Answer:
B. 39°, 106°, 43°
Step-by-step explanation:
The sum of angle measures in a triangle is 180°. Then the sum of angle expressions will be 180.
(3x +1) +(11x -4) +(5x -7) = 180
19x -10 = 180 . . . . . collect terms
19x = 190 . . . . . . . . add 10
x = 10 . . . . . . . . . . . divide by 19
__
Then the three angle measures are ...
- 3·10 +1 = 31
- 11·10 -4 = 106
- 5·10 -7 = 43
The appropriate choice is ...
B. 31°, 106°, 43°
Answer:
72.5mph
Step-by-step explanation:
There is an easy way to work this. Divide the miles he drove by 2 so that you know how much he drove in 1/5 hours.
29/2= 14.5miles driven in 1/5 hours
Now, just multiply that number by 5 so that you know how many miles he drove in 5/5 hours (one full hour).
14.5*5= 72.5miles
Answer:
B) (0,0); r=5
Step-by-step explanation:
A circle's standard form is (x-h)^2+(y-k)^2=r^2
The center is (h, k) and the radius is r.
So, here the center would be (0, 0) and the radius would be square root 25, or 5.

C. 3^9
Explanation: Look at the photo! Hope this helps :)
3^5(3^4)
=(3•3•3•3•3) + (3•3•3•3)
=3^9
*additionally, all other answer choices do not have the same product as 3^9, which is 19,683
2.5x + 2y = 336
x = 2y
2 equations, 2 unknowns, solvable
3.5x = 336
7x = 672
x = 672 / 7
x = 96
96 / 2 = y
y = 48
