The sequence here start out by adding 3 then 5 then 7
we see an increse of 2 to what we are adding so to get the next one we would add 2 to 7 to get 9 then add that to 22 to get 31

which of the following is the correct graph of the compound inequality 4p + 1&gt; -7 and 6p + 3 &lt; 33 ?
PtichkaEL [24]
<h3>Answer:  Choice C</h3>

============================================================

Explanation:

Let's solve the first inequality for p

4p+1 > -7

4p > -7-1

4p > -8

p > -8/4

p > -2

And we'll do the same for the second inequality as well

6p+3 < 33

6p < 33-3

6p < 30

p < 30/6

p < 5

----------------------

We've found that p > -2 and p < 5

This must mean -2 < p < 5

The graph of which consists of open holes at -2 and 5 on the number line, then we shade in between those open holes. The open holes are to indicate "do not include the endpoint as part of the shaded solution set".

We can say that p is between -2 and 5, excluding both endpoints.

So that's why graph C is the final answer.

Three workers sort 66 boxes in a day. One of the workers is three times more productive than the second worker and twice as prod
Lelechka [254]
1 worker =x

2 worker = \frac{worker1}{2}= \frac{x}{3}

3 worker = \frac{worker1}{3}= \frac{x}{3}

so:

66=x+ \frac{x}{3}+ \frac{x}{2}

66=x+\frac{2x}{6}+ \frac{3x}{6}

66*6=6x+2x+3x

396=11x

x=36

so:

worker 1 sorted 36 boxes
worker 2 sorted 18 boxes
worker 3 sorted 12 boxes

6(2 + v) – 4(2v + 1)​
eimsori [14]

Answer:

8-2v

Step-by-step explanation:

This is done just by opening the brackets and afterwards using bodmas or pemdas.

6(2 +v) - 4(2v +1 )

we start with paranthesis or brackets first.

12 + 6v - 8v - 4

then we collect the like terms(the ones that are compatible to be solved)

12 - 4 + 6v - 8v

8 - 2v

If you need any clarification or more explanation pls do mention at the comment section.

Hope this helps and if it does pls mark as branliest answer thx.
