PLS HELP ASAP PLZ PLZ PLZ

Mathematics
1 answer:
KIM [24]3 years ago
6 0
I am unsure about the very last problem but I can help with the first two

1) (y+1)+4

If we combine the numbers 1 and 4, we get +5 and can isolate the numbers from the variable.

This would give us

y + 5 =

2) (6*r)*7

remember that we do not have to explicitly state 6*r

Instead, we can write it as 6r

this helps us get rid of the parentheses

now we can write it as 6r * 7=

I hope this helps!:)

You want to buy an item that costs $100. Which of these is the most cost-effective choice for buying the item?
stiv31 [10]
Buying it 10% discount without tax is the best option. With card you still have the tax plus the card fee you pay annually to add to it. On the online purchase, you still have the tax plus the 5 shipping charge.
