1)you have to do 220miles multiplie by 7 divide by 4
OR
2)220miles divide by 4 multiplie by7
remaibders is the same thing ,the same answer
Answer:
1)x is 8.5 y is 1.6 b) y= 7.8 x=6.8
Step-by-step explanation:
1) you have to times 3.4 by 2.5 because if you ties 2 b 2.5 is 5. Then you have to do the opposite for y, you have to divide 4 by 2.5.
b) 10.8 / 2 is 5.4 so 15.6/2 is 7.8. 3.4 * 2 is 6.8
I think its this.
Marcos has 6 nickels and 9 quarters
<em><u>Solution:</u></em>
Let "n" be the number of nickels
Let "q" be the number of quarters
<em><u>Marcos had 15 coins in nickels and quarters</u></em>
Therefore, we can say,
number of nickels + number of quarters = 15
n + q = 15 -------- eqn 1
<em><u>He has three more quarters than nickels</u></em>
Number of quarters = 3 + number of nickels
q = 3 + n -------- eqn 2
Eqn 1 and eqn 2 represents the system of equations
<em><u>Substitute eqn 2 in eqn 1</u></em>
n + 3 + n = 15
2n + 3 = 15
2n = 15 - 3
2n = 12
<h3>n = 6</h3>
<em><u>Substitute n = 6 in eqn 2</u></em>
q = 3 + 6
<h3>q = 9</h3>
Thus Marcos has 6 nickels and 9 quarters
