Mathematics
1 answer:
Taya2010 [7]2 years ago
6 0

Answer:

<h2>x = ∞</h2>

Step-by-step explanation:

Given the expression 4x-1 = 4x+7, we are to simplify the expression and find the value of x. To do that the following steps must be carried out.

Step 1: collect the like terms by regrouping the expression

4x-1 = 4x+7

4x - 4x = 7+1

0x = 8

Step 2: Dividing both sides by the number next to x

0x/0 = 8/0

x = ∞

<em>Any constant dividing zero will always return infinity as a value. </em>

GenaCL600 [577]

Answer:

59 / 71

Step-by-step explanation:

Given the data :

A B C Total

Male 20 10 13 43

Female 15 2 11 28

Total 35 12 24 71

The probability of randomly selecting a Student that got B ;

Probability = required outcome / Total possible outcomes

P(getting B) = number of students who got B / total number of students

P(getting B) = 12 / 71

Probability of getting B = 12 /71

Probability of not getting B = P(getting B)' = 1 - P(getting B)

Probability that student did not get "B" = 1 - 12/71 = 59 / 71

The Italian size of a suit jacket is N centimeters, where N is the linear distance between the armpits. The American size of a s
Gekata [30.6K]

Answer:

B) 47

Step-by-step explanation:

Given:

N = linear distance between the armpits in cm

2.5P = 2N

or

P = (2 ÷ 2.5)N

or

P = 0.8N         ................(1)

also,

N = P + 10,

substituting the value of P from (1) we get

N = 0.8N + 10

or

N - 0.8N = 10

or

0.2N = 10

or

N = 10 ÷ 0.2

or

N = 50

Hence

the value is closest to option (B) 47
