Answer:
Step-by-step explanation:
Given the inequality
0.21x + 0.05(17 - x) > 2.55 where x is the amount of 21% lotion needed
Given
0.21x + 0.05(17 - x) > 2.55
Open the parenthesis
0.21x + 0.85-0.05x > 2.55
Collect like terms
0.21x-0.05x+0.85>2.55
0.16x+0.85>2.55
0.16x>2.55-0.85
0.16x > 1.7
x > 1.7/0.16
x > 10.625
Hence she will need 21% lotion approximately greater than 10 ounces
Answer:
x > -6
Step-by-step explanation:
Here in this question, we have to solve for x from the given inequality
-6 > -30- 4x.
We can solve the inequality equation by using the properties of inequality.
We have, -6 > -30 -4x
⇒ -6+30 > -4x
{The summation and subtraction rules of the inequality equation is similar to that of ordinary equations}
⇒24 > -4x
Dividing both sides by -1, we get,
⇒-24 < 4x
{In case of division of both the sides of an inequality by a negative number, the inequality sign changes from > to < and vice-versa}
⇒4x > -24
Dividing both the sides by 4, we get
⇒ x > -6 {There is same rule as equality equation for division both sides by a positive number} (Answer)

Answer:
2x - 1
Step-by-step explanation:
Since logarithm has the following property:
If 
and 
,
Then 
and 
Therefore,
There is only one number that is equal to the absolute value of 15.
That number is 15.
But wait !
There are two different numbers WHOSE ABSOLUTE VALUES
are both 15.
Those numbers are 15 and -15 .
