Answer:
30
Step-by-step explanation:
Given the equation;
n/10 + 7 = 10
We are to find the value of n
Subtract 7 from both sides
n/10 + 7 - 7 = 10 - 7
n/10 = 3
Cross multiply
n = 10 * 3
n = 30
<em>Hence the solution to the equation is 30</em>

Answer:
34
Step-by-step explanation:
Let x represent the number of nickels Abby has. Then the number of dimes is 61-x. The total value of the coins, in cents, is ...
5x +10(61-x) = 440
-5x +610 = 440 . . . . . simplify
x - 122 = -88 . . . . . . . .divide by -5
x = 34 . . . . . . . . . . . . add 122
Abby has 34 nickels in her collection of coins.
Answer:
80% of the buttons were large.
Step-by-step explanation:
Recall that percentages are fractions.
We first need to find the total number of buttons that Eva bought
64 + 16 = 80
Then we need to divide 64 into 80 as a fraction of the whole (80 is our whole)
64 ÷ 80 = 0.8
To convert our decimal to a percentage, we must multiply it by 100.
0.8 * 100% = 80%
Therefore, 80% of the buttons were large.
