Answer:
1. 5/3 is not equal to 3/5.
2. 7-(4+3) is equal to (4+3)-7
3. (x + y) + 1 is equal to x + (y + 1)
Step-by-step explanation:
1. 5/3 and 3/5 are completely different fractions and when you switch the denominator and the numerator you get a different fraction: 5/3 = 1 2/3, 3/5
2. If you solve both of them, they are equal because 7-7 = 7-7
3. This is equal due to the associative addition property, which means that when the addition of three or more numbers, the total/sum will be the same, even when the grouping of addends are changed.

The total weight W of such a plane is equal to
W = w + gf
where
w = weight of plane without fuel
g = number of gallons of fuel
f = weight of 1 gallon of fuel.
When carrying g = 10 gallons, the total weight is W = 1955, so
1955 = w + 10f
When carrying g = 42 gallons, the weight is W = 2131, so
2131 = w + 42f
We want to find W when g = 52, and to do this we first need to find the weight of the plane w and the weight of 1 gallon of fuel f.
Solve the system of equations,
w + 10f = 1955
w + 42f = 2131
We can combine the equations like so to eliminate w and solve for f :
(w + 42f) - (w + 10f) = 2131 - 1955
32f = 176
f = 11/2 = 5.5
Then solving for w, we get
w + 10 (5.5) = 1955
w + 55 = 1955
w = 1900
So, when the plane carries g = 52 gallons of fuel, the total weight is
W = 1900 + 52 (5.5) = 2186
Put the following equation of a line into slope-intercept form, simplifying all fractions. 3x+6y=-42
Answers
Answer:
y = -1/2x + 7
Step-by-step explanation:
3x + 6y = 42. Put everything except the y term on the right hand side, so subtract 3x from both sides.
6y = -3x + 42. You want 1y by itself, so divide everything by 6.
y = -1/2x + 7

(A 12 + (-10)
(B 12 - 10
(C -10 + 12
(D -10 - 12
Answers
Answer: D -10 - 12
Step-by-step explanation:
Temperature change is (Final T) - (Initial T)
(Final T) = -10C
(Initial T) = 12
(Final T) - (Initial T) = -10C - 12C
Temp Change - 22C

a point moves so that it's y-coordinate is always 2 less than it's x-coordinate.
1) write an equation for it's path
2)where does it cross the x-axis
3) where does it cross the y-axis
4) what is it's slope
Answers
Step-by-step explanation:
y is always 2 less than x
1) y = x- 2
2) where does it cross the x-axis ? that means y = 0.
0 = x - 2
x = 2
3) where does it cross the y-axis ? that means x = 0
y = 0 - 2 = -2
4) the slope is always the factor of x.
in
y = x - 2.
the factor of x is simply +1.
If its y-coordinate is always 2 less than its x-coordinate, this is expressed as y = x - 2
Slope and equationsFrom the given information
Let the y-coordinate be yLet the x-coordinate be xIf its y-coordinate is always 2 less than its x-coordinate, this is expressed as:
y = x - 2
The equation of the path is y - x - 2
2) The point where th line cuts the x-axis is at y = 0
0 = x - 2
x = 2
The point is at (2, 0)
3) The point where th line cuts the y-axis is at x = 0
y = 0 - 2
y = -2
The point is at (0, -2)
4) The standard equation of a line is y = mx + b where m is the slope. Given the equation y = x - 2
Comparing:
mx = 1x
m = 1
Hence the slope of the equation is 1

14 year it would take to earn $1000 simple interest on an investment of $800 at 9% annual interest.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Let the number of years be represented as T
Now , the equation will be
The simple interest I = $ 1000
The rate of interest R = 9 %
The principal amount P = $ 800
Simple Interest = ( Principal Amount x Rate x Time Period ) / 100
Substituting the values in the equation , we get
1000 = ( 800 x 9 x T ) / 100
On simplifying the equation , we get
72T = 1000
Divide by 72 on both sides of the equation , we get
T = 13.89 years
Therefore , the number of years is approximated to 14 years

1 ton is equal to 2,000 pounds. How many pounds are in 5 tons, 230 pounds?
Answers
Answer: 10230
Step-by-step explanation:
The amount in pound is 1230 pounds.
What is Unitary Method ?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
1 ton is equal to 2,000 pounds.
So, 5 tons and 230 pounds
= 5 x 2000 + 230
= 1000 + 230
= 1230 pounds.
