Answer: see below
Step-by-step explanation:
11.3x=15-2x
We move all terms to the left:
11.3x-(15-2x)=0
We add all the numbers together, and all the variables
11.3x-(-2x+15)=0
We get rid of parentheses
11.3x+2x-15=0
We add all the numbers together, and all the variables
13.3x-15=0
We move all terms containing x to the left, all other terms to the right
13.3x=15
x=15/13.3
x=1+1/7.8235294117647
Answer:
The longest sides is 18 m long.
Step-by-step explanation:
Let x meters be the length of the first side.
The length of the second side = x+9 m.
The length of the third = 3x m.
Perimeter = x + 3x + x + 9 = 39
5x + 9 = 39
5x = 30
x = 6 m.
The other 2 sides are 6+9 = 15 m and 3*6 = 18 m.
5 + 4 - 1 = 7
7 + 4 - 1 = 10
10 + 4 - 1 = 13
And so on
Answer:
50°
Step-by-step explanation:
An inscribed angle is half the measure of its intercepted arc. Here, arc AC is ∠B's intercepting arc. Arc AC is 100°, and 100/2 = 50, so ∠B is 50°.
