Answer:

72

Step-by-step explanation:

If you take s + 19 = 8s - 100 , you will get 17, so s = 17. Plus 17 into 4s + 4 and you will get 72. DC = BE, so BE = 72.

Answer:

The answer is either 9, -9, 1, or -1

Answer:

Order equivalent equations of 2(x−3) = 4x to solve for x.

Step-by-step explanation:

So, to do this we must do distrubition so 2 times x = 2x -3 times 2 = -6 and 4x times 2 equals 6x and subtract the 6x from 6 which equals x sotherefore 2 and 2 cancels out so you're left with x=x

ANSWER: x=x

Answer:

49.

Step-by-step explanation:

Suppose we start with 12 people whose birth months are all different.

If there we add to make  13 people then we can say that at least 2 were born in the same month as there are 12 months in a year.

If we add another student then he could have the same month date as the other 2 but he is more likely to have another  birth month.

So we could go on adding 1 student 11 times and get 12 pairs of students with the same birth month.

This is very unlikely but possible.

Now we could also add 12 more and end up with 12 sets of 3 with same birth month.

Then another 12 giving 12 sets of 4.

Then the next student must be 1 of 5 with same month.

So that makes 49 students.

Answer:

No solution

Step-by-step explanation:

Answer:

No Solution

Step-by-step explanation:

to solve for 'x' distribute the 2 on the left side and the 5 on the right side:

17 + 16x - 10 = 10 + 25x - 9x

combine 'like terms':

7 + 16x = 10 + 16x

There is no value for 'x' that would ever make the two sides equal ∴

No Solution

The Greatest Common Factor of 20, 30, and 55 will be 5.

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

It is given that, the numbers 20, 30, and 55.

The biggest divide between the two numbers is the greatest common factor. List each number's prime factors before calculating its greatest common factor.

20=5×2×2

30=5×2×3

55=5×11

One 2 and one 3 are the same for  20, 30, and 55. We multiply them to obtain the GCF, so the GCF of 20, 30, and 55 is 5.

Since we frequently work with fractions and they are prevalent in daily life, the greatest common factors (GCF) are very helpful. A fraction or ratio can be successfully simplified by determining the GCF of the denominator and numerator.

Thus, the Greatest Common Factor of 20, 30, and 55 will be 5.

Answer:

James is paying $0.17 per ml.

Step-by-step explanation:

To get this answer you divide the amount purchased by the amount spent: 3.43/20

This will give you 0.1715, which rounds down to 0.17 (which is 17 cents)

Answer:

P(X<129) ≈ 0.8849

Step-by-step explanation:

I've attached a graph of the normal distribution to help you visualize the problem. To calculate this on a TI-84, we can use the normalcdf function to find the area between the end of the left-tail of the normal distribution to x=129, hence, we are finding P(X<129). We can write this as normalcdf(-1e99,129,105,20) ≈ 0.8849, therefore, the probability that a randomly selected adult has an IQ less than 129 is about 0.8849 or about 88.49% likely to occur.
