Answer:
<u>The solution to the system of equations given is (3, 2)</u>
Step-by-step explanation:
Let's solve the system of equations given:
2y = 4
-x = -3
****************
2y = 4
y = 4/2
y = 2
____________________
-x = - 3
x = 3
<u>The solution to the system of equations given is (3, 2)</u>
Answer:
144
Step-by-step explanation:
The equation to find c is:
So put -24 into b:
Which simplifies to:
144
So if you want to test this:
x^2 - 24x + 144
is
(x-12)^2
This can be the equation, if you put it in x and you put it in y. So x plus y is equal to 30,000, 5/100x plus 11 over 100y is equal to 2200. The answer is y is equal to 70, 000 over 6. X = 11000/6
The answer is n=(a-b)-1 because when you subtract a-b, you get almost the number of pages, but as you are counting the page b which has is not torn out, you must subtract 1 to get the correct answer if you plugged in a variable
I'm assuming that you meant to write 'two 100-w per hour light bulbs used a total of 400w. how many hours did the bulbs run'
so each used 100w per hour and there are 2 light bulbs so in 1 hour 200w is used
200wh times x hour=200wx=400w
divide both sides by 200w
x=2
they ran for 2 hours
