Answer:
a) 7 days
b) 52 pictures
Explanation:
a) If p=pictures and she took 37 pictures, then plug in 37 into p, in the equation the solve.
If you have trouble solving the first step is to subtract 2 from both sides (both sides to cancel out the original 2, and so that 5d can be by itself).
37 = 5d + 2
-2 -2
35 = 5d
The final step is to divide 5 on each side to get d (the number of days by itself). Then you get the answer, d=7, which means that the number of days Lola spent on vacation if she took 37 pictures, would be 7 days.
35 = 5d
5 5
7=d or d=7
b) If d=days and she spent 10 days on vacation, then plug in 10 into d, in the equation then solve.
If you have trouble solving the first step is to multiply 5 by 10. Which will make you end up with 50 + 2
p = 5(10) + 2
p = 50 + 2
Then the final step is the add 50 and 2 together. This will get you the answer p=52, which means that the number of pictures Lola took for the 10 days she was on vacation would be 52 pictures.
Hope this helps!
