One number is three less than four times another. If their difference is 48, what is the larger number?
1 answer:
Answer:
65
Step-by-step explanation:
Let x be the number and y be the another one.
x=4y-3
x-y=48
Substitute x=4y-3 into x-y=48
(4y-3)-y=48
3y=51
y=17
[Since we know x is larger than y (4y-3), we need to use y to calculate out x.]
Substitute y=17 into x=4y-3
x=68-3
x=65

First, move 9x^2 to the right:
7y^2 = 42 - 9x^2
Then, divide 7 on both sides:
y^2 = 6 - 9/7 * x^2
The slope is 0 because there is no slope it is not pointing up nor is it down. It is just a straight line. I hope this helps!! Have a nice day!!
Add the three strips of cut wood together:
John will need to cut a total of 50.05cm of wood.
Subtract this total from the strip John has:
The leftover piece will be 21.95cm long.
This cannot be expressed as an answer but the expression for that is 3L-5
Ok I almost have the answer. Do you want me to explain how I did it?
