The solution of expression 4m + 9 + 5m - 12 = 42 by combining like terms is,
⇒ c = 6
Given that,
A mathematical expression is,
⇒ 7c + 12 = -4c + 78
Now, simplify the expression by combining like terms and solve for m as,
⇒ 7c + 12 = -4c + 78
Combine like terms by adding 4c and subtracting 12 on both sides,
⇒ 7c + 4c = 78 - 12
⇒ 11c = 66
Divide by 11 on both sides,
⇒ c = 66/11
⇒ c = 6
So, the solution is,
⇒ c = 6

E. lower maintenance costs
Answer:
B
Step-by-step explanation:
Remark
The question is an application of the Tangent Function.
Tan(63) = Opposite / Adjacent
Givens
Opposite side = height of the tree = 50 feet.
Adjacent side = shadow length which we have to solve for.
Solution
Tan(63) = opposite/ Adjacent Add a 1 on the left so you have a proportion.
Tan(63)/ 1 = 60 / adjacent Cross multiply
Adjacent * Tan(63) = 1 * 60
Adjacent = 60 / tan(63)
Adjacent = 60 / 1.963
Adjacent = 30.57 feet.
b. (20/14)
c. (14/20)
d. (10/7)
when putting ratios, fractions, expressions, etc into lowest terms you take out the gcf.
in this case the gcf of both 20 and 14 is 2.
20/2:14/2 = 10:7
the answer is d
Answer=12%
The lower the percent, the more unlikely that the event will happen. Since 12% is the lowest percent, it is also the most unlikely of the options.
