Question

plz help. Will give out medals.

Answer 1

A student solved this problem by working backwards.

Joani has some stuffed animals. She has 2 times as many as Lily. Lily has 6 stuffed animals. Joanie gave 2 away and bought 4 more. How many stuffed animals does Joani have now?

Students's solution: Lily has 6 stuffed animals, so Joani had 6 × 2 to begin with. So Joani had 12 stuffed animals. She gave away 2, so 12 – 2 = 10. She bought 4, so 10 + 4 = 14. So Joani has 14 stuffed animals.

Here is another problem that can also be solved by working backwards.

Wyatt has 3 times as many baseballs as golf balls. He has 5 fewer tennis balls than baseballs. Wyatt has 4 golf balls. How many tennis balls does Wyatt have?

Answer 2

So, if Lily has 6 stuffed animals and Joani has twice as many, how many does Joani have? Let's start with that.

\[6*2\]

Answer 3

12

Answer 4

Apologies, I was solving the wrong problem. That one was an example. Let's look at the baseball problem.

Wyatt has 3 times as many baseballs as golf balls.
\[b=3g\] (where b=baseballs and g=golf balls)

We know that he has 4 golf balls. Let's plug this in.

\[b=3(4)\] How many baseballs does he have?

Answer 5

2

Answer 6

How did you get that answer?

Answer 7

5-3

Answer 8

Why did you subtract 3 from 5? We are trying to find how many baseballs Wyatt has. The formula is up there, you just need to find b :)

Answer 9

just give me the answer

Answer 10

I can't do that, you must learn :)

Answer 11

the anwser to the whole prob. is 6

Answer 12

How did you figure that out?

Answer 13

worked it out

Answer 14

is it right

Answer 15

Okay, let's look at \[b=3(4)\] We just need to multiply 3 by 4. That's what the parenthesis means. \[b=12\] Now if t (tennis balls) is 5 less than b, what is t?

Answer 16

8

Answer 17

12
