Answer:
Hector offers a better deal: $18 for 2 hours.
Step-by-step explanation:
1. You have the following information given in the problem above:
- Ginas offers $28 for 3 hours.
- Hector offers: $18 for 2 hours.
2. Then, you must write the rates:
a) $28 for 3 hours:
dollars per hour.
b) $18 for 2 hours:
dollars per hour.
3. Therefore, the better deal is $18 for 2 hours
Answer:
Hector is providing best deal.
Step-by-step explanation:
Given data:
Gina charges = $28
Time by Gina = 3 hours
Hector charges = $18
Time by Hector = 2 hours
Solution:
Charges per hour by Gina = $28/3
= $9.33
Charges per hours by hector = $18/2
= $9
Hence hector charges low per hour than Gina. So hector provides the best deal.
Explanation:
Now the both instructor provides lesson with different charges with different hour. So if we calculate the charges per hour than the charges per hour Gina is charging more than hector.
Hector is charging $9 for one hour and $27 for 3 hour while Gina is charging $28 for 3 hours.
So the Hector is providing best deal.
Answer:
x = -12
Step-by-step explanation:
To solve an equation, you want to "undo" what has been done to the variable. Here, it has been multiplied by -1 and that result added to 7. In general, you want to "undo" these operations in reverse order.
First, you need to subtract 7 to undo the addition of 7. Of course, anything you do to one side of the equation is also done to the other side:
7 -x -7 = 19 -7
-x = 12 . . . . . . . . simplify
Now, you want to undo the multiplication by -1. Multiplication (or division) by -1 will take care of that:
(-1)(-x) = (-1)(12)
x = -12 . . . . . . . . simplify
The solution is x = -12.
A number x is decreased by 45. The result is then divided by 12. Then 20 is added to this new result to give a final result of five times the difference of 32 and the number x
(This is a little difficult but I've got it)
((x - 45)/12) + 20 = 5(32 - x)
(I made the equation a little more complex than I should have but that equation should still work if you were to solve for x)
Hey there!!
Let's get this step by step
x is decreased by 45 = x - 45
Result is divided by 12 = ( x - 45 ) / 12
Then, 20 is added to the result
[ ( x - 45 ) / 12 ] + 20
Result =
Five times the difference of 32 and x = 5 ( 32 - x )
Hence, the equation
[ ( x - 45 ) / 12 ] + 20 = 5 ( 32 - x )
( x - 195 ) / 12 = 160 - 5x
Multiply 12 on both sides
x - 195 = 12 ( 160 - 5x )
x - 195 = 1920 - 60x
Add 60x on both sides and add 195 on both sides
61x = 2115
divide by 61 on both sides
x = 34.67
x = 34.7
Hence, the required answer is 34.7 this can be rounded to 35
Hope my answer helps!
