Answer:
The equation is 2x + 5.1 = 11.5
Step-by-step explanation:
Given that:
Fiona thinks of a number.
Let,
x be that number.
She doubles the number, therefore
2x
Then she adds 5.1 in the number, thus
2x + 5.1
She gets the answer 11.5, so the equation becomes
2x + 5.1 = 11.5
Hence,
The equation is 2x + 5.1 = 11.5
Answer:
77
Step-by-step explanation:
area triangle=half*base*height
14*11/2
154/2=77
Using the place value chart we can see that the decimal 0.6 is six tenths, so we can write 0.6 as the fraction 
. Notice however that is not in lowest terms so we need to divide the numerator and the denominator by the greatest common factor of 6 and 10 which is 2.

Since a straight line is 180 degrees, if you subtract 180-48 you get 132. Divide this by 2 and get X= 66. Because all angle of a triangle add up to 180, subtract the 90 from the right angle and 66 from x from 180. 180-66-90= 24. This means z=24
