Answer:
I think it's C
Step-by-step explanation:
the right answer is 7 and 4 because the angles are between the two lines that are not the transversal and are on diagonal opposite sides of the transversal.
6(3x + 4) + 5(12-x) simplifies to
D) 13x + 84
162
+207
= 369
Okay, so it says he descends 285 feet after he's climbed 369 feet. That means he needs to descend a bit more to reach 453 feet, which we'll just call 0 for now. First, we need to do some subtraction:
369
- 285
= 84
Okay, we know he needs to descend 84 feet to get to his starting point.
So your answer is C
So k=katie's' age
m=mara's age
k is 2 times as old as m
k=2m
sum is 24
add means sum
k+m=24
so we have
k+m=24 and
k=2m
subsitute
2m+m=24
add
3m=24
divide both sides by 3
m=8
subsitute again
k=2m
k=2(8)
k=16
katie=16
mara=8
