one may note that 1 CC, Cubic Centimeter, or 1 cm³, is actually equivalent to 1 mL, milliliter.
so 2 cc = 2 mL.
Answer:
According to my very precise calculations, I've come to the conclusion that the answer is 1.
Answer:
7
Step-by-step explanation:
6x + 20 = 10x - 8
20 + 8 = 10x - 6x
28 = 4x
28 ÷ 4 = x
7 = x
Since you have two unknowns, you must formulate 2 equations in order to solve the system. Let x be the numbers of dimes and y be the number of quarters. The equations are:
x + y = 61
y = x + 3
Since a dime is 1/10 of a dollar and a quarter is 1/4 of a dollar,
(1/10)x + (1/4)y = 10.90
We made 3 equations. The system is overspecified. Let's just use the first two equations and apply it to the third for verification.
x + (x + 3) = 61
Solving for x,
x = 29
y = 29 + 3 = 32
Verifying,
(1/10)(29) + (1/4)(32) = 10.90
Hence, there are 29 dimes and 32 quarters.
