Answer:
Step-by-step explanation:
1. Subtract p:
3p +3q -p = 0
2p +3q = 0 . . . . collect terms
2p = -3q . . . . . . subtract 3q
p = -3q/2 . . . . . . divide by the coefficient of p
__
2. Add 7 and divide by the coefficient of b:
4a +7 = 2b
(4a +7)/2 = b
Substitute for a to find the value of b.
(4(3) +7)/2 = b = 19/2
__
3. Divide by the coefficient of r:
r = d/t
__
4. The sum of length and width is half the perimeter:
15 + w = 90/2 = 45
w = 30 . . . . . . . subtract the length; the width is 30 units
It is given in the question that
For th first inequality, we divide both sides by 2, and for second, we subtract 3 to both sides, that is
So the required inequality is
Correct option is B
9/50 = 0.18
0.18*100 = 18%
Answer:
x = 2/3
Step-by-step explanation:
x − 5(x − 1) = x − 2x + 3
−5 (x − 1) = −2x + 3
−5x + 5 = −2x + 3
5 = −2x + 3 + 5x
5 = 3x + 3
5 − 3 = 3x
2 = 3x
2/3 = x
x = 2/3
For the answer to the question above, I'll provide a solution for my answer below.
x^4 - 41x^2 = - 400
<span>=> x^4 - 41x^2 + 400 = 0 </span>
<span>=> x^2 = (1/2) [41 ±√(1681 - 100)] </span>
<span>=> x^2 = (1/2) (41 ± 9) </span>
<span>=> x^2 = 16 or 25
</span>
So, therefore, the answers for your problem are
<span>=> x = ± 4 or ± 5.
I hope my answer helped you. </span>
