A)
1) v = 36
2) a = 2
B)
1) c = 22
2) I don’t know
C)
1) P = 2
2) b = 3
I’m not 100% sure these are right but I’m pretty sure :)
5 (m - 3) = 7m - 17
Eliminate
parentheses: 5m - 15 = 7m - 17
Subtract 5m
from each side: - 15 = 2m - 17
Add 17
to each side: 2 = 2m
Divide
each side
by 2 : 1 = m
No more solutions.
Only one.
First, let's create an equation for this problem.
($70 × 4) + $40
Now, all you would have to do is solve it using the order of operation (PEMDAS).
($70 × 4) + $40 = $280 + $40
$280 + $40 = $320
The plumber charged $320.
I hope this helps!
Answer: (x-2) = (x+11)
------- -------
3 4
Step-by-step explanation:
First part is x-2 divided by on third. So the x-2 acts a the 1 so you put x-2 over 3. And you get:
(x-2)
--------
3
For the other side of the equation it is x +11 divide by 1/4. So the x+11 will act a the 1 in the fraction. And you will get:
(x+11)
--------
4
(x - 2)² + 1 = 0
(x - 2)(x - 2) + 1 = 0
x(x - 2) - 2(x - 2) + 1 = 0
x(x) - x(2) - 2(x) + 2(2) + 1 = 0
x² - 2x - 2x + 4 + 1 = 0
x² - 4x + 4 + 1 = 0
x² - 4x + 5 = 0
x = <u>-(-4) ± √((-4)² - 4(1)(5))</u>
2(1)
x = <u>4 ± √(16 - 20)</u>
2
x = <u>4 ± √(-4)
</u> 2<u>
</u> x = <u>4 ± 2i</u><u>
</u> 2<u>
</u> x = 2 ± i
x = 2 + i U x = 2 - i
The solution set is {2 ± i}.
