45 points 35 is less than half a number equals 14. what is the number?

Let N be the number we seek. Let's translate the words into math.

35 less than                           -35

half a number                       1/2 N

equals    14                               = 14

Now we put it together with a plus sign between the first two parts. No sign is needed between the second and third, as an equals sign is there.

-35 + 1/2 N = 14

We clear fractions at this point and multiply the whole equation by 2. We choose 2 because it's the lowest common denominator of 1, 2, and 1.

-70 + N = 28

N = 98               < add 70 to both sides.

Thus the mystery number is 98.  

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
