Answer:
an infinite number
Step-by-step explanation:
The left side of the equation is a restatement of the right side of the equation. It is true for all values of x. There are an infinite number of solutions.
Ratio and proportion
height :legnth of shadow=56:49 (man's shadow)
we assume the ratio is the same for the tower thing (obelisk)
so
56:49=x:28
conver tto fraction
56/49=x/28
times both sides by 28
1568/49=x
32=x
answer is 32ft
Answer:
8
Step-by-step explanation:
378-36-270=9x
72=9x
72÷9=9x÷9
8=x
X=8
1.No error , he divided by 16 in the 2 sides .
2.no error ,he made sure that 16/16 is one while d/16 remains
3.no error , he square rooted both sides
4.error, as the root gives one positive value and one negative value not only a positive value ,the answer should have been t=+-(d/4)
5.error,he disturbed the whole equation by rooting d only he should have rooted both sides
The area of a Square is 144 because 12x12 is 144 and if both sides are 12 then that equals 144.
Hope this helps!
