Do a proportion.
5/32= x/800
Cross multiply and divide
800 x 5= 4,000
4,000 divided by 32= 125
So answer is 125 students

Answer: 1.25
Step-by-step explanation: $15/$12= $1.25
$25/$20= $1.25
$35/$28=$1.25
To find constant proportionality you do your x value divided by your y value hoped this helped!
Answer:
2NaBr + CaF2 --> 2NaF + CaBr2 gives you:
2Na 2Na
2Br 2F
1Ca 1Ca
2F 2Br
This is balanced.
Step-by-step explanation:
2,1,2,1.
In a balanced chemical equation, the number of particular atoms on the right side of the equation is equal to the number of that atom on the left side of the equation.
As in the left side of the equation, there are 2 F atom and 1 Br. While on the right side there are 1 F and 2 Br. S for the balancing, we will put coefficient to the equation.
And the equation will be:
2NaBr + CaF2 → 2NaF + CaBr2
