Hello!

Find the cost of each individual item.

1.28 / 2 = 0.64

Each roll of tape costs $0.64.

0.87 / 3 = 0.29

Each notebook costs $0.29.

Each highlighter costs $1.59.

1.98 / 2 = 0.99

Each pen costs $0.99.

One roll of tape is $0.64, two notepads are $0.58 two highlighters cost $3.18, two pens are 1.98.

Add them up: .

0.64 + 0.58 + 3.18 + 1.98 = 6.38

ANSWER:

You would pay B. $6.38.

We have to determine what it costs for one single item and then divide or multiply by the quantity needed.

1 roll Tape= $1.28÷2= $0.64

2 rolls Notepads= 0.87÷3= 0.29x2= $0.58

2 Highlighters= $1.59x2= $3.18

2 Pens= $1.98

Add these totals:
+0.64
+0.58
+3.18
+1.98
=$6.38

ANSWER: B) $6.38

Hope this helps! :)

Jill can run a mile in 8 minutes. write an expression that represents the time it takes her to run m miles.
shtirl [24]
Hello,

The answer should be "8=m".

Reason:

Since it takes 8 minutes to run 1 mile put that first:

8

Since how 8min equal 1 mile you put equal

8=

Since how it could be more miles but m

8=m

If you need anymore help feel free to ask me!

Hope this helps!

Find d for the arithmetic series with S17=-170 and a1=2
Irina18 [472]
So, we know the sum of the first 17 terms is -170, thus S₁₇ = -170, and we also know the first term is 2, well

\bf \textit{ sum of a finite arithmetic sequence}\\\\
S_n=\cfrac{n(a_1+a_n)}{2}\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
----------\\
n=17\\
S_{17}=-170\\
a_1=2
\end{cases}
\\\\\\
-170=\cfrac{17(2+a_{17})}{2}\implies \cfrac{-170}{17}=\cfrac{(2+a_{17})}{2}
\\\\\\
-10=\cfrac{(2+a_{17})}{2}\implies -20=2+a_{17}\implies -22=a_{17}

well, since the 17th term is that much, let's check what "d" is then anyway,

\bf n^{th}\textit{ term of an arithmetic sequence}\\\\
a_n=a_1+(n-1)d\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
d=\textit{common difference}\\
----------\\
n=17\\
a_{17}=-22\\
a_1=2
\end{cases}
\\\\\\
-22=2+(17-1)d\implies -22=2+16d\implies -24=16d
\\\\\\
\cfrac{-24}{16}=d\implies -\cfrac{3}{2}=d
