Answer:
a:b = 11:3 and a:b:c = 11:3:2
Step-by-step explanation:
a:b is equal than write a/b. So a/b=11/3 it means a:b = 11:3
b:c is then b/c = 2
For a:b:c the ratio must be maintained. Ratio is equals reasons or divides. We already know a:b is 11:3. What about a:c?
3a=11b then a=11/3 b, b=2c then c=1/2 b hence a/c =22/3 if we pay attention this reason is 2*11/3 so a:b:c is 11:3:2
Since we divided by a negative 2 on both sides the sign switches and the answer is { a. x > -1 }
Answer:
The answer is 75 degrees.
Step-by-step explanation:
The explanation is that the the supplementary angle to 80 is 100 since a straight line has an angle of 180, now the 100 degree angle is congruent to the angle x + 25 which means that x + 25 is equal to 100 so x is 75
To find the final term to compete the square you need to divide the 'x' term by 2 then square it
- equivalent equation
