Is w = 8 a solution to the equation 5 + w = 58? Explain

Mathematics
1 answer:
sp2606 [1]3 years ago
8 0

No.

Since w = 8, you must replace the variable with the number associated to it.

So, it would be 5 + 8 = 58

5 + 8 is not equal to 58, it is equal to 13.

If you wanted to find out what w was, simply subtract 5 on both sides.

w = 58 - 5

How many different simple random sampmes of size 5 can be obtained from a pppulation whose size is 43?​
Nesterboy [21]

Answer:

Number of random samples = 962598

Step-by-step explanation:

A random sample represents  the responses for a certain survey of a part of the population.

A sample size is the part of the population being surveyed.

For a population N the number of different random samples that can be chosen for a sample size x can be calculated as = NCx

This can be calculated as :

NCx=\frac{N!}{x!(N-x)!}

Given:

Population size = 43

Sample size = 5

Number of random samples = 43C5

⇒ \frac{43!}{5!(43-5)!}

⇒ \frac{43!}{5!(38)!}

⇒ \frac{43\times42\times41\times40\times39}{5\times4\times3\times2\times1}    [Canceling out the common terms]

⇒  962598   (Answer)

Somebody please help me on multiple step equations with parenthesis.
mash [69]

Answer:

k = 8

Step-by-step explanation:

8(10 - k) = 2k

First, distribute within the parenthesis,

80 - 8k = 2k

Add 8k to both sides of the equation

80 = 10k

Divide both sides by 10 to get your answer

8 = k

I hope this helps :)

Easiest question in the world no joke this time

Question #25:

One way to solve this is by multiplying the number of packages per serving by the number of guests.

1/4 * 16 = 4 packages to serve 16 guests. This means he doesn't have enough.

A second way to solve this is by diving the number of packages by the number of packages it takes to make on serving.

3 1/2 ÷ 1/4 = 14 guests he can serve. This means he doesn't have enough.

Question #26:

First, find common denominators.

2/3 = 8/12

1/4 = 3/12

Second, subtract.

8/12 - 3/12 = 5/12

Therefore, the tank is 5/12 full at the end of the trip.

Question #27:

1/2 is cut off then 1/3 is cut off. This means 3/6 was cut off to bundle newspapers, then 1/6 was cut off to make parcel. In all, 4/6 was cut off the original string. Afterwards, 2/6 was left over. So, just multiply; 2 * 3 = 6.

Therefore, the original string was as a total of 6 meters.

Best of Luck!
