Answer 2

A student solved this problem by working backwards.

Riley has some gerbils. He has 4 times as many as Lukas. Lukas has 2 gerbils. Riley gave 5 away and bought 2 more. How many gerbils does Riley have now?

Students's solution: Lukas has 2 gerbils, so Riley had 2 × 4 to begin with. So Riley had 8 gerbils. He gave away 5, so 8 – 5 = 3. He bought 2, so 2 + 3 = 5. So Riley has 5 gerbils.

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

Maddy picked 2 times as many tomatoes as carrots from her garden. She picked 4 fewer cucumbers than tomatoes. Maddy picked 5 carrots. How many cucumbers did Maddy pick?

Answer 3

Ok, you need to translate this into maths... You will get a few equations from this.
To simplify things, i have made carrots Ca, tomatoes T, and cucumber Cu

Answer 4

the amount of T is twice that of Ca, so Ca=2T

Answer 5

did u read the problem

Answer 6

Yes?

Answer 7

well they not asking for no letters

Answer 8

It should be 2Ca=T

Answer 9

I'm using letters as this can be solved algebraically

Answer 10

its no algedra

Answer 11
