Answer:
The answer is x = -5
Step-by-step explanation:
In order to find the answer, we first have to put the equation into numerical terms.
14x - 8 = 20x + 22
Now we can solve this using the order of operations.
14x - 8 = 20x + 22 -----> subtract 20 x from both sides
-6x - 8 = 22 ----> add 8 to both sides
-6x = 30 -----> divide both sides by -6
x = -5
Answer:
the first option is correct
since value of a will be found through division.
Answer:
75
Step-by-step explanation:
divide the interest by the amounts of years
Let us say that h is the height of the guardrail.
Therefore the inequality equation that we can generate from this scenario is:
| h – 106 | = ± 7
There are two ways to solve this, either the equation is
positive or negative.
When the equation is positive, therefore:
| h – 106 | = 7
h = 7 + 106 = 113 cm
When the equation is negative, therefore:
| h – 106 | = - 7
h = -7 + 106 = 99 cm
So the height must be 99 cm to 113 cm
