Answer:

Step-by-step explanation:

Take $139.50 and divide it by $15.50

139.50 / 15.50 = 9

Then take 9 and multiply it by 3 because there are 3 shirts per $15.50

9 x 3 = 27

You can buy a total of 27 shirts with $139.50

What is the value of the arithmetic series below?

xxTIMURxx [149]

Answer:

(A)-494

Step-by-step explanation:

Given the arithmetic series

$S_{19}=\sum_{k=1}^{19}4-3k$

The terms in the sequence are:

When k=1, 4-3k=4-3(1)=1
When k=2, 4-3k=4-3(2)=-2
When k=3, 4-3k=4-3(3)=-5

Therefore, the terms in the sequence are: 1, -2, -5, ...

First term, a =1

Common difference, d=-2-1=-3

The sum of an arithmetic series, $S_n=\dfrac{n}{2}[2a+(n-1)d]$

Therefore:

$S_{19}=\dfrac{19}{2}[2(1)+(19-1)(-3)]\\=9.5[2+18*-3]\\=9.5[2-54]\\=9.5*-52\\=-494$

The correct option is A.

Which expressions are equivalent to 4d+6+2d4d+6+2d ? Choose all answers that apply: Choose all answers that apply: (Choice A) A

Sliva [168]

Answer:

Options A and C are correct choices.

Step-by-step explanation:

We have been given an expression $4d+6+2d$ and we are asked to choose all the equivalent expressions from given choices.

Let us simplify our given expression.

$4d+6+2d=(4d+2d)+6$

$4d+6+2d=6d+6$

Let us see which of our given choices matches with our answer.

A. $2(3d+3)$

Upon using distributive property $a(b+c)=a*b+a*c$ we will get,

$2*3d+2*3$

$6d+6$

Therefore, option A is a correct choice.

B. $6(d+6)$

Upon using distributive property $a(b+c)=a*b+a*c$ we will get,

$6*d+6*6$

$6d+36$

Since this expression is not equivalent to our answer, therefore, option B is not a correct choice.

C. $(3d+3)+(3d+3)$

Upon removing parenthesis we will get,

$3d+3+3d+3$

Upon combining like terms we will get,

$(3d+3d)+(3+3)$

$6d+6$

Therefore, option C is the correct choice.
