5x-2 is a factor.
The complete factored expression is 3(5x-2)(y-3)

If y= -12 when x= 9<br> find y when x= -4

Andre45 [30]

This is a fraction. So it's y over x. So -12 over 9 equals y over -4. After you put those in fractions, you cross multiply. So -12(-4) is 48, and 9y. Then you set them equal to each other, so 48=9y. You divide 9 on both sides and your answer should be y=5.3

Amelie is making a recipe that uses 1 3/4 cups flour. She is making 2 1/2 times the original recipe.

Answer:

She would need $4\frac{3}{8}$ flour to make $2\frac{1}{2}$ times the recipe.

Step-by-step explanation:

To make 1 recipe Amelia uses = $1 \frac{3}{4}\ cups$ of flour.

So, to make $2\frac{1}{2}$ times the recipe she would need = $1 \frac{3}{4}\times 2\frac{1}{2}$ .

We evaluate the above mixed numbers by converting them to fraction(by multiplying denominator with whole number and adding to numerator and write as fraction of same denominator.).

$=\frac{7}{4}\times \frac{5}{2}$

$=\frac{35}{8}$

Then converting back to mixed number (by dividing the numerator by denominator and writing the quotient as the whole number and the remainder as fraction with same denominator.

$\frac{35}{8}=4\frac{3}{8}$
