Answer:
x=-1
Step-by-step explanation:
The first step is to expand everything in parentheses.
-2(3x-4)=4(x+3)+6
-6x+8=4x+12+6
Now, combine like terms.
10x=-10
Finally, divide both sides by 10 to isolate x.
x=-1

Hawaii (12° F)

Enter the difference, in degrees, between the record low temperatures
Hawaii and South Dakota.
Answers
Final answer:
The difference in degrees between the record-low temperatures of Hawaii and South Dakota is 70°F.
Explanation:
The difference in degrees between the record-low temperatures of Hawaii and South Dakota can be found by subtracting the temperature of South Dakota from the temperature of Hawaii.
Hawaii has a record low temperature of 12°F and South Dakota has a record low temperature of -58°F.
Therefore, the difference in degrees between the two record-low temperatures is:
(12°F) - (-58°F)
= 12°F + 58°F
= 70°F.

Construct a linear equation for the table. What is the slope of the line
Answers
We have points (-3, 4), (-1, 2), (4, -3) and (6,-5)
Let's verify it's a line by calculating the slopes between successive points.
Slope is change in y over change in x.
(2 - 4)/(-1 - -3) = -2/2 = -1
(-3 - 2)/(4 - -1) = -5/5 = -1
(-5 - -3)/(6 - 4) = -2/2 =-1
Yup. We have a line of slope -1 through point (-1, 2)
y - 2 = -1(x - -1)
y = -x - 1 + 2
y = -x + 1
That's the linear equation for the table.
Answer: Linear equation: y = -x + 1 slope = -1
Crystal owes $8,950 on her Electronics Boutique credit card with a 18.4% interest rate. She owes $6,390 on her Miscellaneous Goods credit cards which has a 22.9% interest rate. What is the total monthly payment needed to pay off both cards in three years, assuming she makes fixed payments and does not charge any more purchases with the card?
Answers
Final answer:
The total monthly payment needed to pay off both cards in three years, assuming fixed payments and no further charges, is $550.78.
Explanation:
Calculating the Total Monthly Payment
To calculate the total monthly payment needed to pay off both cards in three years, we need to find the monthly payment for each card and add them together.
Calculating the Monthly Payment for Electronics Boutique Credit Card
Step 1: Calculate the monthly interest rate by dividing the annual interest rate by 12. For the Electronics Boutique card, the monthly interest rate is 18.4% / 12 = 1.53%.
Step 2: Use the formula for calculating the monthly payment on a loan:
Monthly Payment = (Principal * Monthly Interest Rate) / (1 - (1 + Monthly Interest Rate)^(-Number of Payments))
For the Electronics Boutique card, the principal is $8,950 and the number of payments is 3 years * 12 months per year = 36 months.
Plugging the values into the formula, the monthly payment for the Electronics Boutique card is $320.84 (rounded to the nearest cent).
Calculating the Monthly Payment for Miscellaneous Goods Credit Card
Following the same steps as above, the monthly payment for the Miscellaneous Goods credit card is $229.94 (rounded to the nearest cent).
Calculating the Total Monthly Payment
To get the total monthly payment, we add the monthly payments for both cards: $320.84 + $229.94 = $550.78 (rounded to the nearest cent).

Rosa is converting a unit of measure in one system to a unit of measure in another system. 1,760 yd1 mi⋅0.914 m1 yd⋅1 km1,000 m Which statement about Rosa's calculations is true?
Rosa is finding the number of kilometers in a mile.
Rosa is finding the number of meters in a mile.
Rosa is finding the number of miles in a kilometer.
Rosa is finding the number of yards in a kilometer.
Answers
Answer: Rosa is finding the number of kilometers in a mile.
Step-by-step explanation:
According to the given information, we have:
1,760 yd=1 mi
0.914 m=1 yd
1 km=1,000 m
So, as we can see, Rosa wants to convert miles to yards, then yards to meters and finally meters to kilometers:
[tex](1 mi\frac{1,760 yd}{1 mi})( \frac{0.914 m}{1 yd})( \frac{1 km}{1,000 m})=1.608 km[/tex]
Then:
[tex]1 mi=1.608 km[/tex] This is the number of kilometers in a mile.

Find the equation using the graph and table of values.
Answers
Answer:
[tex]y=-1x+1[/tex]
Step-by-step explanation:
To find the equation, you have to know the equation 'format' which is [tex]y=mx+b[/tex]
mx is the slope
b is the y-intercept
The slope is -1 because it goes down 1 and right 1 [tex]\frac{rise}{run}[/tex]
The y-intercept is 1 because that is where the line touches the y-axis.
So, if we plug it in, it will look like:
y = -1x + 1 which can also be written as y = -x + 1
The common difference ,d in an arithmetic sequence whose fourth term is 16 and whose seventh therm is 31
Answers
Answer: d=5
Step-by-step explanation:
Arithmetic progression
An=a1+d(n-1)
An= nth term
A1= first term
D= common difference
N= nth position
We are given the 4th and 7th terms
For 4th term,n=4
A4=a1+d(4-1)
A4= 16
16= a1+d(4-1)
16= a1+3d........equation 1
For the 7th term,n=7
A7=a1+d(7-1)
A7= 31
31=a1+6d......equation 2
Bring them together
16=a1+3d
31=a1+6d
Subtract equation 1 from 2
So we have
15=3d
D=15/3
D=5
Therefore, the common difference is 5
The owner of an office building is expanding the length and width of a parking lot by the same amount. The lot currently
measures 120 ft by 80 ft, and the expansion will increase its area by 4.400 ft? By how many feet should the length of the
parking lot be increased?
Answers
Answer:
The length of the parking lot should be increased by 20 feet.
Step-by-step explanation:
First, you find the product of 120 and 80, you get 9600.
Next, add 4400 to it. You get 1400
Finally what would you add to both 120 and 80 to get 14000? 20 to get 140*100.

The number 6.82245628434 rounded to 5 decimal places is 6.82245.
Explanation:To round the number 6.82245628434 to 5 decimal places, you should consider the 6th digit beyond the decimal point. In this case, the 6th digit is number 5, and the 5th digit is 2 that is even. Because the digit following the decimal place you are rounding to (5th place, the digit is 2) is exactly 5 and preceding digit is even, you don't round up the preceding digit.

A windshield wiper blade turns through an angle of 135°. The bottom of the blade traces an arc with a 5-inch radius. The top of the blade traces an arc with a 22-inch radius. To the nearest inch, how much longer is the top arc than the bottom arc? Round to the nearest whole number.
Answers
The upper arc is longer than the lower arc by inches.
Step-by-step explanation:
Since both the arcs are made by the same wiper blade, hence the angle of the arc would be the same.
The radius of upper arc= 22 inch
The radius of the lower arc= 5 inch
Angle made by the arc= 135°
We know that length of the arc= (angle made/360)*2πr
Where r is the radius of the arc
The difference in the arc length has been due to the difference in radius of the arcs.
Hence, the difference in the radius would be equal to the difference in arc length.
Difference in wiper radius= 22-5= 17 inch
Putting the values together
arc length= (135/360)*2*3.14*17
arc length= 40.035
The difference in arc length=40 inches (rounded off to the nearest whole number)
