Answer:
9. x = 5
10. AD = 7
Step-by-step explanation:
As shown in the diagram, BD is a perpendicular bisector. And D is a point on the perpendicular bisector, meaning it is equidistant from the endpoints on the segment(points A and C). Because of this, we can say AD = CD.
We can substitute to get:
2x - 3 = x + 2
And simplify and solve:
x - 3 = 2
x = 5
AD is just 2x - 3, so we can substitute in x to find AD:
AD = 2(5) -3
AD = 10 - 3
AD = 7
Answer: 12/5 or 2.4
Step-by-step explanation:
4/5 in 20 minutes
4/5 times 3 = 12/5
20 times 3 = 60 minutes( 1 hour )
she can make 12/5 of a bracelet per hour or
Answer:
He is incorrect.
Step-by-step explanation:
The hundred-thousands digit is the 4.
To round to the nearest hundred-thousand, all digits to the right of 4 become zero.
The answer is either
3,400,000
or
3,500,000
The first digit to the right of the 4 is a 7, so the 4 rounds up to 5, and the answer is 3,500,000.
