3. Diego needs to grow 3.62 inches

Step-by-step explanation:

Work through numbers one and two like basic addition and subtraction.

Number three is a little more tricky becuase is is a word problem. Since Diego needs to be 39.37 inches tall, but he's only 35.75 inches tall, you can do this.

39.37

-35.75

-----------= 3.62 inches.

A handy way to think of addition and subtraction with decimals, is to take the decimals out, do the problem that way, and add the decimals right back in after you have worked the problem.

If you need help learning more about addition and subtracting with decimals, dont be afraid to ask your parents and your teachers.

PLEASE HELP! A positive number is 1/3 of another number. The sum of the numbers is five less than the square of the larger numbe

Answer: The numbers are 1 and 3.

Step-by-step explanation:

Let x = smaller number , y= larger number.

As per given,

$x=\dfrac{y}{3}$ ...(i)

$x+y=y^2-5$ ...(ii)

Put value of x from (i) in (ii)

$\dfrac{y}{3}+y=y^2-5\\\\\Rightarrow\ \dfrac43y=y^2-5\\\\\Rightarrow\ 3y^2-4y-15=0\\\\\Rightarrow\ 3y^2-9y+5y-15=0\\\\\Rightarrow\ 3y(y-3)+5(y-3)=0\\\\\Rightarrow\ (y-3)(3y+5)=0\\\\\Rightarrow\ y=3 \ \ or\ y=\dfrac{-5}{3}$
