Answer:
What is the question? You only gave us the information heh
Step-by-step explanation:
Answer:
x = -5 or x = -4/3
Step-by-step explanation:
First possibility.
|2x − 1| = |4x + 9|
2x - 1 = 4x + 9
2x - 4x = 9 + 1
-2x = 10
x = 10/-2
x = -5
Second possibility.
2x - 1 = - (4x+9)
2x - 1 = -4x - 9
2x + 4x = -9 + 1
6x = -8
x = -8/6
x = -4/3
Answer:
Step-by-step explanation:
Given, water is filling the bathtub at 60 liters per minute
Thus it follows that after minutes, there will be 60 times liters of water
So there will be liters of water in the bathtub after minutes.
Answer:
Measure of and in degrees.
Step-by-step explanation:
Given:
A parallelogram where angles A and D measures same also, C and B measures same.
According to the question:
Measure of angle C is twice the measure of angle A.
Let the measure of angle A be "x" degree.
Accordingly :
Measure of each angle C and B = "2x"
Measure of each angle A and D ="x"
Note:
The sum of the measures of the angles of a parallelogram is 360°.

⇒
⇒
So,
Measure of angle A and D be 60 degrees each.
Measure of angle B and C is 120 degrees each.
Answer:
5 generations
Step-by-step explanation:
Data provided in the question:
Number of bacteria at the beginning of a time interval
, B = 4
Number of bacteria at the end of the time interval, b = 128
Now,
The relation between the bacteria at the beginning, bacteria at the end and the number of generations (n) is given as:
b = B × 2ⁿ
Therefore,
on substituting the respective values, we get
128 = 4 × 2ⁿ
or
2ⁿ = 32
or
2ⁿ = 2⁵
or
n = 5
hence,
5 generations
