Alexia uses two and one-third cups of flour for each batch of cookies she makes. If she makes three-fourths of a batch of cookies, how much flour does she use?

She uses 1.7475 cups of flour.

Step-by-step explanation:

This question can be solved using a rule of three.

For each batch of cookies:

Two and one-third cups of flour.

So cups.

If she makes three-fourths of a batch of cookies, how much flour does she use?

3/4 = 0.75 batch of cookies. How much flour?

1 batch - 2.33 cups.

0.75 batches - x cups

x = 2.33*0.75

x = 1.7475

She uses 1.7475 cups of flour.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
