Question

In April, the water level in a mountain reservoir increased 0.6 m as the snow began to melt. In May, the water level increased another 0.3 m. In June, the water level remained constant; but in July the water level decreased by 0.2 m due to a dry spell. At the end of July, the water level was 14.2 m. What was the water level at the beginning of April?

How would I solve for this?

14.2 = 0.6+0.3-0.2+x

I think this is it but I am not to sure.

Answer 1

The correct equation is 14.2 = 0.6 + 0.3 - 0.2 + x, where x is the water level at the beginning of April. After calculating the net change of 0.7 m, we find that x = 14.2 m - 0.7 m, which means the water level at the beginning of April was 13.5 meters.

Step-by-step explanation:

To solve for the water level at the beginning of April, we can set up an equation based on the changes during the subsequent months. The equation is correct as you've written it: 14.2 = 0.6 + 0.3 - 0.2 + x, where x is the water level at the beginning of April. Now, let's rearrange the equation to solve for x:

14.2 = x + 0.7

We combine the changes to the water level by adding the increases and subtracting the decreases from the final water level. The 0.6 m and 0.3 m are increases, while the 0.2 m is a decrease, resulting in a net increase of 0.7 m (0.6 + 0.3 - 0.2).

To find the water level at the beginning of April (x), we simply subtract 0.7 m from the final water level:

x = 14.2 m - 0.7 m

x = 13.5 m

Therefore, the water level at the beginning of April was 13.5 meters.

Answer 2

Step-by-step explanation:

Base on the given condition, formulate:

0.6+0.3-0.2

0.9-0.2 equals 0.7percent.and turn it into a percentage,which will give you 70 percent
