Answer:
13 Quarters
Step-by-step explanation:
Let <u>D</u> and <u>Q</u> stand for the numbers of Dimes and Quarters.
We are told that:
D + Q = 31
We also find that:
D = Q + 5
Use the second expression (for D) in place of D in the first equation:
D + Q = 31
(Q+5) + Q = 31
2Q = 26
<u>Q = 13</u>
This means there are:
D = 13 + 5 or <u>18 Dimes</u>
======================
Check
D + Q = 31 ?
18 + 13 = 31 <u> YES</u>
D = Q + 5 ?
18 = 13 + 5 <u>YES</u>
The given values of abscissa and ordinate in the given are that which
when substituted to the values of x and y in the equation will make the
equation true. This means that the left and right-hand side of the equation
will be equal. The established equations should have a basis of,
x + y = c
The equations are,
x + y = 6
Substituting x = 7 and y = -1,
7 + (-1) = 6 ; 6 = 6
The other two equations will be,
2x + y = 13 and,
x + 2y = 5
It is to be noted that countless of equations can be made with the given
solution so long as the equation is valid.
x = All real numbers or 0.
First you should distribute both sides of the equation. This gives you 42x+42=42x+42.
Then, subtract 42 from both sides. This gives you 42x=42x.
Now, divide 42 on both sides. This gives you x=0 or all real numbers.
