9(30 + 7)

When you distribute (multiply) 9 inside the parentheses, it would look like:

(9 * 30) + (9 * 7)

When making a batch of orange juice for her basketball team Jackie used 5 times as much water as concentrate. There were 32 more

AnnZ [28]

Answer:

48 cups of orange juice, 24 containers.

Step-by-step explanation:

Given:

Jackie used 5 times as much water as concentrate to make orange juice.

There were 32 more cups of water than concentrate.

Question asked:

How much juice did she make in all ?

She poured the juice in 2 quart containers how many containers could she fill ?

Solution:

Let concentrate used in the juice = $x$

As Jackie used 5 times as much water as concentrate:

Then water used in the juice = $5x$

According to question:

To make orange juice 32 more cups of water used than concentrate is equals to to make orange juice, Jackie used 5 times as much water as concentrate, we will write this as:-

$x+5x=x+x+32\\6x=2x+32\\$

Subtracting both sides by $2x$

$4x=32\\$

Dividing both sides by 4

$x=8$

Concentrate used in the juice = $x$ = 8 cups

Water used in the juice = $5x$ = $5\times8=40\ cups$

Total quantity of juice =8 + 40 = 48 cups

Thus, she made 48 cups of orange juice for her basketball team.

Now, as she poured the juice in 2 quart containers, we have to find number of containers could be filled, we will simply divide total quantity of juice by 2 quart

Number of 2 quart containers = 48 cups $\div$ 2 = 24 containers

Thus, she can fill 24 containers.

Changing the y-coordinates will make all coordinates negative and give us an image, or reflection, in the third quadrantSwitching the coordinates will flip the figure back to the right orientationEach coordinate (x,y) is changed to (-y,-x)This is our general formula for rotating the figure 270 degrees about the origin .Changing the y-coordinates will give us an image in the third quadrantIn other words, it will be a reflection of the figure in the second quadrant Switching the coordinates will flip the figure back to the right orientation Each coordinate (x,y) is changed to (-y,-x)This is our general formula for rotating the figure 270 degrees about the origin
