Step-by-step explanation:

convert 2/3 to 4/6, then subtract from 5/6 to get 1/6. you then divide 1/6 by 1/5, leaving x.

Answer:

x = 5/6

Step-by-step explanation:

Solve for x by simplifying both sides of the equation, then isolating the variable.

Which of the fractions listed below are equal to 2⁄3?6⁄91⁄33⁄24⁄61⁄6

Usimov [2.4K]

6 / 9 = 2/3 ( since dividing top and bottom be 3 gives 2/3)

Also 4/6 = 2/3

the difference between 2 whole numbers is 66. the ratio of the 2 numbers is 2:5, what are the 2 numbers

shtirl [24]

Answer:

44 and 110

Step-by-step explanation:

The ratio of the 2 numbers = 2 : 5 = 2x : 5x ( x is a multiplier ) , thus

difference = 5x - 2x = 3x , then

3x = 66 ( divide both sides by 3 )

x = 22

Thus

2x = 2 × 22 = 44

5x = 5 × 22 = 110

The 2 numbers are 44 and 110

What is 92.9 rounded to the nersst whole number

sammy [17]

The nearest whole number would be 93 because you round up if the decimal place is greater than 5 and down if it's less.

There is a 30 percent chance that A can fix her busted computer. If A cannot, then there is a 40 percent chance that her friend

Solnce55 [7]

Answer:

(a) 0.70

(b) 0.40

Step-by-step explanation:

Mutually-exclusive events are those events which cannot occur together.

Consider that events X and Y are mutually exclusive.

P (X and Y) = 0

Here the two events can be defined as follows:

A = A can fix the busted computer

B = B can fix the busted computer

The information provided are as follows:

P (A) = 0.30

P (B) = 0.40

If A cannot, then there is a chance that her friend B can fix it.

The above statement suggest that the events A and B are mutually exclusive, i.e. if A can fix the computer then B does not have to and if cannot then only B will fix it.

That is, P (A and B) = 0.

(a)

Compute the probability it will be fixed by either A or B as follows:

P (A or B) = P (A) + P (B) - P (A and B)

= 0.30 + 0.40 - 0

= 0.70

Thus, the probability it will be fixed by either A or B is 0.70.

(b)

Compute the probability that if it is fixed it will be fixed by B as follows:

P (not A and B) = P (B) - P (A and B)

= 0.40 - 0

= 0.40

Thus, the probability that if it is fixed it will be fixed by B is 0.40.
