6x + 2(7x – 4) = 92 I T
Answer:
x = 5
Step-by-step explanation:
6x + 2(7x – 4) = 92
simplify:
6x + 14x - 8 = 92
20x = 100
x = 5
Answer:
6x+2(7x−4)=92
Step 1: Simplify both sides of the equation.
6x+2(7x−4)=92
6x+(2)(7x)+(2)(−4)=92(Distribute)
6x+14x+−8=92
(6x+14x)+(−8)=92(Combine Like Terms)
20x+−8=92
20x−8=92
Step 2: Add 8 to both sides.
20x−8+8=92+8
20x=100
Step 3: Divide both sides by 20.
100
20
x=5

A long-distance delivery truck averages 8 miles per gallon when the truck is full. The
miles per gallon improves by 20% when the truck is empty. If the truck travels 160 miles
full to deliver its goods, and then travels back 160 miles empty, approximately how many
gallons will the truck use in all?
The gas used by truck is 36.66 mpg.
What is linear equation?When graphed, a linear equation always produces a straight line because it is an algebraic equation with each term having an exponent of 1. It is referred to as a "linear equation" for this reason.
One-variable linear equations and two-variable linear equations exist.
Given
A long-distance delivery truck averages 8 miles per gallon when the truck is full.
The miles per gallon improve by 20% when the truck is empty.
The distance delivery truck averages 8 miles per gallon when full, and the amount of gasoline used (g) is expressed in terms of the number of miles driven ([tex]m_{f}[/tex]).
When the truck is full, the amount of gasoline is shown as,
[tex]m_{f}[/tex] = d/8
given distance is 160 miles
[tex]m_{f}[/tex] = 160/8 = 20 mpg
Then,
The miles per gallon improve by 20% when the truck is empty.
The number of miles driven when empty is represented as,
[tex]m_{e}[/tex] = d/(8 + 1.6)
[tex]m_{e}[/tex] = d/9.6
[tex]m_{e}[/tex] = 160/9.6
[tex]m_{e}[/tex] = 16.66 mpg
total gasoline required = [tex]m_{e}[/tex] + [tex]m_{f}[/tex] = 20 + 16.66 = 36.66 mpg
Hence the total gas used is 36.66 mpg.

Steven warms a cup of a coffee to a temperature of 195°F and then leaves it to cool in a room that is 75°F. This equation represents the
temperature, T, of the coffee in the cup after x minutes.
T = 75 + 120e-0.051
After how many minutes will the temperature of the coffee be approximately 141°F?
Answer:
12 minutes
Step-by-step explanation:
First substitute 141°F for T in the given equation.
Then isolate the exponential term.
Now rewrite the equation as a natural log, and solve for x.
After 12 minutes will the temperature of the coffee be approximately 141°F.
What is temperature?Temperature is the degree of hotness or coldness expressed in terms of any of numerous scales, such as Fahrenheit and Celsius. Temperature suggests the route wherein heat strength will spontaneously flow—i.e., from a warmer body (one at a better temperature) to a less warm frame (one at a lower temperature).
diploma measures of temperature are typically expressed with the ° temperature scale: The sample became heated to 80 °C.
Substitute the 141°F in the equation
⇒T = 75 + 120e-0.051
⇒ 141 = 75 + 120x - 0.051
⇒ 120x = 141 -75 + 0.051
⇒120x = 66.051

Let's write -9 where we see A:
-9x² + bx + c = 0Let's write 0 where we see B:
-9x² + 0.x + c = 0(Since B = 0, when it is multiplied by x, it becomes 0 again)
-9x² + c = 0Let's write -2 where we see C:
-9x² + -2 = 0Now we can move on to solving our equation:)
Let's put the known and the unknown on different sides:
(-2 goes to the opposite side positively)

If you are being paid $55 for a days work which is an 8 hour shift how much would you get paid if you only worked 6 hours?
Answer:
You would get paid $41.25 if you only worked 6 hours.
Step-by-step explanation:
In order to find the answer, first you have to find the amount you are paid per hour by dividing the amount paid per day by 8 hours:
$55/8=$6.875
Then, you have to multiply the amount per hour for 6 to determine the amount you would get paid if you only worked 6 hours:
$6.875*6=$41.25
According to this, the answer is that you would get paid $41.25 if you only worked 6 hours.

You have a balance of $4,600 on your credit card. The interest rate is 12% (1% per month). The late payment fee is $40.
You miss a payment. What are your fees plus interest for the month?
Answer:
$86
Step-by-step explanation:
first you gotta find the interest
4,600 * 1% = 46
so the interest is $46
then you add the interest and late fees together to get the payment for the month
46 + 40 = $86
your total cost is $86
The fess plus interest of the month will be $86 after missing a payment.
Given:
Balance = $4600
Interest rate = 0.01
Step 1: Calculate the interest for the month.
Interest for the month = Balance × Monthly Interest Rate
Substituting the value back to the formula
Interest for the month= $4,600 × 0.01
= $46
Step 2: Add the late payment fee.
Late payment fee = $40
Step 3: Total fees plus interest for the month.
Total = Interest for the month + Late payment fee
Total = $46 + $40
Total = $86
So, fees plus interest for the month when you miss a payment amount to $86.
