Hello!

Write the equation in mathematical form

\sqrt{3x+1} =4

Now solve it algebraically

Square both sides

3x + 1 = 16

Subtract 1 from both sides

3x = 15

Divide both sides by 3

x = 5

The answer is 5

Hope this helps!

Greeley [361]
Just look at the numerators! The numerators are the numbers above the line. See how for bread the top number is higher than the top number for flour? Because 2 is bigger than 1. That means Jan has used more bread!

The ratio of the the number of Sally's stickers to the number of Eric's stickers was 3:5. Sally then brought another six sticker
Ne4ueva [31]

Answer: Eric has 20 stickers

=========================================================

Explanation:

x = number of stickers Sally starts with

y = number of stickers Eric has

x/y is the ratio of the two values. This ratio is 3/5. So x/y = 3/5 which cross multiplies to 5x = 3y. We can divide both sides by 5 to end up with x = 3y/5

"Sally the bought another six stickers" meaning she starts with x and bumps up to x+6. Eric's sticker count stays the same. The ratio is now (x+6)/y. We can replace the x with 3y/5 and simplify

(x+6)/y = (3y/5+6)/y

(x+6)/y = (3y/5+30/5)/y

(x+6)/y = [ (3y+30)/5 ]/y

(x+6)/y = (3y+30)/(5y)

Now set this equal to the new ratio 9/10 and solve for y

(3y+30)/(5y) = 9/10

10(3y+30) = 9(5y) ... cross multiply

30y+300 = 45y

300 = 45y-30y

300 = 15y

15y = 300

y = 300/15

y = 20

Eric has 20 stickers. At this point you can stop as your teacher doesn't seem to want to know Sally's count. However, I'll keep going to show how to get that value.

x = 3y/5

x = 3*20/5 ... replace y with 20

x = 60/5

x = 12

Sally starts off with 12 stickers. Note how x/y = 12/20 = 3/5 meaning that the ratio x:y = 12:20 reduces to 3:5 (divide both parts by 4)

If we add 6 stickers to Sally's count, then she now has x+6 = 12+6 = 18 stickers. It leads to the ratio 18:20 = 9:10 (divide both parts by 2). So the answer is confirmed.
