You should ask your parent/guardian
or teacher if needed! Merry Christmas!
Of means multiplication
So
![\frac{3}{4} \sf{of} \frac{16}{21} = \frac{3}{4} \times \frac{16}{21}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B4%7D%20%5Csf%7Bof%7D%20%20%5Cfrac%7B16%7D%7B21%7D%20%20%3D%20%20%5Cfrac%7B3%7D%7B4%7D%20%5Ctimes%20%20%5Cfrac%7B16%7D%7B21%7D%20)
And then simplify the numerator ad denominator
=
![\frac{3 \times 16}{4 \times 21} = \frac{\ 1 \times 16}{4 \times 7}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%20%5Ctimes%2016%7D%7B4%20%5Ctimes%2021%7D%20%3D%20%20%5Cfrac%7B%5C%201%20%5Ctimes%2016%7D%7B4%20%5Ctimes%207%7D)
And simplify the numerator and denominator again
=
![\frac{\ 1 \times 16}{4 \times 7} = \frac{\ 1 \times 4}{1 \times 7}](https://tex.z-dn.net/?f=%5Cfrac%7B%5C%201%20%5Ctimes%2016%7D%7B4%20%5Ctimes%207%7D%20%3D%20%5Cfrac%7B%5C%201%20%5Ctimes%204%7D%7B1%20%5Ctimes%207%7D)
And we are finally left with the answer which is
Answer:
![b=\frac{a}{2} +\frac{c}{2}](https://tex.z-dn.net/?f=b%3D%5Cfrac%7Ba%7D%7B2%7D%20%2B%5Cfrac%7Bc%7D%7B2%7D)
Explanation:
While solving literal equations could be quite overwelhming, simply solve it by using normal equation solving methods.
For example, if you were to solve 2x + 3 = 9
You would add 3 on both sides and divide both sides by 2 to determine x.
Do the same thing for literal equations, and if in doubts, plug in numbers to check your work.
Step-by-step explanation:
For this problem, add c on both sides, we do this because we are aiming to eliminate the c from both sides.
a+c =2b
In order to find the value of b, divide both sides by 2, we do this because we want to get rid of the coefficient.
This should leave you with the answer of b=a/2 + c/2
It’s either vertex or base
Answer:
90 in²
Step-by-step explanation:
The figure's area is that of four right triangles, each with legs of 6 in and 7.5 in. The area of each triangle is half the product of the leg lengths, so is ...
triangle area = (1/2)(6 in)(7.5 in)
Then the area of 4 of those triangles is ...
figure area = 4 · triangle area = 2(6 in)(7.5 in) = 90 in²
