Answer:
C.) 2 1/2
Step-by-step explanation:
X + 2 1/4 = 4 3/4
Change the fractions to improper fractions .
We have
X + 9/4 = 19/4
Subtract 9/4 from both sides
X + 9/4 - 9/4 = 19/4 - 9/4
X = 19/4 - 9/4
Look for the LCM of the denominators.
The LCM is 4
Divide the LCM by the denominators and multiply the results by the numerators, the lcm becomes the denominator of the results.
That’s
X = 19 - 9 /4
= 10/4
Divide both numerator and denominator by 2
= 5/2
= 2 1/2

Answer:
2232.48 meters
Step-by-step explanation:
From the diagram:
Radius of semicircle = 74
Length of straightway on each side = 1000
The length of school track:
Straightway on each side = 2 * 1000 m = 2000m
Length of semicircle = πr/2
Length of both semicircle = 2 * 3.142 * 74 /2 = 232.47785
Total Length = ( 2000 + 232.47785) = 2232.48 meters
Hope this helps!
Answer:
Step-by-step explanation:
<u>Given:</u>
- f(x) = 7x² - 3
- g(x) =
<u>To find f(g(x)), substitute x in f(x) with the value of g(x):</u>
- f(g(x)) =
= 7(2x³) - 3 = 14x³ - 3
This represents the amount of money she earns every hour, where x is the number of hours.
Answer:
21m
Step-by-step explanation:
So for the rectangle, do 5*6, and you will get the area of the whole backyard. Then to get the area of the grass, you do 3*3 to get 9.
Finally, to get the cement, you subtract the area of the grass from the area of the whole backyard so 30-9 to get 21.
5*6=30
3*3=9
30-9+21
