Answer:
The length of EF = x = 18 cm
Option A is correct.
Step-by-step explanation:
Ware given perimeter of triangle = 97 cm
We need to find length of EF = x = ?
The length of EG = x+7
The length of EF = x
The length of GF = 3x
The formula used is: 
Putting values and finding x i.e length of EF
So, value of x=18 cm
The length of EF = x = 18 cm
Option A is correct.
Answer: x=1.5
Step-by-step explanation:
50% off means half price, so half of 49.98 is 24.99
the necklace now costs 24.99 dollars
Answer:
x≈ 3.2056
Step-by-step explanation:
Set both sides by log. Then, solve for x.
1. 14^(x + 1) = 36
(x + 1)log(14) = log(36)
x + 1 = log(36)/log(14) . . . Divide both sides by log(14)
x = log(36)/log(14) - 1 . . . . Subtract both sides by 1.
x ≈ 0.3579 . . . . . . . . . . . .Use calculator to simplify the expression.
Note that the second problem is similar to the first.
2. 12^(y - 2) = 20
(y - 2)log(12) = log(20)
y - 2 = log(20)/log(12)
y = log(20)/log(12) + 2
y ≈ 3.2056
Answer:
The answer is D.) 27
Step-by-step explanation:
This problem forms a right triangle and with the 90ft wire being the hypotenuse, you subtract 63 from 90 and you get 27.
Hope I helped! :)
