Answer:
14
or 
Step-by-step explanation:
Turn your fractions into improper and make them have the same denominator
+
=
Leave it as is or simplify to 14
With the given data, the first step to take is to use MS excel to plot the data then determine the trendline in which the equation's r2 value is closest to 1. From the plot obtained from Excel, the plot is a second degree polynomial and not an exponential function. the answer hence is no.
Answer:
Associative property of addition
Step-by-step explanation:
The associative property of addition is as follows :
a+(b+c) = (a+b)+c
We have,
a = 8, b = 9 and c = 3
So,
Using above property,
(8+9)+3 = 8+(9+3)
20 = 20
Hence, this is the required solution.
Answer:
200
Step-by-step explanation:
1 decameter =10,000
so 2,000,000/10000=200
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
