Answer:
1000
Step-by-step explanation:
if you were rounding it would be 1380, 1400, or 1000 because it isn't over 5
You have effectively wasted 1 hour of my time. Congratulations.
115 = 65 + 50
45(65) + 35(50) = 2925 + 1750 = 4675
45(50) + 35(65) = 2250 + 2275 = 4525
115 = 55 + 60
45(55) + 35(60) = 2475 + 2100 = 4575
Therefore 55 large boxes and 60 small boxes. Absolutely no more of these questions; I got stuck for 40 minutes using trial and error, even though that's the only way you can solve two variables in one equation with integers.
3,000
whenever a number is 500 or over, you round it to the next thousand
hope this helps! :)
Directly proportional, both increase/decrease, Multiple k(constant you needed to solve for)..
Inversely --one increases as the other decreases, increase the denominator & fraction gets smaller.... So
Problem:
Dirextly to X (× by X)
Inversely to Y, (÷ by Y)
Z= k X/Y
Solve, working backwards: Z =5 becomes
5 = k (X) ÷ (Y). And
X=15 and Y =9 becomes
5= k(15)/(9). Undo ÷9, ×9 both sides
45= k(15). Now undo ×15 by ÷15 both sides
45/15 = 3. So k=3, (also called your constant of variation)....and your Equation/Proportion becomes...
Z = 3X/Y
Use the new #s.... X=23, Y=14
Z= 3×23÷14 = 69/14. If they want spirochete answer divide and round to corresponding # if decimals
Answer:
<u>-6</u>
-7
Step-by-step explanation: (4,5) and (-3,-1)
- Y2 represents -1
- Y1 represents 5
- X2 represents -3
- X1 represents 4
<u>Y2 - Y1</u>
X2 - X1
<u>-1 - 5</u>
-3 - 4
<u>-6</u>
-7
Hope this helps you!!! :)
