Kari picked 23 bunches of flowers from her garden. Each bunch had the same number of flowers. After she gave 46 flowers away, sh
Aleks [24]

Answer:

8 flowers in each bunch

Step-by-step explanation:

From this information, we can make the equation:

23b-46=138

Where b is the number of flower in each bunch.

23b-46=138

<em>Add 46 to both sides</em>

23b=184

<em>Divide both sides by 23</em>

b=8

There are 8 flowers in each bunch.

A line passes through the point (-8, 2) and has a slope of -1
Zanzabum

Answer:

y=-x-6

Step-by-step explanation:

Plug this into the equation y-y1=m(x-x1) where m is the slope. We know that it passes through (-8,2) so y1=2 and x1=-8. We also know that the slope is -1 so we can now fill in the equation. y-2=-1(x--8). We can change x--8 to x+8 so y-2=-1(x+8). Simplify this to get y-2=-x-8. You want to isolate y so you have to add 2 on both sides. y=-x-6. Therefore, the equation is y=-x-6.

If the average (arithmetic mean) of 3a and 4b is less than 50, and a is twice b, what is the largest integer value of a?
sdas [7]

Answer: The largest value of 'a' is less than 20

Step-by-step explanation:

If arithmetic mean of 3a and 4b is less than 50 i.e 3a+4b/2 < 50

3a+4b < 100... (1)

If a is twice as b, a = 2b... (2)

Substituting equation 2 into 1 we have, 3(2b)+4b < 100

6b+4b < 100

10b < 100

b < 10

Since a = 2b, a = 2×10 = 20

Therefore the largest value of 'a' is less than 20 which can be 19.9
