Answer:
I know a little of this
Step-by-step explanation:
ok so what you do is for example take both of the small equation with the same variable and equal them to each other then plug in to the other
ex. 7x-31 =5x-8 solve this the plug what you get into the y in equation 4(y) +27
150 x 12 = 1800
55 x 12 = 660
1800 + 660 + 45000 = 47,460
13 cm (approximately)
Step-by-step explanation:
Let the radius of the circle be 'r'.
Area of the circle = πr²
=> 132.7 = (22/7) r²
=> 6.5 ≈ r
Therefore, diameter = 2radius = 2(6.5) = 13 cm
Answer:
Each hour he fly 107.76 miles
Step-by-step explanation:
we know that
Charles Lindbergh flew 3,610 miles in 33.5 hours
To find out the unit rate, divide the total distance by the total time
so
therefore
Each hour he fly 107.76 miles
Step-by-step explanation:
