Answer:
1/2, -1/8, 1/32
Step-by-step explanation:



Step-by-step explanation:
- 4x+5= 20
- 4x=20-5
- 4x= 15
- x= 15/4
therefore the answer is option
b) X= 15/4

Answer:
infinite solutions along the line y = 2x+1
Step-by-step explanation:
3y – 6x = 3
y = 2x + 1
Replace y in the first equation with the second equation
3 ( 2x+1) -6x =3
6x +3 -6x = 3
3=3
This is always true so there are infinite solutions along the line y = 2x+1
Answer: $66.7
Step-by-step explanation:
Answer:The equation for inverse proportion is calculated as xy=k.
When 20 people attend the picnic, the cost for each person was $50, then k will be= 20 × 50 = 1000
Recall that k = xy
For the second aspect of the question, x= 15, k= 1000.
k= xy
y = k/x
= 1000/15
= 66.7
If 15 people attend the picnic instead, the cost per person will be $66.7
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)
