Answer:
6.75 minutes / mile.
Step-by-step explanation:
Time: 13.5 minutes
distance: 2 miles
rate: ?
You want the units to be minutes / mile. That's not the usual units for a rate. You have to be careful how you set this up.
13.5 minutes
2 miles
13.5 /2 = 6.75 minutes / mile = 6 minutes 45 seconds / mile

Which is better to buy? 3-yard roll of wrapping paper for $7.02. 8-foot roll of wrapping paper for $7.36
Answer:
3 yard roll of wrapping paper for $7.02 is better to buy.
Step-by-step explanation:
1 yard = 3 foot
3 yard = 9 foot
$7.02 / 9 foot = $0.78/foot
$7.36 / 8 foot = $0.92/foot
0.78 < 0.92
Therefore, 3 yard roll of wrapping paper for $7.02 is better to buy.

x: 0
f(x): 0.5
x: 3
f(x): -1
Step-by-step explanation:
Answer:
3/2, 1/2, - 1
Step-by-step explanation:
x + 2y = 1 --> this is 'f(x)'. Sub in the each x-value to the equations.
First part:
x = -2
x + 2y = 1
-2 + 2y = 1
2y = 3
y = 3/2
Second part:
x = 0
x + 2y = 1
0 + 2y = 1
2y = 1
y = 1/2
Third part:
x = 3
x + 2y = 1
3 + 2y = 1
2y = -2
y = -2/2
y = - 1
The mean length of 7 planks of wood is 1.35m. When an extra plank of wood is added, the mean length of a plank of wood increase to 1.4m. the length of the extra plank of wood that was added is Select one a. 2. 4 b. 1 C. 1.25 d. 1.75V
Answer: Hello There!................
Mean = Sum of observation / total number of observation
Mean = 1.35m
1.35 = Sum of length of 7 wood planks/ 7
1.35*7 = Sum of the length of 7 wood planks
9.45 = Sum of the length of 7 wood planks
Let the length of extra added wood plank = x
So,
(Sum of the length of 7 wood planks + x) / 8 = 1.4m
(9.45 + x) / 8 = 1.4
9.45 + x = 1.4 * 8
9.45 + x = 11.2
x = 11.2- 9.45
= 1.75
So,
The length of extra added wood plank = 1.75m

The sum of 4 times a number and - 7, added to 9 times the number
Answer:
13x – 7
Step-by-step explanation:
If "a number represents x", then:
The sum of 4 times a number and - 7, added to 9 times the number = (4x + -7) + 9x.
(4x + -7) + 9x →
(4x + 9x) + -7 →
(13x) + -7 →
(13x) – 7 →
13x – 7.
The unknown number will be equal to 4.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the sum of 4 times a number and - 7, added to 9 times the number is 45. The value of the unknown number will be calculated as below:-
The sum of 4 times a number and - 7, added to 9 times the number = (4x + -7) + 9x.
(4x + -7) + 9x = 45
(4x + 9x) + -7 = 45
(13x) + -7 = 45
(13x) – 7 = 45
13x – 7 = 45
13x = 45 + 7
13x = 52
x = 4
Therefore, the unknown number will be equal to 4.
The complete question is given below:-
The sum of 4 times a number and - 7, added to 9 times the number is 45. Calculate the value of an unknown number.

E is the midpoint of DF, DE = 3x + 4 and EF = 5x - 2. Find DE, EF, and DF.
Since E is the midpoint of DF, DE and EF are two halves of DF. First, let's write down what we know.
DE = 3x + 4
EF = 5x - 2
DE = EF
DE + EF = DF
Now, let's plug our values for DE and EF into our first expression.
3x + 4 = 5x -2
Add 2 to both sides and subtract 3x from both sides.
6 = 2x
Divide both sides by 2
3 = x
Let's plug 3 in for x into DE.
DE = 3x + 4 = 3(3) + 4 = 9 + 4 = 13
DE = EF = 13
We can plug 13 in for DE and EF to get DF
DF = DE + EF = 13 + 13 = 26

Answer:
50% of 320 is equal to 80% of 200.
Step-by-step explanation:
Given,
50% of 320 is equal to 80% of a number (let it be x)
Now,
50% of 320
= 50% × 320
= 50/100 × 320
= 50/10 × 32
= 5 × 32
= 160
Also now,
160 is equal to 80% of x.
80% of x = 160
80% × x = 160
80/100 × x = 160
8/10 × x = 160
4/5 × x = 160
4/5x = 160
x = 160 ÷ 4/5
x = 160 × 5/4
x = 40 × 5
x = 200
