Answer:
A
Step-by-step explanation:
5in=84in
scale factor is 16.8 (84/5)
(21x12)/16.8=15
(28x12)/16.8= 20
Step-by-step explanation:
12 . The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. Thinking about intercepts helps us graph linear equations..
the first step Andre made was
2x+6=3x-8
or, -x+6=-8
And the first step Diego made was
2x+6=3x-8
or, +6=3x-2x
or, 6=x-8
...
Answer:
Yes
Step-by-step explanation:
If you divide their time by 100 you will get the amount of time it takes the student to run 1 meter.
Ex. Time is 20 seconds.
20/100
0.2 meters/second

Answer:
B. x < 17
Step-by-step explanation:
x is a leg of right triangle ADC, so must have a length less than the hypotenuse. (x < 20)
x is a leg of triangle ABC, so must have a length between 20-17 = 3 and 20+17=37. The first restriction limits x to ...
3 < x < 20 . . . . . allows x ≥ 17
The Pythagorean theorem applied to the right triangle requires ...
x^2 +y^2 = 400
Angle ABC is opposite side AC, which has length 20. Angle BAC is opposite side BC, which has length 17. The longer length of AC means that angle B will always be greater than angle A in triangle ABC.
