Answer:
<u><em>-71</em></u>
Step-by-step explanation:
Please excuse my dear aunt sally ( parentheses, exponents, multiplication, division, addition, and subtraction )
Flour : sugar = (1/3) : (1/5) = 5 : 3 . . . . . . . . multiply the first ratio by 15 to eliminate fractions
The total of ratio units in the last representation is 5+3=8, so for a recipe of 16 cups, each ratio unit will stand for 16/8 = 2 cups.
Multiplying the ratio by 2 cups, we find Amanda will need
... 10 cups flour : 6 cups sugar
for her recipe.
The first step to solving this equation is to change the signs on both sides of the equation
y = -
x + 3
Since we don't know what x is but we do know why y is,, we will write our answer with the answer to y and x being left as undefined.
y = -
x + 3, x ∈ R
Let me know if you have any further questions

I think what ur sopposed to do is multiply all the numbers+ find out what number the letters are then multiply that with the other numbers, if that makes sence
