Hello,
Please, see the attached file.
Thanks.
Lets look at the info we have:-
6 friends
Pay $90 and receive $42 in change.
Question:-
How much does each friend pay?
To answer this first we nee to find out how much they paed in total. lets do that 1st:-
90 - 42 = 48
They paid $48 for the gift.
CHECK OUR WORK:-
48 + 42 = 90
We were RIGHT!!
Now lets divide to find out how much each person paid:-
48 ÷ 6 = 8
Each friend pays $8.
CHECK OUR WORK:-
8 × 6 = 48
We were RIGHT!!
So, each friend pays $8 for the gift.
Hope I helped ya!! xD
Answer:
7/15
Step-by-step explanation:
0.4
6 = 0
.
6 - 0.2
0.46 = 6/9 ⋅ 0.9 - 0.2
0.46 = 6/9 - 1/5
0.46 = 2/3 - 1/5
0.46 = 10/15 - 3/15
0.46 = 7/15
Note that 7 and 15 have no common factors larger than 1
, so this is in simplest terms.
Answer:
7/2
Step-by-step explanation:
-4 and 2 are the solutions, since that is where they intercept the x axis, and when plugged into the equation, make it true.
