7. Lauren has a purse full of dimes and quarters. She has 25 less dimes than
quarters. If she has a total of $10.45,
which system of equations would she
write to find the number of dimes, d
and quarters, ?
d + 9 = 25
.10d +.259 = 10.45
A. REI.6-1 - So
by Graphing
d + 9 = 25
.25d +.107 = 10.45
Show Step-
9 -d = 25
.10d +.259 = 10.45
o
d- 9 = 25
.100 + 259 = 10.45
O

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

answer: 10 meter

step-by-step explanation:

need details

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
