Aschool cafeteria makes cheese sauce for macaroni using 15 cups of swiss cheese 17 cups of cheddar cheese. perry tries to make the sauce for a family party using 5 cups of swiss cheese and 7 cups of cheddar cheese. is perry using the correct ratio? explain. (pls do explain. it's on my school work and i need an explanation.)

(middle school ratios)

For this case we have that by definition, it is known as proportion to the relationship of equality that exists between two reasons, that is, between two comparisons. That is: if is a ratio, then the equality will be a proportion.

Then, 15 cups of Swiss cheese for every 17 cheddar:

1

We want to verify the proportion:

Equality is not met!

You are not using the correct proportion

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
