Deirdre joelle are reading the same book Deirdre Read three times as many pages of the book as Jowell together the read 48 pages which equation can be solved to. Find the number of pages Joelle reads
Answers
Answer:
3x + x = 48
12 pages
Step-by-step explanation:
let the number of pages read by Joelle be represented by x
Joelle = x pages
Deirdre = 3x (since she reads 3 times as much pages as Joelle)
3x + x = 48
4x = 48
x = 12 pages
So Joelle reads 12 pages
Solve for x: 14x = 196.

Answer:
14
Step-by-step explanation:
Answer:
the answer is X = 14
Step-by-step explanation:
So you need to single out the X
You do this by doing the opposite of X,
right now X is being multiplied by 14
The opposite of Multiplaction is division
That means you divide X by 14
But dont forget, what you do one side you do to the other.
This means you also Divide 196 by 14
196 ÷ 14 = 14
meaning X = 14

Answer:
B
Step-by-step explanation:
Using the method of cross- multiplication
A
7x = 252 ( divide both sides by 7 )
x = 36 ≠ 4
B
21x = 84 ( divide both sides by 21 )
x = 4
C
5x = 2 ( divide both sides by 5 )
x = 0.4 ≠ 4
D
5x = 200 ( divide both sides by 5 )
x = 80 ≠ 4
The proportion where x = 4 is B

The question is incomplete. Here is the complete question.
Mr. Jackson decides to build a planter in the shape of a cube fo rhis wife. The top of the planter will be open so his wife can plant and water her flowers. The perimeter of the bottom of the planter is 12 feet.
How many square feet of material does Mr Jackson need to build the planter?
(a) 27 square feet
(b) 45 square feet
(c) 60 square feet
(d) 720 square feet
Answer: 45 square feet
Step-by-step explanation: A cube is a regular solid with six square faces.
Square is a quadrilateral with 4 right angles and 4 equal sides. So a cube is solid formed by 6 squares.
Perimeter is the sum of all the sides. For a square, perimeter is given by
P = 4s
Then, side of the bottom is
[tex]s=\frac{P}{4}[/tex]
[tex]s=\frac{12}{4}[/tex]
s = 3
Area of a square is
[tex]A=s^{2}[/tex]
[tex]A=3^{2}[/tex]
A = 9
The planter is a cube with 5 faces, because the top is open. Then, total area is
[tex]A_{t}=9+9+9+9+9[/tex]
[tex]A_{t}=[/tex] 45
Mr Jackson will need 45 square feet of material to build the planter.

Another submarine's descent can be represented as `y=-240x`, where u is the elevation and x is time in hours. How long will it take this submarine to make the descent (2,100 feet below the surface)?
Answers
Answer:
The time it will take is 8hours 45mins.
Step-by-step explanation:
Since y = –240x represents a submarine descent. We are looking for how long, that is the time, it will take for the submarine to make a descent of 2100. We know that y is the elevation, if it is descending it will be in the negative direction, making it -ve.
A descent of 2100 means y = –2100. Hence,
–2100 = –240x
x = –2100/–240 = 8.75hours = 8hours 45minutes. (0.75hours = 3/4hours = 3/4 x 60mins = 45mins).
