Answer:
a/2=3
We simplify the equation to the form, which is simple to understand
a/2=3
We move all terms containing a to the left and all other terms to the right.
+ 0.5a=+3
We simplify left and right side of the equation.
+ 0.5a=+3
We divide both sides of the equation by 0.5 to get a.

C.

D.
$18.27
just show the letter
Answers
For the three types of candies, we will write a slope-intercept form equation. We know what m (slope) is for each equation, and there is no y-intercept because there is no starting point.
Equations:
Mints: y=.96x
Chocolates: y=4.70x
Lollipops: y=.07x
Using the given information, we can use the equations in function form. We know what x (input) is for all three types of candy, and that will give us y (output), which is the total for that candy type.
Solving:
Mints: y=.96(.75)
Chocolates: y=4.70(1.5)
Lollipops: y=.07(15)
We just input our information into the equations. Using logic, we know that we will have to multiply the cost of the candy by the number of candies to get the total of the three types.
Totals:
Mints: y=.72
Chocolates: y=7.05
Lollipops: y=1.05.
*Recall that y=total cost of candy for each type.
Now, we just simply add the three costs up to get the total sum that the candy will cost:
.72+7.05+1.05=8.82
Therefore, all the candy will cost $8.82.

Explain.
Answers
Answer:
No, she tipped about 18%.
Step-by-step explanation:
How much she tipped:
$25 - $21.18 = $3.82
To find the percentage, you can put this tip over the what she paid for the pizza.
[tex]\frac{3.82}{21.18} =0.18=18%[/tex]%
She only tipped about 18%
Jalen made $533.75 while working at his job. He makes $15.25 an hour, how many hours did he work to make that amount of money?
Answers
Answer:
35 hours
Step-by-step explanation:
Typically, people get their paycheck after 2 weeks.
Let say he worked 8 hours a day, a typical amount of hours for the average human who has a occupation.
Multiply the amount of hours by the amount payed every hour.
So 15.25 x 8 is 122
( so in 8 hours jalen made $122)
Add 8 hours, which would now be 16 hours worked.
16 x 15.25 = 244
(so in 16 hours jalen made $244)
Add another 8 hours of work time which would now be 24 hours (1 full day)
24x5.25=366
Add 10 hours on now which would be 34 hours worked (2 days = 48 hours meaning she worked 1 day and 10 hours )
34x15.25=518.50
(getting closer to the amount she earned)
So if we add another hour
which would be 35 hours worked (1 day 11 hours)
35 x 15.25 = 533.75
Therefore, Jalen worked 35 hours.

Katie bought 4 sweaters that each cost the same amount and 1 skirt that cost $20. The items she bought cost a total of $160 before tax was added. What was the cost of each sweat?
Answers
Answer:
$35
Step-by-step explanation:
first we need to find the amount of money the sweaters cost alone.
so we first subtract the total (160) - the skirt price (20) which is 140
now we divide it by 4 to find the price of each seater, as they all cost the same.
so 140 divided by 4 = 35
answer: $35

A company rents out 19 food booths and 20 game booths at the county fair. The fee for a food booth is $200 plus $7 per day. The fee for a game booth is $65 plus $5 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
Answers
Answer:
$2715
Step-by-step explanation:
Given that 15 food booths were rented out for ‘d’ days at $100 plus $5 per day. On the food booths only, the company will earn 15($100+$5d) = $1500 + $75d Given that 20 game booths were rented out for ‘d’ days at $50 plus $7 per day. On the game booths only, the company will earn 20($50 + $7d) = $1000 + $140d
The total amount that the company is paid is therefore, $1500 + $75d + $1000 + $140d = $2500 + $215d

Answer:
f(6) = -7
Step-by-step explanation:
It is given that x = 6. Plug in 6 for x in the given equation:
f(x) = -x - 1
f(6) = -(6) - 1
Note that when you are subtracting two negative numbers, you are really adding the two numbers:
f(6) = -(6) - 1
f(6) = -7
When x = 6, f(x) = -7
