Answer:

A pound of a JELLY BEANS cost $2.5

A pound of TRAIL MIX cost $1.5

Step-by-step explanation:

From the question, we can draw out two equations and solve them simultaneously.

We should make some mild assumptions to make it easier:

Let Jelly beans be j

Let Trail mix be t

Therefore, we can extract these equations.

5j + 3t =$ 17 ...........i

2j + 12t = $ 23...…..ii

Let's Multiply equation (I) by 4 so that we can easily eliminate.

20j + 12t = $ 68..... iii

Let equation (iii) minus equation (ii)

18j + 0t = $45

18j = $45

j = $45/18

j = $2.5

A pound of a JELLY BEANS cost $2.5

Let's substitute j= $2.5 in EQUATION (I) so as to solve for TRAIL MIX.

5j + 3t =$ 17

5(2.5) + 3t = 17

12.5 + 3t = 17

3t = 17 - 12.5

3t = 4.5

t = $1.5

A pound of TRAIL MIX cost $1.5

Answer:

1) = 10 \frac{2}{5}  =  \frac{52}{5}

2) =  \frac{252}{25}  = 10 \frac{2}{25}

Step-by-step explanation:

6 \frac{4}{5}  + 3 \frac{3}{5}  \\ (6 + 3) + ( \frac{4}{5}  +  \frac{3}{5} ) \\ 9 +  \frac{7}{5}  = 9 + 1 \frac{2}{5}  \\ 9 + 1 +  \frac{2}{5}  = 10 +  \frac{2}{5}

\boxed{\green{= 10 \frac{2}{5}  =  \frac{52}{5}}}

•◇•◇•◇•◇•◇•◇•◇•◇•◇•◇•

2 \frac{4}{5}  \times 9 \frac{2}{5} \\  \frac{14}{5}  \times 9 \times  \frac{2}{5 }

\boxed{\green{ =  \frac{252}{25}  = 10 \frac{2}{25}}}

Line AB contains points A (−1, 3) and B (5, 3). Line AB has a slope that is zero undefined positive negative
nydimaria [60]
It would be zero

See how the Y are the same so if you were to graph it you would get a flat line and it wouldn't be undefined cause that when the X has the same value.

I'm not sure of my answer I know that you have to multiply diagonally then add or subtract I'm not sure.

-18(1) = -18,right? 

4(3) = 12, right? 

-18 - 12 = -30

From the looks of it, we had to "Subtract" the outcome of each problem that we went over 

You're correct: -30 (option A.) would be your answer

Answers:

I can't give you all the answers, because that would be cheating. How ever, I will give you the first 5 answers.

Move the decimal so there is one digit to the left of the decimal point. The places the decimal moved would be the exponent for 10.

  1. 3.456*10^2
  2. 8.89*10^-3
  3. 2.35*10^5
  4. 2.35*10^-2
  5. 3.015⋅0
