Can someone please answer A and B please?
marta [7]

2 bags

7 apples


A) Instead of a lets say:

a = 1, 2 , 3

If a =1  then, (you already know there are 2 bags) you have 1 apple in each bag, making total of 2 apples

If a =2 then you are having 2 apples in each bag making total of 4 apples

If a =3, 3 apples in each bag, making total of 6 apples

Conclusion:

2 * 1 = 2

2 * 2 = 4

2 * 3 = 6

See the difference & pattern here

Now lets do with a

2 * a = 2a


B) If a = 6

then,  2*6 = 12

lets continue from a =3

2*4=8

2*5=10

2*6=12

See the pattern again


Tip: Drawing making problem understand better.

Vsevolod [243]

Answer:

The result is

\frac{5}{2}

Or

2.5

Step-by-step explanation:

We want to simplify

\frac{5}{8}  \times 4

We know that 4 goes into 8 twice.

This implies that:

\frac{5}{8}  \times 4 =  \frac{5}{2}

We can convert the result into decimals as follows:

\frac{5}{2}  =  \frac{25}{10}  = 2.5

Lydia graphed ΔDEF at the coordinates D (−2, −1), E (−2, 2), and F (0, 0). She thinks ΔDEF is a right triangle. Is Lydia's asser
alukav5142 [94]

Answer:

No; the slopes of segment EF and segment DF are not opposite reciprocals.

Step-by-step explanation:

The slope between two points O(e, f) and X (g,h) is given as:

slope\ of\ |OX|=\frac{h-f}{g-e}

The slopes of segment EF and segment DF are given below:

slope\ of\ |EF|=\frac{0-2}{0-(-2)}=-1\\\\slope\ of\ |DF|=\frac{0-(-2)}{0-(-1)}=2\\

For triangle DEF to be a right triangle, DF and EF are supposed to be perpendicular to each other. Two line are said to be perpendicular if the product of their slope is -1, i.e the slope of one line is the negative reciprocal (opposite reciprocal) of the other line.

Since the slope of DF and EF are not opposite reciprocals,  ΔDEF is not a right triangle.
