Answer:
40
Step-by-step explanation:
If you look at the ratios you can see the pattern of the first number being multiplied by 4 everytime. Therefore you must multiply 10 by 4.
Add 3.26d+9.75-2.65
13.01y - 2.65
139 thats all i can tell you because i cant write it out unless you want me too explain it by writing it
The number of half dollars coins are 5 and the number of the quarters dollars coins are 12.
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
You have a cup with 17 coins inside.
The total inside the cup is $5.50.
Let x be the number of half dollars and y be the number of the quarters dollars.
Then the equations will be
x + y = 17 ............1
0.5x + 0.25y = 5.5 ...........2
By solving equations 1 and 2, we have
x = 5 and y = 12
