Set this up as a ratio with inches on top and feet on bottom:
. Cross multiply to get 5x = 100. x = 25 inches
Greetings!Find the
Solution/Point of Intersection:
Rearrange the System:
Multiply the
First Equation by 2 and the Second Equation by 3:
Eliminate the x variable:
Divide both sides by 11:
Input this value into the First Equation:
Simplify:
Divide both sides by 3:
The Solution/Point of Intersection is:
I hope this helped!

Answer:
The answer is a point
Step-by-step explanation:
That happens because the points you have are in opposite corners, which means that they are the limits of the rectangle. so any point inside the rectangle is between that segment
Answer:
11. True
12. True
13. False
14. False
15. True
16. False
17. x = 2.5
Step-by-step explanation:
With problems 11 to 16, You have to replace the h in the equations with 3 and see if the equation is true or not.
11. You can simplify the equation by solving the number in the parentheses first. So the problem would be 3(3 - 4) since you replace the h with a 3. (3 - 4) equals -1. So now the problem simplified is 3(-1) which is 3 x -1 which equals -3. Meaning that 3(h - 4) = -3 is true since h is 3.
With 17 and 18, you have to replace what number you think is x. A easy way of doing this is working in reverse.
17. So 4x has to equal 8 when 2 is taken away. To find this out, we add 2 to 8 which would equal 10. Then we divide 4 from 10 which equals 2.5. In order make sure that this is correct, we will put the equation back into normal formula. So 4x - 2 = 8 becomes (4 x 2.5) - 2 = 8. (4 x 2.5) equals 10, so 10 - 2 = 8.
You can use them to help understand quantities such as
x, y
1, 2
2, 4
3, 6
this helps to show relation such as adding by two or you can have a multiplying rate of change whi chub can show that each time a number is multiplied by something it changes
like if the question states: Bob puts $500 into the bank and he collects interest of $10 once a week how much money does he make in interest in 4 weeks.
x, y
0, 500
1, 550
2, 600
4, 650
I think that maybe what you are looking for.
