No one got the correct answer. The answer is supposed to be 7(2d+3k-dk-1). All the coefficients are divisible by 7, thus only the integers are changed. However, the variables cannot be a factor because they do not have the same variables that all the coefficients must have.

How many numbers of solutions are there for the following equation<br> 2(4x+1) −5x +2 = 3x+4

soldier1979 [14.2K]

Answer:

infinite solutions

Step-by-step explanation:

2(4x+1) −5x +2 = 3x+4

Distribute

8x +2 -5x +2 =3x+4

Combine like terms

3x +4 = 3x+4

Subtract 3x from each side

3x-3x+4 = 3x-3x+4

4=4

This is always true, so there are infinite solutions

Kobotan [32]

Answer:

Probability of getting at least 9 out of 18 correctly is 0.0043

Step-by-step explanation:

We have

n = 18

p = 1/5 for correct answer

q = 4/5 for wrong answer

P( 9 $\leq$ X $\leq$ 18) = 1 - P(0 $\leq$ X $\leq$ 8)

= 1 - 0.9957

=0.0043
