Answer:

Norma ate [tex]\frac{9}{32}[/tex] of the leftover cake at her lunch.

Step-by-step explanation:

Norma had a leftover cake from her party = [tex]\frac{3}{8}[/tex]

She ate [tex]\frac{3}{4}[/tex]th of the leftover cake at the lunch.

Therefore, amount of cake she had at lunch = [tex]\frac{3}{8}\times \frac{3}{4}[/tex]

                                                                          = [tex]\frac{9}{32}[/tex] of the leftover cake

Norma ate [tex]\frac{9}{32}[/tex] of the leftover cake at her lunch.

Answer:

Step-by-step explanation:

Let the number of small boxes = x

and the number of large boxes = y

Total number of boxes = 24

Therefore, equation will be,

x + y = 24 ------ (1)

Since, volume of the smaller boxes = 9 cubic feet

And the volume of larger boxes = 24 cubic feet

Therefore, total volume of the boxes = (9x + 24y)

Since combined volume of all boxes = 441 cubic feet

Therefore, equation will be,

9x + 24y = 441 ------ (2)

The expression equivalent to [tex]\frac{15}{x - 6} + \frac{7}{x + 6}[/tex] is (d) [tex]\frac{22x+ 48}{x^2 - 36}[/tex], if no denominator equals zero

The expression is given as:

[tex]\frac{15}{x - 6} + \frac{7}{x + 6}[/tex]

Take LCM of the above expression

[tex]\frac{15}{x - 6} + \frac{7}{x + 6} = \frac{15(x + 6) + 7(x - 6)}{(x - 6)(x + 6)}[/tex]

Expand

[tex]\frac{15}{x - 6} + \frac{7}{x + 6} = \frac{15x + 90 + 7x - 42}{x^2 - 36}[/tex]

Collect like terms

[tex]\frac{15}{x - 6} + \frac{7}{x + 6} = \frac{15x + 7x+ 90 - 42}{x^2 - 36}[/tex]

Evaluate the like terms

[tex]\frac{15}{x - 6} + \frac{7}{x + 6} = \frac{22x+ 48}{x^2 - 36}[/tex]

Hence, the expression equivalent to [tex]\frac{15}{x - 6} + \frac{7}{x + 6}[/tex] is (d) [tex]\frac{22x+ 48}{x^2 - 36}[/tex]
