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:
Agree.
Step-by-step explanation:
1. (5^r)^t can be represented simply as 5^rt.
2. when r as negative integer, t as positive integer, rt is always a negative integer
3. when ever the indices rt is negative, the number 5^rt will be less than 1, thus cannot be a whole number for sure.
Answer:
x=0, x=2, x=3

Answer:
R = 
Step-by-step explanation:
I = 
( multiply both sides by 100 to clear the fraction )
100I = PRT ( isolate R by dividing both sides by PT )
= R
The multiplicative inverse of -1/3 is -3.
The product of a number and it’s multiplicative inverse equals 1.
So... -1/3 x -3/1 = 1
A negative times a negative equals a positive.
