A pencil and a ruler cost $1.50 together. The ruler costs $1.00 more than the pencil. How much does the pencil cost?
Answers
One way to deduce this is to divide 1.50 by 2 (equaling 0.75) and then subtracting .5 to get 0.25 because if it's $1 more, then the ruler would cost 0.75 + 0.5 and the pencil would cost 0.75 - 0.5, making a total of $1.50.
Another way is to make it an equation. Let's say the ruler is r dollars and the pencil is p dollars.
r + p = 1.50
r = p + 1.00
If we know these two equations, then you can substitute p + 1.00 in the 1st equation (instead of r). This gets us:
p + 1.00 + p = 1.50
You can simplify this into:
2p + 1.00 = 1.50
Then you subtract 1.00 from both sides:
2p = 0.50
And you divide 2 from both sides:
p = 0.25
Getting you the answer of:
The pencil costs $0.25

Answers:
The pencil costs $0.25
The ruler costs $1.25
Explanation:
Assume that the cost of the pencil is x and that the cost of the ruler is y.
We are given that:
1- The total cost is $1.5
This means that:
x + y = 1.5 ...........> equation I
2- The ruler costs $1 more than the pencil
This means that:
y = x + 1 ............> equation II
Substitute with equation II in equation I and solve for x as follows:
x + y = 1.5
x + x + 1 = 1.5
2x = 1.5 - 1
2x = 0.5
This means that:
cost of pencil = x = $0.25
cost of ruler = 1 + 0.25 = $1.25
Hope this helps :)

Answers
Answer:the answer is y=8500-150m
Step-by-step explanation:I say this because 150 is the amount of feet that it drops per minute m stands for minute so you would be multiplying 150 by whatever m would be.
Final answer:
The equation representing the airplane's elevation after m minutes is y = 8500 - 150m, where 8500 is the original elevation and 150m is the cumulative loss of elevation.
Explanation:
The question is trying to establish an equation that represents the elevation of the airplane in relation to time. Given the airplane starts at an elevation of 8500 feet and is losing height at the rate of 150 feet per minute, to find the elevation y after m minutes, we need to subtract the total feet lost from the original elevation. Therefore, the equation that represents this situation is: y = 8500 - 150m.
In this equation, 8500 is the original elevation and 150m represents the cumulative loss of elevation for each minute (encompassing m minutes).
