Add like terms first,
2m = 48 + 16
2m = 64
m = 64/2
m = 32
Answer:
17 feets 3 inches
Step-by-step explanation:
Given :
Converting the parameters to inches only:
Recall:
1 feets = 12 inches
Man's height : 5 feets 9 inches = (12 *5) + 9 = 69 inches
Man's shadow : 3 feets 6 inches = (12 * 3) + 6 = 42 inches
Tree's shadow : 10 feets 6 inches = (12 * 10) + 6 = 126 inches
(Tree's height / tree's shadow) = (man's height / man's shadow)
Let tree's height = x
x / 126 = 69 / 42
Solve for x
42x = 126 * 69
42x = 8694
x = 8694 / 42
x = 207 inches
207 / 12 = 17 feets 3 inches
Answer:
-13/6 or (in mixed number form) -2 1/6
Step-by-step explanation:
Rewriting our equation with parts separated
=10+512−12−712
Solving the whole number parts
10−12=−2
Solving the fraction parts
512−712=−212
Reducing the fraction part, 2/12,
−212=−16
Combining the whole and fraction parts
−2−16=−216
Another way to do it:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
125/12−151/12
Applying the fractions formula for subtraction,
=(125×12)−(151×12) / 12×12
=1500 − 1812/ 144
=−312/144
Simplifying -312/144, the answer is
=−2 1/6
