You have 
of one type of coin and 
of another type of coin.
To find the total number of coins, you need to add the two values together.
Answer:
7
Step-by-step explanation:
pq - r/4
(-8)(-3) - 68/4
-8 x -3 = 24 (2 negatives equal a positive)
24 - 68/4
68/4 = 17
24-17 = 7
Answer: Systems of linear equations can only have 0, 1, or an infinite number of solutions. These two lines cannot intersect twice. The correct answer is that the system has one solution.
Step-by-step explanation:
3/16=5/x
times both sides by 16x (aka cross multiply
3x=5*16
3x=80
divide both sides by 3
x=80/3
x=26 and 2/3
the missing number is 80/3 or 26 and 2/3
You change the fraction so that they will have the same denominator. This makes it 5 6/8 minus 3/8. The answer is 5 3/8
