**Answer:**

35 square inches

**Step-by-step explanation:**

S = ( 1/3 x 15 ) x ( 1/3 x 21 ) = 5x7= 35 square inches.

Hope this helps you.

The answer is b. Great job! here ill show you the work.

15x +90 > 270

move constant to the right side and change its sign, like this:

15x>270-90

then subtract the numbers

15x>180

lastly, divide both sides by 15.

hope this helped!

**Answer:63**

**Step-by-step explanation:**

**Joy will need to use 9 cups of strawberries for 6 cups of blueberries.**

**Step-by-step explanation:**

Given,

Cups of blueberries used for 3 cups of strawberry = 2

Ratio of cups of blueberry to strawberry = 2:3

Joy wants to use 6 cups of blueberries.

Let,

x be the cups of strawberry for 6 cups of blueberries.

Ratio of cups of blueberries to strawberries = 6:x

Using proportion;

Ratio of cups of blueberry to strawberry :: Ratio of cups of blueberries to strawberries

Product of extreme = Product of mean

Dividing both sides by 2

**Joy will need to use 9 cups of strawberries for 6 cups of blueberries.**

**Answer:**

a. The slope is 5/4

b. The equation in slope and intercept form is y = 5/4·x + 12

c. The base cost of making a fruit juice is $12

**Step-by-step explanation:**

The equation that gives the cost in dollars of making your own fruit juice is given as follows;

y - 2 = 5/4·(x + 8)

a. The slope = The coefficient of x = 5/4

The slope = 5/4

b. The equation can be presented in slope and intercept form, y = m·x + c, as follows;

y - 2 = 5/4·(x + 8)

y = 5/4·x + 10 + 2

y = 5/4·x + 12

c. The base cost of making a fruit juice = The cost added to any quantity of fruit, x made = The y-intercept, c = 12

The base cost of making a fruit juice = $12.
