Say you have the equation 5(5x+7)=155
First you multiply 5 by everything in the parenthesis so you get 25x+35=155 then subtract 35 from both sides and get 25x=120 then 120 divided by 25 equals 4.8 so x=4.8

kramer
Y + 2 = -2(x - 5)

Simplify.

y + 2 = -2x + 10

Subtract 2 from both sides.

y = -2x + 10 - 2

Simplify.

y = -2x + 8 → Slope-intercept form

Our answer is the second option : y=-2x+8

~Hope I helped!~

nata0808 [166]

Answer:

B

Step-by-step explanation:

Here, we want to the find the value of the x.

By bisecting the angle, the ray in question divides it into two other angles which are equal.

We proceed as follows;

x + 7 = 2x -11

Collect like

I need help please im only in the 7th grade &amp;’ i don’t know what to do !

Answer: In the chart, put 6 in place of the question mark.

The equation should be something like w = 2/3 p

W is the number of quarts of water. P is the number of quarts of Pineapple juice.

This week they will need 3 times the previous week so 18 quarts of pineapple juice and 12 quarts of sparkling water.

Step-by-step explanation:

If the basic recipe is 2 water to 3 juice, and they used 4 quarts if water, you can see that is <u>double the amount of</u> water so you need <u>double the amount  </u> of juice. 2 times 3 is 6.

<em>Unit rate</em> means for ONE quart of juice, how much sparkling water is used. that should be  1 Pineapple Juice for 2/3 Sparkling water

OR

for EACH quart of sparkling water, how much juice do you need.

that would be 1 unit of Sparkling Water for 1 1/2 units of Pineapple Juice
