The equation is
. We can rewrite the equation as:
.
Our next step here is to take the square root of both sides, remembering that
.
Thus, we have
. Our final step is solving the absolute value equation, which yields:
or
.
Solution set: {
}
Not sure if the equation is
or
On the other side of the equation, we'd get
Then
- If it's the second one instead, you can use the same strategy as above:
(Note that this step assume )
Then we get
Answer:
3.75 liters a day
Step-by-step explanation:
Answer:
Solution set {x|x<8}
Step-by-step explanation:
0.35x - 4.8<5.2- 0.9x
0.35x+0.9x<5.2+4.8
1.25x<10
x<10/1.25
x<8
Solution set {x|x<8}
Answer:
True
Step-by-step explanation:
Volume is calculated by length x width x height, so you just multiply the values. 6 x 7 x 9 = 378 cm^3.
