Jacob mixes ⅓ cup of yellow paint for every ⅕ cup of blue paint to make green paint. How many cups of yellow paint are needed fo
Nana76 [90]

Answer:

\frac{5}{3} cups

Step-by-step explanation:

Jacob mixes \frac{1}{3} cup of yellow paint for every \frac{1}{5} cup of blue paint to make green paint.

The ratio of yellow paint to blue paint =  \frac{1}{3} : \frac{1}{5}

                                                              = 5:3

 \frac{1}{5} cup of blue paint =  \frac{1}{3} cup of yellow paint

 1 cup of blue paint =  \frac{1}{3} ÷ \frac{1}{5} cup of yellow paint

⇒ \frac{1}{3} ÷ \frac{1}{5}

⇒ \frac{5}{3}

Hence, For 1 cup of blue paint needed \frac{5}{3} cups of yellow paint.

Which algebraic expression is represented by the model?
DerKrebs [107]

Answer:

3(2x+2) = 6x + 6

Step-by-step explanation:

Those are algebra tiles, so it is saying (if you read across the top) 2x +2 then if you read down you have 3 units, so the dot means 2x + 2 multiplied by 3

If you write it in algebraic terms it is 3(2x+2) so the answer when you distribute is 3 (2x) + 3(2) so 6x + 6, and if you count the number of red rectangles you have 6 of them, hence the 6x, and if you cound the units in gray you have 6 of them, hence the 6.

Algebra tiles are used to demonstrate algebra concepts
