Answer:
x =2
Step-by-step explanation:
The x- intercept is when y = 0
Hence, 5x - 2y = 10
5x - 2(0) = 10
5x = 10
Therefore, x = 2
It would be 110.888888889.
Hope This Helps You!
Good Luck Studying :)
Ratio of height of the man to the length of the shadow = 6:9 = 2:3
Ratio of height of the tree to the length of its shadow = x:25 = 2:3
x/25 = 2/3
x = (25 x 2)/3 = 50/3 = 16.67
Therefore the approximate height of the tree to the nearest foot is 17 feet.
1: KIH because of alternate exterier (or ACF because of verticle angle)
2. x
3. CFG
Answer:
13 , 6.
Step-by-step explanation:
A equation is given to us and we need to find out the value of x . The given equation to us is ,
Cross multiply ,
Squaring both sides ,
Simplify the whole square ,
Add 3 and subtract x on both sides ,
Simplify ,
Split the middle term of the quadratic equation,
Take out common ,
Take out ( x -13 ) as common ,
Equate both factors to 0 ,
<u>Hence</u><u> the</u><u> </u><u>value</u><u> of</u><u> </u><u>x</u><u> is</u><u> </u><u>1</u><u>3</u><u> </u><u>or </u><u>6</u><u> </u><u>.</u>
