Answer:
21 is the answer for 18x +3
Step-by-step explanation:
18x + 3
x=3+18
x=21
The tree is 25 feet tall. Given the height of the stick and the shadow it cast, the angle formed by the sun and the stick's height can be obtained by taking the Inverse Tangent of 3/5. This is equal to 30.93. This angle is equal to the angle formed by the sun and the tree's height. Using the tangent formula, Tan (30.93)=tree's shadow (15 ft)/ height of the tree, giving the answer 25 feet.
Step-by-step explanation:
since all angles add up to 180:
(8x-1)+(3x+4)+(3x+9)=180
add like terms:
14x+12=180
x=12
Hope that helps :)
Assume x books are produced.
Then let 53808 + 12.5x = 17328 + 20.5x
Solve for x:
x = 4560
42% of 100 is 42 so 42% of is half of the first answer, therefore the answer is 21.
