To find out 1 pound: 6.75 / 3 = 2.25
To find out 5 pounds: 2.25 x 5 = 11.25
Answer: Peters age is 25 years old.
The two equations that can be written given the information are:
h = x/5 + 7 and 4h = 2x - 2
When x = Peter's age and h = Phil's age.
If we use substitution, we can come up with the equation:
4(x/5 + 7)= 2x - 2
4x/5 + 28 = 2x - 2
4x + 140 = 10x - 10
150 = 6x
25 = x
Solving this for x, we give us that Peter's age is 25.
Answer:
h > 5
h < 0
Step-by-step explanation:
We suppose that a "Special Solution" inequality is one that is technically incorrect, but is written using a compact "shorthand" form.
As written, the inequality claims that 17 < 2, which is false. There can be no value of the variable that will make this true. We presume the intended meaning is ...
17 < 3h +2 <u>or</u> 3h +2 < 2
<h3>Special solution</h3>
Subtracting 2 from the inequality gives ...
15 < 3h < 0
Dividing by 3 gives ...
5 < h < 0
There is no value of h that is both greater than 5 and less than 0, so we presume this means the OR (union) of the solution sets ...
h > 5
h < 0
Answer:
20 square units
Step-by-step explanation:
Area = 5 x 8 x 1/2
Area = 40 x 1/2
Area = 20
