x+15=78
Answer to the first question: 7/10ths of a mile
Explaination: When adding fractions, you need to have a common denominator. Since dividing 3/10 by 2 to get a denominator of 5 makes 3 a decimal, it's easier to multiply 2/5 by 2 to get a denominator of 10. You do the same to the top that you do to the bottom: 
. From there, just add 4/10 and 3/10 to get the answer: 7/10ths of a mile.
Answer to the second question: Daniel read three (3/10) more books
Explaination: Since you can't evenly multiply 5 or 2 to get the opposite number, it's easier to multiply to the lowest common multiple. The easiest way to find that is to multiply both denominators (5*2=10). You'll have to multiply the numerator by the same amount you multipled the denominator by. For Daniel, that would mean: 
. For Edgar, that would mean: 
. So, Daniel read 3 more books than Edgar.
Answer to the third question: 2/4 mile (or 1/2 a mile)
Explaination: 2/8 can be simplified, by dividing the top and bottom by 2, resulting in 1/4. Since both fractions have the same denominator (/4), you can add them to get 2/4ths. This can be simplified further to half (1/2) a mile.
Because Philip is conducting a survey that pertains to the weight of the cows, he needs statistics that directly relate to weight.
The cows being overweight doesn't give Philip concrete information on the weight of the cows, as it doesn't give the amount of pounds a cow weighs. Average age has nothing to do with weight, and normal body weight doesn't give concrete information on weight.
The answer is "<span>What is the weight of each cow on the farm?".</span>
it’s a because you need all those figures to make it happen
Ah hah ! People on Brainly are always asking us where they can
use this stuff in real life. HERE is a perfect example of where
you can use Least Common Multiple in real life . . . when you're
buying hot dogs and buns !
When they come in packs, with different numbers in each pack
but you want to wind up with the same number of each item,
the number of each item that you should buy is the LCM of
the numbers in each pack.
Yadira's mom absolutely aced her math in Middle School, so she
knows right away that the LCM of 9 and 12 is 36 . This tells her
that she should buy 36 hot dogs (3 packs) and 36 buns (4 packs).
