Answer:
8.26772
Step-by-step explanation:
1 centimeter is equaled to 0.393701 in inches so multiply it by 21
For this case what we have to take into account is the following variable:
x = represent the unknown number
We now write the following inequality:
"four times the sum of number and 15 is at least 20"
4 (x + 15)> = 20
We clear the value of x:
(x + 15)> = 20/4
(x + 15)> = 5
x> = 5 - 15
x> = - 10
The solution set is:
[-10, inf)
Answer:
all possible values for X are:
[-10, inf)
Answer:
$65.35
Step-by-step explanation:
- First you have to divide 5.4% by 100
- Take 5.4/100 and multiply it by 62
- Take the number you get from step 2 and add it to 62! (:
Answer:
(x + 2)²(x - 3)² = 0
Step-by-step explanation:
Since we have a degree of 2 and double of the same roots, we know that each root would have a multiplicity of 2. Therefore, our answer is(x + 2)²(x - 3)² = 0
Answer:
Step-by-step explanation:
Multiply both sides of the equation by 5.
5 · 
· 
5 · 4
Simplify both sides of the equation.
Subtract 10 from both sides of the equation.
Divide each term by 2 and simplify.

Substitute x for 6
Multiply 3 · 6
Add 18 + 9
Divide 
÷ 27
9 = 9
