Answer:
2,734,500
Step-by-step explanation:
27,345 × 113 - 27,345 × 13 ← factor out 27,345 from each term
= 27,345(113 - 13)
= 27,345 × 100
= 2,734,500
ANSWER
(6,-5)
EXPLANATION
The given system has equations:
2x + y =7...(1)
x- 2y = 16...(2)
We multiply equation (1) by 2 to get,
4x+2y=14...(3)
We add equations (2) and (3) to obtain,
4x+x+2y-2y=14+16
This implies that,
5x= 30
Divide both sides by 5,
x=6
We substitute x=6 into equation (1) to get,
2(6) +y=7
12+y=7
y=7-12
y=-5
The solution is (6,-5)
<span>9(t) + 3f(t) + 12.....t = 21 and f = 3
so we sub
9(21) + 3(3) x 21 + 12
= 390
hope this helps</span>

Answer: 20 sides</h3>
Work Shown:
E = exterior angle = 18 degrees
n = number of sides of a regular polygon
n = 360/E
n = 360/18
n = 20
This is a 20 sided regular polygon. It is considered a regular icosagon.
Answer:
60 mph?
Step-by-step explanation:
If she drives 320 miles in 5 hours, her average speed would be 64 mph, but 60 is the closest so I would go with that I guess. I'm pretty sure these are all wrong options though
