Answer:
50% = 50/100 = 0.5
20% = 20/100 = 0.2
25% = 25/100 = 0.25
10% = 10/100 = 0.1
Now let's begin our calculation
50% of 64=(0.5*64)=32
20% of 55=(0.2*55)=11
25% of 16 = (0.25*16) =4
10% of 200=(0.1*200)=20
20% of 86=(0.2*86)=17.2

Step-by-step explanation:
Answer:
one solution
Step-by-step explanation:
3(x-2) =22 -x
Distribute
3x - 6 = 22-x
Add x to each side
3x+x-6 = 22-x+x
4x+6 = 22
Subtract 6 from each side
4x+6-6 = 22-6
4x= 16
Divide by 4
4x/4 = 16/4
x=4
There is one solution
Answer:
If the mean of four numbers is 7, we know that their sum is 7 * 4 = 28. We can use this information to find the last number. If the fourth number is x, we can write:
2 + 5 + 17 + x = 28
24 + x = 28
x = 4
