The relationship between the number of cups of water, w, and the number of cups of

lemon juice, j, used in a recipe is described by the equation shown.

j = 2w

To evaluate the number of cups pr cup of juice, find the value of w given j=1

1=2w

w=1/2

iHalf a cup of water is needed for each cup of lemeonce ju

Solve the equation x+10=30

Answers

get x alone on one side and solve

x = 30 - 10
x = 20
X+10=30
Subtract 10 from both sides
X+10=30
-10 -10
X=20
Answer:
X=20

Solve for 2 unknowns
3y + 3x =24
6y+3x = 39

Answers

The two unknown variable in the two given equations are "x" and "y". 
3y + 3x = 24
Dividing both sides by 3 we get
y + x = 8 
x = 8 - y
Putting the value of y in the second equation we get
6y + 3x = 39
Dividing both sides by 3 we get
2y + x = 13
2y + 8 - y = 13
y = 13 - 8
  = 5
Putting the value of y in the first equation we get
y + x = 8
5 + x = 8
x = 8 - 5
x = 3
So the value of x is 3 and the value of y is 5. I hope the procedure is clear enough for you to understand.

Hugh has to earn at least $400 to meet his fundraising goal. He has only 100 books that he plans to sell at $8 each. Which inequality shows the number of books, x, Hugh can sell to meet his goal?

Answers

If you would like to find the inequality that shows the number of books Hugh can sell to meet his goal, you can do this using the following steps:

x = ? ... the number of books
$8 * x >= $400
8 * x >= 400
x >= 400 / 8
x >= 50 books

The correct result would be: $8 * x >= $400. 

Answer:

50 ≤ x ≤ 100

Step-by-step explanation:

Evaluate: xy - x (x - y^0) if x = 2 and y = -1/2

Hi

2(-1/2) - 2(2+(-1/2)^0)
= -2/2 - 2(2+(-1/2)^0)
 = -1 - 2(2+(-1/2)^0)
= -1 -2 (2+1)
= -1 -2(3)
= -1 -6
= -7

I hope that's help :)

If you have any further questions please let me know :)

2(- (1)/(2) ) - 2(2+(- (1)/(2))^0)

- (2)/(2) - 2(2+(- (1)/(2) )^0)

-1 - 2(2+(- (1)/(2) )^0)

-1 -2 (2+1)

-1 -2*(3)-1 -2(3)

-1 -6

-7

A recipe calls for 2 1/3 cups of honey. A second recipe calls for 3 3/4 cups of honey.Which expression should Cindi use to estimate how many cups of honey she needs in order to make sure she has enough for both recipes?

A.
2 1/2 + 4

B. 2 1/2 + 3


C. 2 + 4


D. 2 + 3 1/2

Answers

2 1/3 rounds to 2 1/2, and 3/4 rounds to 4.

Therefore we have:

2 1/2 + 4
2 (1)/(3) =2 (1)/(2) \n \n 3 (3)/(4)=4 \n \n 2 (1)/(2) +4 \n \n A

Subtract 14 inches from 4 feet, 2 inches.10 inches
3 feet
34 inches
5 feet

Answers

If you would like to subtract 14 inches from 4 feet 2 inches, you can calculate this using the following steps:

1 foot = 12 inches 
4 feet 2 inches = 50 inches
4 feet 2 inches - 14 inches = 50 - 14 = 36 inches
36 inches = 3 feet 

The correct result would be 3 feet.

3 ft. because 4 ft. converted to inches is 48 in. + 2 in. - 14 in. = 3 ft.
