Allison bought jelly beans to share with her friends. She bought pounds of blueberry jelly beans and pounds of lemon jelly beans

Vaselesa [24]

Answer: $1\dfrac{11}{12}\text{ pounds}$

Step-by-step explanation:

The complete question is provided in the attachment.

Given, Amount blueberry jelly beans= $1\dfrac{1}{4}$ pounds

$=\dfrac{5}{4}$ pounds.

Amount lemon jelly beans = $2\dfrac{1}{3}$ pounds

$=\dfrac{7}{2}$ pounds

Total jelly beans she bought = Amount blueberry jelly beans + Amount lemon jelly beans

$=(\dfrac{5}{4}+\dfrac{7}{3})$ pounds

$=\frac{15+28}{12}\text{ pounds}\\\\=\dfrac{43}{12}\text{ pounds}$

Amount of jelly beans she gave away = $1\dfrac{2}{3}=\dfrac{5}{3}\text{ pounds}$

Amount of jelly beans she has left= Total jelly beans - Amount of jelly beans she gave away

= $\dfrac{43}{12}-\dfrac{5}{3}\\\\=\dfrac{43-20}{12}\\\\=\dfrac{23}{12}\\\\=1\dfrac{11}{12}\text{ pounds}$

She has left $1\dfrac{11}{12}\text{ pounds}$ of jelly beans.

PLEASE HELP!! Which equation matches the table of values?

RoseWind [281]

The equation that represents the table of values is $y=(\frac{1}{4})^x$

Step-by-step explanation:

We need to find the equation that matches the table of values.

x y

0 | 1

1 | 1/4

2 | 1/16

3 | 1/64

So, when x =0 y=1 and when x=1, y=1/4

if $y=(\frac{1}{4})^x$

then putting x=0 we get y=1

x=1, we get y=1/4

x=2, we get y=1/16

x=3, we get y=1/64

So, the equation that represents the table of values is $y=(\frac{1}{4})^x$

Kindly check your options, as option D should be $y=(\frac{1}{4})^x$
