Note the equal sign. What you do to one side, you do to the other. Isolate the a.

Add 4 to both sides

a- 4 (+4) = 15 (+4)

a = 15 + 4

a = 19

19 is your answer for a

hope this helps

The answer is 19.

-4 + a = 15

4 + -4 + a = 15 + 4 -Add 4 to both sides

a = 19

Evaluate the expression 50 - t when t equals 10, 20, or 25. Then

ludmilkaskok [199]

Answer:

$(t,50-t) = \{(10,40),(20,30),(25,25)\}$

Step-by-step explanation:

Given

$Expression: 50 - t$

Required

Evaluate when:

$t = \{10,20,25\}$

When $t =10.$

The expression is:

$50 - t = 50 - 10$

$50 - t = 40$

When t = 20

The expression is:

$50 - t = 50 - 20$

$50 - t =30$

When $t = 25$

The expression is:

$50 - t = 50 - 25$

$50 - t =25$

The result is:

$(t,50-t) = \{(10,40),(20,30),(25,25)\}$

At D.J.s Drink stand Erika ordered a cup of fruit punch made using 1/4 cup of lemonade 1/12 cup of cranberry juice. What fractio

Zepler [3.9K]

The fraction of the orange juice will be 2/3cup.

Why?

Since there is no additional information, let's assume that the fruit punch is made using just three juice fruits, lemonade juice, cranberry juice and the rest is orange juice.

We can calculate the fraction of the orange juice using the following information:

$FruitPunch=\frac{1}{4}Lemonade+\frac{1}{12}Cranberry+Orange\\\\1cup=\frac{1}{4}cup+\frac{1}{12}cup+Orange\\\\1cup-(\frac{1}{4}cup+\frac{1}{12}cup)=Orange\\\\1cup-(\frac{12+4}{4*12})=Orange\\\\Orange=1cup-\frac{16}{48}cup=1cup-\frac{1}{3}cup=\frac{3-1}{3}cup=\frac{2}{3}cup$

Hence, we have that the fraction of the orange juice will be 2/3cup.

Have a nice day!

P=3y/q solve for y make sure to add steps pls

Likurg_2 [28]

Answer:

Solving for y gives:

$y = \frac{pq}{3}$

Step-by-step explanation:

Linear equations are the equations that are degree one equations. When it is asked to solve an equation for a specific variable that means that the specified variable has to be isolated on one side of the equation i.e. in the given question solving for y means isolating y on one side of the equation.

Given equation is:

$p = \frac{3y}{q}$
