B is the midpoint of AC, what in the measure of AB if AC 82cm?​
Bess [88]

Answer:

AB = 41 cm

Step-by-step explanation:

If B is the midpoint of AC, then B splits AC into 2 equal halves: AB & BC.

Therefore, AB = ½ of AC.

Given, AC = 82 cm.

So,

AB = ½ × AC

AB = 82/2

AB = 41 cm

Omg help me please like I just can't right now <br><br> 2x-6y= -12 <br> x+2y=14
steposvetlana [31]

here,

2x-6y= -12

2(x-3y)= -12

x-3y = -6...........eq1

x+2y=14............eq2

we can subtract the above two given equations

we get,

x - 3y =  - 6 \\ x + 2y = 14

___________

- 5y =  - 20

so,

y=4

now to find the value of x we have to substitute the value of y in any of the above two equations, I choose eq2

we get,

x + 2y = 14 \\ x + 2 \times 4 = 14 \\ x + 8 = 14 \\ x = 14 - 8 \\ x = 6

<h3>so,</h3><h3> x=6,y=4</h3>
