A traveller arrived at 17: 25. The journey took 5 hours and 50 minutes. What time did the traveller start?
Explanation:
"5 hours 50 minutes" is close to "6 hours"
Let's subtract 6 hours from 17:25
It would drop us to 11:25 since 17-6 = 11.
When we subtracted 6 hours, we subtracted 10 extra minutes that we shouldn't have done. To fix this, add 10 minutes on to go from 11:25 to 11:35
Answer:
The traveler started at 11:35
Step-by-step explanation:
The question already gives you the time that the traveler arrived which is 17:25 and how long it took them to get to the desired location which was 5 hours 50 minutes. So what you need to do is subtract the time the traveler arrived to how long it took to get there.
Equation:
17:25 - 5:50
= 11:35

Answer:
Caleb and Devon each bowled for [tex]10[/tex] hours and spent [tex]\$55[/tex].
Step-by-step explanation:
Equations:
Caleb: y = 4x + 15Devon: y = 5x + 5Where:
x = hours spent bowlingy = the total costSystem of equations:
[tex]\begin{cases}y=4x+15\\y=5x+5\end{cases}[/tex]
Solve for x
Step 1: Substitute the second equation into the first.
[tex]\implies 4x+15=5x+5[/tex]
Step 2: Subtract [tex]5x[/tex] from both sides
[tex]\implies 4x-5x+15=5x-5x+5[/tex]
[tex]\implies -x+15=5[/tex]
Step 3: Subtract [tex]15[/tex] from both sides.
[tex]\implies -x+15-15=5-15[/tex]
[tex]\implies -1x=-10[/tex]
Step 4: Divide both sides by [tex]-1[/tex] .
[tex]\implies \dfrac{-1x}{-1}=\dfrac{-10}{-1}[/tex]
[tex]\implies \boxed{x=10}[/tex]
Solve for y
Step 1: Substitute the found [tex]x[/tex] value into one of the system of equations.
[tex]\implies y=4(10)+15[/tex]
Step 2: Multiply and add.
[tex]\implies y=40+15[/tex]
[tex]\implies \boxed{y=55}[/tex]
Therefore, Caleb and Devon each bowled for 10 hours and spent $55.

find x in the following image
Answer:
70°
Step-by-step explanation:
As, the sum of the angles in a straight line is 180°.
<E F C + < E F B = 180
70 + < E F B = 180
< E F B = 180 - 70
< E F B = 110°
Also, we know that the sum of the interior angles in a quadrilateral is 360°
So,
< E A B + < A E F + < E F B + < F B A = 360
90 + 90 + 110 + x = 360
290 + x = 360
x = 360 - 290
x = 70°

Gasoline costs $3.25 per gallon How much does it cost to drive
the 838 miles to Seattle if your car gets 27 miles per galona
Answer:
$100.87 (to the nearest cent)
Step-by-step explanation:
1 gallon = 27 miles
⇒ number of gallons needed to drive 838 miles = 838 ÷ 27 = 31.0370370... gallons
1 gallon = $3.25
⇒ total cost to drive 838 miles = 3.25 x 838/27 = $100.87 (to the nearest cent)

The cat weighs 7 3/4 pounds.The cats weight is 2/3 the weight of the dog.How much does the dog weigh!
Answer:
11.625 pounds
Step-by-step explanation:
x = weight of dog
7 3/4 = 2/3(x)
7 3/4 divided by 2/3 = x
x = 11.625 pounds
Answer:
11 5/8
Step-by-step explanation:
let 'd' = dogs weight
7 3/4 equals 2/3d
change 7 3/4 to an improper fraction: 31/4
to isolate 'd', each side needs to be multiplied by 3/2
31/4 × 3/2 = d
93/8 = d
11 5/8 equals dogs weight

You have $575 to spend on clothes for the school year. You want to by 8 pairs of pants that cost $352.45 including tax and hoodies that will have a 8.7 % sales tax. What is the inequality that represents the amount of money you have to spend?
Answer:
352.45 + 1.087x ≤ 575
Step-by-step explanation:
The most you can spend is $575, so the total you spend must be ≤ 575.
You already have a total for the pants of $352.45.
352.45 + price of hoodies ≤ 575
Let x = total price of the hoodies before tax.
The price of the hoodies with tax is
x + 8.7% of x = x + 0.087x = 1.087x
The inequality is
352.45 + 1.087x ≤ 575

On average the number of drum sets sold in Michigan each year is 101,968, which is eight times the average number of drum sets sold each year in South Dakota. How many drum sets, on average, are sold each year in South Dakota?
Answer:
12,746
Step-by-step explanation:
To find this answer, we need to divide by 8
Since we know that South Dakota sells 8X less than Michigan, we have to use the opposite sign (which in this case is division.)
Now, we use the equation 101,968/8 which gets us an answer of…
12,746!

At Best Buy they have a 60" TV that sells for $1250 and is on sale for 15% off. If the sales tax is 6.5%, what is the final cost?
Answer:
Step-by-step explanation:
The sale price = Initial Cost - 15% of the initial Cost
The sale price = 1250 - 15/100 * 1250
The sale price = 1250 - 187.5
The Sale Price = 1062.5
Now you add on the sales tax
Cost with Sales Tax = 1062.50 + 6.5/100 * 1063
Cost with Sales Tax = 1062.50 + 69.06
Cost with Sales Tax = 1131.56 dollars.

A railroad track rises 10 feet for every 400
feet along the track. What is the measure-
ment of the angle the track forms with the
horizontal?
Answer:
1.43 degrees
Step-by-step explanation:
Think of this as a triangle with an x (horizontal) value of 400 and a y (vertical) value of 10.
Using this train of thought, we can use SOHCAHTOA to find that the tan of some angle (we will use Ф to represent this angle) is equal to the opposite (vertical) value divided by the adjacent (horizontal) value.
As an equation, it looks like this: tan (Ф) = 10/400.
We can use the arctan to find Ф from this equation: arctan (10/400) = Ф
Therefore, Ф is about 1.43 degrees.
