(x - 9(a/8)) = a a = 16
Answer:
x = 34
Step-by-step explanation:
(x - 9(16/8)) = 16

Which choice correctly explains which product is the better buy? Coffee Brand A is sold for $6.99 per pound Coffee Brand B is sold for $5.69 for 12 ounces Question 1 options: A Coffee Brand A is a better buy because its unit rate is $2.29 per ounce B Coffee Brand A is a better buy because its unit rate is $0.44 per ounce C Coffee Brand B is a better buy because its unit rate is $2.11 per ounce D Coffee Brand B is a better buy because its unit rate is $0.47 per ounce.
Answer: Choice B
Coffee Brand A is a better buy because its unit rate is $0.44 per ounce
=======================================================
Explanation:
Brand A is sold for $6.99 per pound, which is the same as saying $6.99 per 16 ounces. The unit rate is 6.99/16 = 0.436875 = 0.44 dollars per ounce
Brand B is sold for $5.69 for 12 ounces. The unit rate is 5.69/12 = 0.47416 = 0.47 dollars per ounce
Brand A is cheaper per ounce compared to brand B.
------------------
Here's another way we can look at it
Brand A is $6.99 per 16 ounces. We can set up the equation below
6.99 dollars = 16 ounces
then divide both sides by 16 to turn "16 ounces" into "1 ounce"
So,
6.99 dollars = 16 ounces
6.99/16 dollars = 16/16 ounces
0.436875 dollars = 1 ounce
0.44 dollars = 1 ounce
is the unit rate for brand A.
Similar steps would happen with brand B as well.
how can you reflect a point over the y axis without graphing it?
Answer: You switch the point in the x-axis to the negative/positive of the number.
Step-by-step explanation:
So for example if you have the point (3,7), you would switch the 3 to -3 and you would keep the y the same.

20 points Without solving the systems, determine if there is 0, 1 or infinite solutions. Explain how you know.
Answer:
Infinite Solutions.
Step-by-step explanation:
3x+2y=8 for x:
3x+2y=8
3x+2y+−2y=8+−2y(Add -2y to both sides)
3x=−2y+8 3x 3 = −2y+8 3 (Divide both sides by 3)
x= −2 3 y+ 8 3
Substitute −2/3y + 8/3 for x in 4.5x+3y=12:
4.5x+3y=12
4.5( −2/3y+ 8/3 )+3y=12
12=12(Simplify both sides of the equation)
12+−12=12+−12(Add -12 to both sides)

The area of the square base is S(x), where x is the length of the concrete foundation, and the area of the base of the cylindrical tank is C ( r ), r is the radius of the cylindrical tank. What does the expression S ( C ( r ) ) represent?
Answer:
C(r) is the area of the base of a cylindrical tank with radius r.
We know that this area is:
C(r) = pi*r^2
S(x) is the area of the square base where x is the side length of the base.
S(x) = x*x
Now, we have the expression:
S( C(r)) wich means that we are evaluating the function S(x) in the point x = C(r)
Now, we have a problem here.
In S(x), S(x) is in units of area, and x is in units of length.
And the same for C(r), C(r) is in units of area, and r in units of length.
then we can not have x = C(r)
Then this expression does not represent anything, because the units do not match, so it has no physical sense.
