Answer:
Step-by-step explanation:
f+t=40 and 4f+2t=100
4f+2t=120
4f+2t=100
2t=20
t=10
So f=20
Answer:
The explanation of this question is given below in the explanation section
Step-by-step explanation:
The data is given in form of length and width.
Then, we need to convert it into improper fraction.
As you know that, the improper fraction is a fraction where the numerator (top number) is larger than the denominator (bottom number).
So, we converted it into improper fraction i.e.
Improper fraction= lenght/width
Then we reduce the fraction into lowest form and shown in ratio as depicted in attached picture with this solution.
Answer:
y=55 degrees x=125 degrees
Step-by-step explanation:
Answer:15
Step-by-step explanation:
Let d(x) = 2x - 4
Or
y = 2x - 4
We have replace x = y
x = 2y - 4
Now Isolate "y"
x + 4 = 2y
Pass "2" dividing
(x + 4) / 2 = y
y = x/2 + 2
Or
d(x)^-1 = x/2 + 2
