Hi, What is the lowest positive integer greater than 1, which when divided by 5 or 8 leaves a remainder of 1

1 answer:

3 0

Very interesting question!

Let's try to get something that would work for just 5 for now.
Any of these numbers would leave a remainder of 1 when divided by just 5:
6, 11, 16, 21, 26, 31, 36, 41, 46, 51, 56, 61, 66, 71, 76, 81, 86, ...
Notice that they all look like 5*(something) + 1. Basically, they are all multiples of 5 plus 1.

Let's see what would work for just 8:
9, 17, 25, 33, 41, 49, 57, 65, 73, 81, 89, ...

Are there any matches... AHA! It's 81. This is the lowest positive integer greater than 1 that follows the rule for both 5 and 8.

1*-5

2x²-10x+x-10 add numbers that have similar variables

-2x²-10x+x-10

=[-2x²-9x-10]

A smoothie recipe calls for 13 cup yogurt for each smoothie. How many cups of yogurt are needed to make 7 smoothies?

You could also say.
13 x
--- = ---
1 7
Multiply across.
1x=13×7
1x =91
Divide both sides by one.
x=91.
91 cups of yoygurt are needed to make 7 Smoothies.
Or you could do it the easy way.

I think the coordinates are 1, 10 but not positive because if you graph it you can see a kite in it so make the point close to 4,10
