Answer:
To make a high estimate for the sum of two fractions, find the commnon denominator and add them.
Step-by-step explanation:
To make a high estimate for the sum of two fractions in a word problem, rhe following steps are required.
Let the two fractions be represented as and
To perfrom the operation +
Step 1 : Check if the denominators of the fraction are same. If so then, then add the numerators directly by keeping the same denominator.
Step 2: If the denominators are different, then find the common denominator between the fractions and multiply them accordingly. Then perform the addition operation.
I believe you have to do a cross product formula.
2174/x = 28.19/100
If you are talking about the binomial being expanded then it would be:
8x^3 + 12x^2y + 6xy^2 + y^3
The y in the second term is not part of the exponent
And since you are raising the binomial to the third, you would be using the third row of Pascal's triangle.
Hope this helped!
Let n = cost of 1 notebook
Let p = cost of 1 pencil
Then,
3n + 4p = 8.5
5n + 8p = 14.5
You can solve for one variable in terms of the other and then substitute into the remaining equation.
3n + 4p = 8.5
+ 5n + 8p = 14.5
Multiply the top equation by -2 so that the p-containing terms cancel each other out:
-2(3n + 4p = 8.5)
+ 5n + 8p = 14.5
-n + 0 = -2.5
So after dividing both sides by -1, we see that n = $2.5. Plugging into the first equation gives p = $0.25.
3n + 4p = 8.5
5n + 8p = 14.5
