Janet has a jar of 54 coins consisting of dimes and quarters. if she has a total of $8.70, how many dimes does she have? 22 24 30 32

32

Step-by-step explanation:

Let x  be the number of dimes and y be the number of quarters Janet has.

We know that 1 dime = $0.1

1 quarter = $0.25

Given : Janet has a jar of 54 coins consisting of dimes and quarters.

i.e.

She has a total of $8.70.

i.e.

Multiply equation (2) by 10 we get

Eliminate equation (1) from (3), we get

Put value of y=22 in (1), we get

Hence, she has 32 dimes.

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
