Speed is d/t or distance/time so 70/3 = 23.33 mph
Answer:
For this case, we have the following equation (according to the comments):
First, we factor the quadratic expression in the denominator:
Then, we multiply both sides of the equation by (a-2) (a + 2):
Later, canceling similar terms we have:
We do distributive property on the left side of the equation:
By grouping variables and constant terms we have:
Rewriting we have:
Finally, by clearing "a" we have:
Note: the value of a is a extraneous solution because it makes the denominator of the original equation equal to zero.
Answer:
the student correct, but the value of a= -2 is an extraneous solution
Answer:
x = 15
Step-by-step explanation:
by solving;
- 4x + 8x +14 -14 = 180
- 12x = 180
- x = 180 / 12
- x = 15
