Answer:

x = 4

Step-by-step explanation:

3x -5 = -2 + 9

-2 + 9 = 7 so now its 3x - 5 = 7

add 5 to the -5 so it cancels itself out. then add the 5 to 7 so it become 12. the you have 3x = 12

divide 12 ÷ 3 = 4

x = 4

The answer is x = 4.
3x - 5 = -2 + 9
add -2 + 9 and that gives you 7 so now
3x - 5 = 7 you add -5 on both sides but when you switch the -5 over with the 7 is becomes +5 so now you have 3x = 12 since 5 + 7 is 12
then you’ll divide 3 on both sides and that leaves you with x = 4

agasfer [191]

Answer:

The answer is "Option A and Option B".

Step-by-step explanation:

In question 1:

In all cases, the entire population is measured so that the actual medium discrepancy could be measured as well as an interval of trust cannot be used.

This issue would be that she calculated the ages with all representatives of both classes, such that she measured a whole population. It's not necessary.

In question 2:

When the p-value is 0.042. At 90% trust and 92% trust level 11 (p-value below 0.10 and 0.08) are not included. however the biggest confidence level of 92%. Consequently, the largest trust level where the 11 is Not included in the trust interval is 92% trust.

A car is traveling down a highway at a constant speed, described by the equation d=65t, where d represents the distance, in mile

Alexxx [7]

Answer:

Step-by-step explanation:

We are given an equation d = 65 t, where d represents the distance, in miles, that the car travels at this speed in t hours.

We know distance, speed and time relation

d = s * t.

Where d represents the distance, that the car travels at this speed in t at the speed s.

If we compare that relation with the given equation, we can see s = 65.

So,

a) The 65 tell us speed of 65 miles per hour in this situation.

b) Second part seems to be incorrect. Please check it again.

c) We are given distance = 26 miles.

Plugging d= 26 in the given equation.

26 = 65 t

Dividing both sides by 65, we get

26/65 = t

t= 0.4 hours.

So, it takes 0.4 hours or 0.4 * 60 = 24 minutes o travel 26 miles at this speed.

a company uses two vans to transport workers from a free parking lot to the work place between 7:00 and 9:00 am one van has 6 mo

k0ka [10]

So first, I would assign the small van a variable for how many people it can hold, or x.

So since it makes two trips,

2x

And since the other van can hold six more people,

2x + x + 6

And 57 people are transported:

3x + 6 = 57

We can then solve.

3x = 57 - 6

3x = 51

x = 17

So since we now know a small can hold 17 people, and we know that the larger van has 6 more seats, we can just say

17 + 6 = 23

So the large van has 23 seats.
