The answer to your problem is 58/90
Prob of just quarter is 3/14 for a dime is 4/14 and for a nickel its 7/14
then all you do is multiply them all together to get 306122449/<span>10000000000 that took me way to long</span>
Solution here,
dimentions of is 20 in. by 10 in. by 12 in.
i.e. volume of tank=20×10×12=2400 cu. in.
Again,
the tank holds 10 gallons of water
i.e. 10 gallons of water occupies 2400 cu. in.
so, 1 gallon of water occupies 2400/10 cu.in.
=240 cu.in
The first one would be C. <
The second would be neither because B.4a+8 equals 16 and 2(a+6) also equals 16
6 +- 4 is just 6 minus 4. 2
-8 -(-10) would be -8 plus 10. 2
-7 plus 3 would be -4
If these don't make sense to you, get a tutor. This is basic math
