Eighths and their multiples are common fractions which I recommend memorizing, but to actually solve this, you use the literal meaning of a fraction and divide 5 by 8. See the long-division below (it was surprisingly difficult to type, so I hope it helps!).
To round 0.625 to the nearest hundredth, we go to the second decimal place, which is 5, so we round up to 0.63.
of means times so you multiply the fractions
1 x 9 = 9
3 x 16 = 48 (we multiplied numerators and denominators)
9/48 = 3/16 (Simplify by dividing a multiple on both the numerator and denominator
1) 32*10^4 is not written in scientific notation because the first factor is not a number betweem 1 and 10.
3.4 * 10^5 is the same number written in scientific notation.
2) 2.01x10^-5 is written in scientific notation.
Step-by-step explanation:
a. (x-2)^2 + (y+1)^2 = 16
b. (x + 2)^2 + (y-2)^2 = 9
The given equation is:
5x - 4y = 12
First take y term on one side. So we can write the equation as:
5x - 12 = 4y
or
4y = 5x - 12
Next divide both sides by 4 to isolate y. The equation thus becomes:
So, third option gives the correct answer
