Answer:
i believe the answer is D (which is 10)
Step-by-step explanation:
i just took the test. so you have to isolate X, so you add 2 to both sides and on the right you get answer of "5". so then you have to multiply both sides by "2/1" (which is the reciprocal of 1/2) and so on the left side so you're left with just "x", and on the right side you have 2/1 times 5/1 which equals "10".

Definition of an equilateral triangle: A triangle with the exact same sides and angles, which is 60°
<em>5 more than twice a number:</em>
Let the number be x:
2x + 5
<em>Since it is an equilateral triangle, multiply that by 3:</em>
3(2x +5) = 6x + 15
The perimeter is (6x + 15) inches.
1/8 multiplied by 2 will give you 16/8
