if you are learning PEMDAS. So your question has no grouping symbol parenthesis. Next comes Exponents, that's why we squared the 2. Multiply and Divide come next IN THE ORDER THAT THEY APPEAR FROM LEFT TO RIGHT. Then the same method with adding and subtracting. That's called the order of operations.

I NEED HELP WITH THIS PLEASE HELP ME

Answer:

156 minutes

Step-by-step explanation:

So we need to create an equation to represent how Frank's phone company bills him

I will denote "y" as the total for his bill
I will denote "x" as the number of minutes Frank uses

So the phone company charges an $8 monthly fee, so this value remains constant and will be our "y-intercept"

They then charge $0.06 for every minute he talks, this will be our "slope"

Combining everything into an equation, we have: y = 0.06x + 8

Now since we were given Franks phone bill total and want to figure out how many minutes he used, we just need to solve the equation for x and plug in our known y value

y = 0.06x + 8 → y - 8 = 0.06x → $x=\frac{y-8}{0.06}$
Then plugging in our y value we get $x=\frac{17.36-8}{0.06}=\frac{9.36}{0.06}= 156$

Frank used up a total of 156 minutes

Does anyone understand?

so, Buttons Etc. sells buttons at $50 + 1.10 for each button, and Logos sells buttons fro $40 + 1.10 for each button.

let's say that "b" is the amount of buttons Crusader Pep Club is going to buy.

let's take a look at a few buttons prices for Buttons Etc.

1 button.................. 50 + 1.10(1)

2 buttons............... 50 + 1.10(2)

3 buttons............... 50 + 1.10(2)

4 buttons............... 50 + 1.10(4)

5 buttons............... 50 + 1.10(5)

b buttons............... 50 + 1.10(b)

let's take a look at the prices at Logos

1 button.................. 40 + 1.10(1)

2 buttons............... 40 + 1.10(2)

3 buttons............... 40 + 1.10(2)

4 buttons............... 40 + 1.10(4)

5 buttons............... 40 + 1.10(5)

b buttons............... 40 + 1.10(b)

when both companies are the same price, the price equation for Buttons Etc equals the price equation for Logos, namely 50+1.10b = 40 + 1.10b.

when does that occur? At how many buttons?

50+1.10b = 40 + 1.10b

10 ≠ 0

from the system of equations, we end up with 10 = 0, which is not true of course 10 ≠ 0, which is another way to say there's no solution to the system, namely, the equations' graphs never touch each other.

if you recall the slope-intercept form, notice, both have the same slope, so the lines are parallel, and the y-intercept differs, so they never touch each other.

so, since there's no solution, the companies Buttons Etc and Logos sales of buttons will never yield the same price, the prices will always differ for the same amount of buttons sold.
