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

$\frac{5}{2}$

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.
