So, I would first see what the value would be if there was only one nickel.
.05+7(.1)=.75
Now divide 3.75 by .75 to see how many there would be:
3.75÷.75= 5
Now see if there was 5 nickels
5(.05)+35(.1)= .25+3.5=3.75
So there are 5 nickels and 35 dimes.
Hi!
Let's put the values in the equation.
10 · 5 + 16 ÷ 4 = ?
Using PEMDAS...
Multiplication
50 + 16 ÷ 4 = ?
Division
50 + 4 = ?
Addition
54
The answer is 54
Hope this helps! :)
Sarah is older than 44.
Her age, a, minus 44 is a positive number.
a - 44 is positive
4 times the difference is 4(a - 44)
That equals 64, so we have
4(a - 44) = 64
Divide both sides by 4
a - 44 = 16
Add 44 to both sides
a = 60
Sarah's age is 60.
Check: Sarah is 60.
The difference between Sarah's age and 44 is 60 - 44 = 16
4 times that difference is 16 * 4 = 64.
Our solution is correct.
