You first have to make an simple equation.
= How many pennies
= How many quarters
After that, since a penny is 5 Cents and a quarter is 25 Cents, we make the equation as:
(cents)
To write the whole entire thing in an equation is:
Since I brought the x from the left to right, we change the positive "" to negative ""
To bring the '' to , we get rid of the ""s from both equations.
Now, you are left with the simplified equation:
Now you find the .
= 28
Conclude:
So the y was the quarter and the x was the pennies.
Quarters = 13
Pennies = 28
Answer:
A. 8
Step-by-step explanation:
1kg=2.2
18.5 lbs= 8kg
A= 9
B= 11
Make sure to try it
The primes in the set [1,10] are 1,2,3,5,7 and the number of elements is 10 so
(5/10)(4/9)=20/90=2/9
which for some reason they converted to 4/18 :P
