Answer:
The answer is x=-17/3
Step-by-step explanation:
The Steps:
-8 + 5(1 + x) = 2x - 20
-8 + 5 + 5x = 2x - 20
-3 + 5x = 2x - 20
-3 + 3x = -20
3x = -17
x = -17/3
Answer:
t < 0 and t > 140
Step-by-step explanation:
It is given in the question that fluid is not a liquid if its temperature is above 140°C or below 0°C.
So, the inequality that satisfies the temperature at which the fluid is liquid will be given by 140 ≥ t ≥ 0.
Now, the compound inequality for the temperature t when the fluid is not liquid is t < 0 and t > 140. (Answer)
Answer:
(D) xy/(x + y)
Step-by-step explanation:
To find r in terms of x and y
Given,
- two resistors with resistances x and y are connected in parallel
- r is the combined resistance of these two resistors
- the reciprocal of r is equal to the sum of the reciprocals of x and y
Then,
1/r = 1/x + 1/y
1/r = (y + x)/xy
Find the reciprocal of both sides
r = xy/(x + y)
The right answer is option (D) xy/(x + y)

<u>√3</u>
x is the length of the third side
x²+1² = 2² { Pythagorean Theorem}
x²+1 = 4 {Simplify}
x²=3 {Subtract 1 from each side}
x=√3 {Take the square root of each side}
The Length of the third side is √3

Answer:
number 3, if s equals 5mm, then all of the sides on the square would be 5mm, because it is a square. thus making the area 25mm, and the perimeter 20 mm.
