Tyrell has 6 coins, all of which are quarters and dimes. in all , they’re worth 90 cent how many of each kind of coins does terrell have

3 quarters and 1 dimes and 1 nickel

Step-by-step explanation:

first i put in 3 quarts since i now that going to be 75 then i try one dime then i knew that was less so then knew that was going to be over so than i try a nickel in that how i got it

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
