Please answer this question I have for you now

A. 10

Brainliest, please!

Step-by-step explanation:

(1, 2)(x, 5) = 1/3

5 - 2 / x - 1 = 1/3

3 / x - 1 = 1/3

x - 1 = 3 / 1/3

x - 1 = 9

x = 9 + 1

x = 10

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
