Answer:
94 pizzas will be sold
Step-by-step explanation:
We have to use the equation and replace 15 with x.
x=15
y=3.4x + 43
y=3.4(15) + 43
y=51 + 43
y=94
(15,94)
There will be 94 pizzas sold nightly if 15 coupons were issued.
Answer:
21/41
Step-by-step explanation:
Find the total number of students
6+7+2+3+6+8+4+5=41
Then find the students that do not study chemistry
6+7+2+5 = 20
P( not study chemistry) = do not study chem)/total
=21/41
Answer:
The purchase price is $180
The total price is: $189
Step-by-step explanation:
Sales tax rate = 5\%
Sales tax on bike = $9
We need to find the purchase price.
Let purchase price = x
We know that Sales tax = 5% of x
and Total price = Purchase Price + Sales tax
So, we can write:
Sales tax = 5% of x
Putting values and finding x
![9 =5\% \:of\: x\\9=\frac{5}{100}\:of\:x \\x= \frac{9*100}{5}\\x=180](https://tex.z-dn.net/?f=9%20%3D5%5C%25%20%5C%3Aof%5C%3A%20x%5C%5C9%3D%5Cfrac%7B5%7D%7B100%7D%5C%3Aof%5C%3Ax%20%5C%5Cx%3D%20%5Cfrac%7B9%2A100%7D%7B5%7D%5C%5Cx%3D180)
So, the value of x i.e Purchase price = $180
The purchase price is $180
Now finding the total price of bicycle
Total price = Purchase Price + Sales tax
Total price = 180 + 9
Total price = $189
So, The total price is: $189
Answer:
The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation.
So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation. And since x + y = 8, you are adding the same value to each side of the first equation.
