Is the expression 2 • 4 ^ x equal to the expression 8 ^ x ? Explain your answer

kkurt [141]

Answer:

It depends on the value of x

Step-by-step explanation:

If x=1, then yes

Exponents come before multiplication, so even if 2*4=8, 2*4^2 is not equal to 8.

Ex:

2*4^2=32

8^2=64

Estelle is helping at a community food drive by boxing up cans of soup. There are two sizes of boxes, large and small. Estelle f

podryga [215]

Answer:

The small box contains 21 cans

Step-by-step explanation:

Represent the small box with S and the large with L.

For Estelle:

$3L + 5S = 170$

For the boy:

$4L + 4S = 184$

Required

Determine the cans in the small box

$3L + 5S = 170$ --- (1)

$4L + 4S = 184$ --- (2)

Divide (2) through by 4

$L + S = 46$

Make L the subject

$L = 46 -S$

Substitute 46 - S for L in (1)

$3L + 5S = 170$

$3(46 - S) + 5S = 170$

Open bracket

$128 - 3S + 5S = 170$

$128 + 2S = 170$

Collect Like Terms

$2S = 170-128$

$2S = 42$

Divide both sides by 2

$S = 21$

Hence, the small box contains 21 cans

Jasper's lawn is 3/4 of an acre in size. The fertilizer bag states that 5 1/2 bags are required for 1 acre. How many bags does J

Nady [450]

Answer: $4\dfrac{1}{8}\ \text{bags}$

Step-by-step explanation:

Given

Jasper lawn is three-fourth of an acre

1 acre of land requires $5\frac{1}{2}$ bags

convert mixed numeral to fraction

$\Rightarrow 5\dfrac{1}{2}=\dfrac{11}{2}$

$\therefore 1\ \text{acre}\equiv\dfrac{11}{2}\ \text{bags}\\\\\Rightarrow \dfrac{3}{4}\ \text{acre}\equiv \dfrac{11}{2}\times \dfrac{3}{4}=\dfrac{33}{8}\ \text{bags}$

$\Rightarrow \dfrac{33}{8}\ \text{bags}=4\dfrac{1}{8}\ \text{bags}$
