Answer:
6.
Step-by-step explanation:
We can start by defining a couple things.
x = amount of nickels
y = amount of dimes
Since he has the same amount of each, we can say this.
x = y
And because we know it totals 0.90, we can say this.
0.05x + 0.10y = 0.90
then, we substitute and get this.
0.05x + 0.10x = 0.90
Simplify.
0.15x = 0.90
Divide both sides by 0.15.
x = 6
So we have 6 nickels, and they both are the same, so we have 6 dimes.
X ( a number) / (divided by) 2 (two)
A number divided by 2.
or
The quotient of a number, x, and 2.
Answer:
4 feet.
Step-by-step explanation:
Let x be the height of tower when finished.
We have been given that Priya takes a break when the tower is 2 and 1/2 feet tall, which is 5/8 of the height of the tower she wants to build.
This means that 5/8 of x equals 
. Let us represent this information in an equation.
Let us convert our given mixed fraction into improper fraction.
Let us multiply both sides of our equation by 8/5.
Therefore, the tower will be 4 feet tall when finished.
