L 2.5.3 Quiz: Adding and Subtracting Unlike Fractions
nlexa [21]
I think that the answer is 51/54.
First you need to find the common denominator of both fractions, 54.
1/9 is 6/54 and 5/6 is 45/54. 45+6=51. And the denominator goes on the bottom,making the answer 51/54.
Hope this helps!

Answer:

16

Step-by-step explanation:

Subtracting the given expressions, that is

3b² - 8 - (b(b² + b - 7) ) ← simplify parenthesis

= 3b² - 8 - (b³ + b² - 7b) ← distribute parenthesis by - 1

= 3b² - 8 - b³ - b² + 7b ← collect like terms

= - b³ + 2b² + 7b - 8 ← substitute b = - 3

= - (- 3)³ + 2(- 3)² + 7(- 3) - 8

= - (- 27) + 2(9) - 21 - 8

= 27 + 18 - 21 - 8

= 16

In the given right triangle, find the length of the hypotenuse, AB, if BC = 6 and AC = 5.
wolverine [178]
*Use the Pythagorean Theorem

a^2 + b^2 = c^2

6^2 + 5^2 - c^2
36 + 25 = c^2
61 = c^2     *Square root 61

c^2 (c squared) = about 7.8

Round the fraction 7 4/5 to the nearest whole number
AnnyKZ [126]
The nearest whole number is <span><span>8</span></span>

When we are looking at rounding, we round to the number that our fraction or decimal is located. So, since we are rounding to the nearest whole number, given our original mixed number (7 \frac{4}{5}) our answer will be either 7 or 8.

We can change7 \frac{4}{5} to a decimal to equal 7.8 by multiplying both our denominator and our numerator by 2 since 5 * 2 =10, which would change our fraction to \frac{8}{10} which is the same thing as .8

If we look at 7.8 and want to know if it is closer to 8 or 7, we just remember that when rounding, if it is 5 or above, you round up, anything else, you leave the number in front of it like it is. .8 is above 5 so we round 7 to the whole number 8. So, our answer is 8

Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if I can help you further! :D

The area of a rectangle is 8x3 + 6x2 - 10x. The width of the rectangle is 2x. Find the length of the rectangle.
Sladkaya [172]
2x multiplies to all numbers:
2x x 8x3 = 16x4
2x x 6x2 = 12x3
2x x -10x = -20x2

Answer: 16x4 + 12x³ - 20x²

Hope this helps :)
