Hello there!
ax + bx = 13
We want to start by factorizing out the variable x
x(a + b) = 13
Then divide both sides by a+b
x( a + b)/a + b = 13/a+b
x = 
2)
ax + 5 = cx
Should start by adding -cx on both sides
ax + 5 - cx = cx - cx
ax + 5 - cx = 0
ax - cx = 0 - 5
ax - cx = -5
Then again, we need to factor out x because there's two of them
x( a - c) = -5
Then divide both sides by a-c
x(a - c)/ a - c = -5/a - c
x = 
3)
ax + b = dx - 1
Start by adding -dx on both sides
ax + b - dx = dx - 1 - dx
ax - dx + b = -1
ax - dx = -1 - b
Here we go again, factor out x
x( a - d) = -b - 1
x =

Answer:
7.5 litres.
Step-by-step explanation:
Volume of water lost in 1 month = 2.5 * 10^-4 * 3 * 10^5
= 2.5 * 3 * 10^(-4+5)
= 7.5 * 10^1
= 7.5 litres (answer)
Answer & Step-by-step explanation:
number of Dave's coins = number of Zack's coins + 5
The question is asking to find the difference in prices paid (thus "<em>more</em>"), completely unrelated to the number of coins Zack bought as these two numbers are independent of one another. The difference in price can be found by simply multiplying the cost of one coin by 5.
