Step-by-step explanation:
How old are you?
Answer:
The original cable was 5.15 m long.
51: $13.70
53: $16.50
54: $17.85
55: 4.4 miles
56: $49.35
Step-by-step explanation:
The answer to the first question (the one about the cables): So you would solve it by adding the lengths of the cable together.
Cut off piece: 1.65 m Remaining cable: 3.5 m
To find the original length, we need to add the cut off piece and the remaining cable together.
1.65+3.5= 5.15
The original cable was 5.15 m long.

y values: 3,4,5,6
x values: 5,10,15,20
Step-by-step explanation:
I used a graphing calculator but y is increasing by one and x increases by 5 each time
Answer:
See below.
Step-by-step explanation:
A's number is x. B's number is y.
x = 5y - 10
First row: What is x when y= 3?
x = 5y - 10 = 5*3 - 10 = 15 - 10 = 5; x = 5
Second row: What is x when y = 4?
x = 5y - 10 = 5*4 - 10 = 20 - 10 = 10; x = 10
Third row: What is y when x = 15?
x = 5y - 10
Add 10 both sides x + 10 = 5y - 10 +10
x + 10 = 5y
But we're told x = 15, so 15 + 10 = 5y
25 = 5y
Divide both sides by 5 25/5 = 5y/5
5 = y y = 5
Fourth row: What is x when y = 6?
x = 5y - 10 = 5*6 - 10 = 30 - 10 = 20; x = 20

Two students are reading a novel. Ashley reads 10 pages per day. Carly reads 8 pages per day, but she starts
early and is already on page 40.
d=days
p=pages
Ashley: p=10d
Carly: p=8d+40
On day ____, both girls should be on page ____.
Answer:
On day 20, they should both be on page 200
Step-by-step explanation:
I set the 2 equations up:
10d=8d+40 and then subtracted 8d from both sides
2d=40 and then divided both sides by 2
d=20
I then took 20 and multiplied it by 10 for Ashley (200) and then multiplied it by 8 for Carly (160) and added 40 (200)
Hope this helps!
If x:y = 2:5, find the value of (-x+3y):(2x+y)
Answer:
let x=2t and y=5t
-x+3y = -2t+15t = 13t
2x+y = 4t+5t = 9t
So the ratio is 13t : 9t
So, the ratio is 13 : 9
What is the solution to this equation?
2x + x - 11 + 3 - 7x = 15
O -
A. x=-1
O B. - 13
O cx
O D. - 23
C. x=23
Answer:
Step-by-step explanation:
2x + x - 11 + 3 - 7x = 15
-4x = 23
x = -23/4

During tug of war, team A pulls to the East with 24N of force and team B pulls to the West with 32N of force. Which team will win and what is the net force?
Team B, 8N
Team B, 56N
Team A, 56N
Team A, 8N
Answer: Team B, 8N
Step-by-step explanation: I think it's team be because when doing the problem team a is 24 n to the right while Team B is 32 n to the left, and since they are pointing different directions you would subtract those and then get your answer. Since Team B has the larger force it will be the one to win.

What is the value of x in simplest radical form?
Answer:
25, I believe
Step-by-step explanation:
Given a=7 and b=24,
c = 25
Answer:
25
Step-by-step explanation:
a² + b² = c², by Pythagoras
In this case 'x' is the 'c' for hypotenuse length
7² + 24² = x²
49 + 576 = x²
625 = x²
√625 = x
25 = x
