5 because if you plug in to get the equation 3x+20=7x then subtract 3x from both sides and divide by 4 from both sides
Multiply the numbers all together
Step-by-step explanation:
Total number of students= y
(25/100) xy= 200
25 xy = 200 x 100
25y 20000
y = 20000/25
y 800
total number of students = 800
Answer:
3/10, 0.3, and three tenths
Step-by-step explanation:
First, we are going to write the number of sports balls that are kickballs as a fraction. To do this, we are going to divide the number of kickballs by the total number of sports balls in the closet, giving us: 3/10.
Next, we want this same expression as a decimal. To convert from a fraction to a decimal, we are simply going to divide the numerator by the denominator. When we divide 3/10, we get 0.3, which is the answer to the second part of the question.
Finally, we want this answer in word form. To write the decimal in word form, we just state the number followed by the place that it's in. In this case, we have a three in the tenths place, which gives us three tenths.
Hope this helps!
This is a reflection along the y-axis. There is no work needed.
