Answer:
x = 3
Step-by-step explanation:
The triangles are similar.
x + 9 is twice 2x.
x + 9 = 2(2x)
x + 9 = 4x
9 = 3x
x = 3
Answer:
Side-Angle-Side similarity is what will tell you that ABD ≈AEC.
Step-by-step explanation:
Since ABE is isosceles, that means that AB=AE, and that angles B and E are equal. In the problem they tell you that BD is congruent to EC, so you have the three pieces of information that you need. The angle is between the two sides, so triangles ABD and AEC are congruent by Side-Angle-Side similarity.
Answer:
63.00
Step-by-step explanation:
Increasing a price by 50% is like adding half of the original price to get an updated price. 42 times 50% or divided by 2 (Since it produces the same result) is 21 and 21 plus 42 is 63. 63 dollars is the correct answer which means the correct option is option A.
Answer: $13.54
Step-by-step explanation:
This expression can't be solved because we don't know the value of e. Basically what this means is that e, an unknown number, is first being multiplied by 9, and it is then added by 10. You will just leave it as it is.
