Step-by-step explanation:
- 3x = 2x + 2
3x - 2x = 2
x = 2
2. 3x + 5 = 4x + 1
4x - 3x = 5 - 1
x = 4
3. 6x + 3 = 3x + 12
6x - 3x = 12 - 3
3x = 9
x = 3
Answer:
A Method For Simple Cases
Step 1: Find two numbers that multiply to give ac (in other words a times c), and add to give b.
Step 2: Rewrite the middle with those numbers:
Step 3: Factor the first two and last two terms separately:
Step-by-step explanation:
For the first question which is y=x/3, here as we see that both are in top. So they represents direct variation and constant of variation is 1/3 .
For the second question , which is 6/y=x, y is denominator and x is in the denominator. So they represents inverse variation and the constant of proportionality is 6 here .
You might think that the volume of a circle is needed to solve this problem but you can do it in a more simplified manner. First figure out how much water 85 marbles displace.
26-20.9=5.1 liters of water
Now, let us see how much water 200 marbles displace.
85 marble x (200/85) = 5.1 liters x (200/85)
200 marbles = 12 liters
We can find the amount of water needed to fill the tank now.
26-12=14 liters of water
answer: 14 liters of water
Answer:
should be 82%
