Find the first six terms of the sequence.

aleksandrvk [35]

It's b. -1,-2,-4,-8,-16,-32
because
$a_n=2a_{n-1} \mbox{ where } a_1=-1.\\
So\\
a_2=2a_1=-2\\
a_3=2a_2=-4\\
a_4=2a_3=-8\\
a_5=2a_4=-16\\
a_6=2a_5=-32.$

The expressions a(8x+7) and 4x+3.5 are equivalent. What is the value of a?

valentina_108 [34]

Answer:

a=1/2

Step-by-step explanation:

From the question, the expression a(8x+7) is equivalent to 4x+3.5

Which means that multiplying 8x by a gives 4x and multiplying 7 by a gives 3.5

So, we can write the following to find the value of a

$a(8x+7)\equiv 4x+3.5$

we can write the following

8ax=4x

$\implies a=\frac{4x}{8x}= \frac{1}{2}$

Hence the value of a is 1/2

Erin buys a bag of peanuts that weighs 3/4 of a pound.Later that week, the bag is 2/3 full.How much does the bag of peanuts weig

dusya [7]

So he started with 3/4 lb and ended up with 2/3 of that so 2/3 of 3/4

'of' can be roughly translated as multiply

so 2/3 times 3/4 =6/12=1/2 lb left

or you know that there are 3 out of 4 parts pound left so 2 out of 3 parts of nuts is = 2/4 or 1/2 lb
