Arrange ratio:
<span>
If the dog ate 12 muffins and this accounted for three-tenths of total how many muffins is a whole? Therefore, our ratio is as follows:
where 1 is a whole, and 3/10 = 0.3
12 ----------- 0.3
x ------------- 1
Multiply on the cross:
12 * 1 = 0.3 * x
0.3x = 12 |:0,3
x = 40
There are 40 muffins.</span>
7. Easiest method is substitution. Since y=x/2, then:
2x+3(x/2)=28
8.Substituting again, we get:
3x-6x=6
-3x=6
x=-2
(-2,6)

Answer:
80 points
Step-by-step explanation:
There is a total of 400 possible points so you are going to want to find 20% of that 400 points. To find that 20% you have to multiply 20×400=8000 THEN you want to divide that by 100 ( because that is the total possible percent and you get 80.
53 has no factors besides 1 and 53 because it is a prime number so there is no prime factorization that can be done
