Briana has 4 1/2 cups of oats. She uses 2 1/4 cups of oats to make oatmeal- raisins cookies, then borrow 1 cup of oats from her
insens350 [35]

Answer:

She has enough with \frac{3}{4} cups left over.

Step-by-step explanation:

For this equation, it's probably easiest to use improper fractions.

At the start, she has 4\frac{1}{2} cups, or \frac{9}{2}, which can be converted to \frac{18}{4} (which is useful for the next part) by multiplying the numerator and denominator by 2.

When she uses 2\frac{1}{4} cups, which can be converted to \frac{9}{4}. When subtracting this from the original, you get \frac{18}{4}-\frac{9}{4}=\frac{9}{4}.

She borrows another cup, or \frac{4}{4} of a cup, which gets added on to the previous result, giving \frac{9}{4}+ \frac{4}{4}=\frac{13}{4}.

The recipe calls for 2\frac{1}{2} cups, which can be converted to \frac{5}{2} or \frac{10}{4}.

\frac{13}{4}-\frac{10}{4}=\frac{3}{4}, meaning she has \frac{3}{4} cups left over.

** solving this mainly uses conversion to improper fractions and adding/subtracting fractions, which may be skills you would like to practice. I'm always happy to help!

Solve for X: 39 - 7x = -4 (7x + 7) = 4
gtnhenbr [62]

Subtract 39 from both sides

-7x = -4 - 39

Simplify -4 - 39 to -43

-7x = -43

Divide both sides by -7

x = -43/-7

Two negative make a positive

<u>x = 43/7</u>

<em>For the second equation;</em>

Simplify brackets

7x + 7 = 4

Subtract 7 from both sides

7x = 4 - 7

Simplify 4 - 7 to -3

7x = -3

Divide both sides by 7

<u>x = -3/7</u>
