The mean weight of 3 people in a lift was 68kg. If 2 of them weighed 58kg each, how much did the third person weigh?
rusak2 [61]

Answer:

88kg

Step-by-step explanation:

Mean= sum of weights/ Number of people

or, 68= 58+58+x/3

or, 68 * 3= 58+58+x

or, 204=116+x

or, x= 204-116

or,x= 88

Therefore, the weight of third person was 88 kg

Which point would be a solution to the system of linear inequalities shown below? {see image for inequalities}
stepan [7]

Answer:

(10, -2)

Step-by-step explanation:

The inequalities are:

y < x - 7               (1)

y < (1/5)x - 2        (2)

To solve this problem, we have to solve both equations simultaneously and then find the value of x and y that makes the inequality true.

To solve the inequality, subtract inequality (2) from inequality (1) which gives:

0 < (4/5) x - 5

-(4/5)x < -5

Dividing both sides of the equation by -4/5 gives:

-(4/5)x / (-4/5) < -5/ (-4/5)

x > 6.25

Put x > 6.2 in inequality 1

y < 6.25 - 7

y < -0.75

The solution of the inequality is x > 6.25 and y < -0.75

From the list of option, the correct answer is (10, -2) since 10 > 6.25 and -2 < -0.75
