Add he fractions first, 1/9 + 4/9 which is 5/9. Now add the whole numbers which are 2 and 7, and you get 9. Your fraction will be 9 5/9 and this number cannot be simplified anymore.
Answer:
Step-by-step explanation:
9x+
=x-13
9x*3+1/3=x-13
27x+1/3=x-13
27x+1=3(x-13)
27x+1=3x-39
27x-3x=-39-1
24x=-40
x=-5/3
x=-5/3
Answer:
54 cm
Step-by-step explanation:
Measures are proportional on a scale drawing:
drawing measure : actual measure = 6 cm : 3 m = x : 27 m
The value on the right of the x ratio, 27, is 9 times 3, so the value of x will be 9 times 6 cm.
54 cm on the blueprint represents an actual distance of 27 meters.
Answer:
f^-1(x) = x +6
Step-by-step explanation:
To find the inverse of the function
y = f(x)
solve the equation
x = f(y)
for y.
Here, you want ...
x = f(y)
x = (y -6)
x +6 = y . . . . . . add 6 to both sides
First, distribute the 3 to the parentheses.
2x + 16 = 3x - 27
Add 27 to the left.
2x + 43 = 3x
Subtract 2x to the right.
43 = x
