Answer:
The AP is 6, 11, 16, 21, 26, 31, 36, 41, 46, 51, 56, 61 ....
Step-by-step explanation:
The nth term = a1 + d(n - 1)
Sum of 5th and 9th terms
= a1 + 4d + a1 + 8d = 72
2a1 + 12d = 72.............(1)
Similarly:
a1 + 6d + a1 + 11d = 97
2a1 + 17d = 97..............(2)
Subtracting equation (1) from equation (2):
5d = 25
d = 5.
and , using equation (1), the first term
a1 = (72 - 12(5)) / 2
= 12/2
= 6.

6a-2(4a-5)=40
How do I solve it
Answer:
Distribute, then combine like terms, subtract 10 from both sides of the equation, simplify, divide both sides of the equation by the same term, and simplify to get your solution.
Step-by-step explanation:
1.) Distribute
6−2(4−5)=40
6−8+10=40
2.) Combine like terms
6a-8a+10=40
-2a+10=40
3.) Subtract 10 from both sides of the equation
-2a+10=40
-2a+10-10=40-10
4.) Simplify
subtract the numbers
-2a+10-10=40-10
-2a=40-10
subtract the numbers
-2a=40-10
-2a=30
-2a=30
5.) Divide both sides of the equation by the same term
-2a=30
[tex]\frac{-2a}{-2} =\frac{30}{-2}[/tex]
6.) Simplify
cancel terms that are in both the numerator or denominator
[tex]\frac{-2a}{-2} =\frac{30}{-2}[/tex]
a=[tex]\frac{30}{-2}[/tex]
Divide the numbers
a=[tex]\frac{30}{-2}[/tex]
a=-15
a=-15
7.) Solution
a=-15

A plane travels at a constant speed. It takes 6 hours to travel 3360 miles.
A - What is the planes speed in miles per hour?
B - At this rate, how many miles can it travel in 10 hours?
Answer:
A-560
B-5600
Step-by-step explanation:
to find the answer for A we need to divide 3360 by 6 which gives us 560.
check: 560 x 6 = 3360
To find the answer for B we need to multiply the answer for A (560) by 10 which gives us 5600
Answer:
A- the question asks the speed and the speed formula is speed=distance÷time. So 3360÷6=560 mph
B- At this rate means at this constant speed which is 560 mph, how many miles can it travel in 10 hours. We will rearrange the speed formula to find the distance. distance=speed×time. So 560×10=5600 miles.

Find the midpoint of the line segment joining the points (-2, -1) and (-8,12).
x¹ = -2 x² = -8
y¹ = -1 y² = 12
Using midpoint formula,
M = ( x¹ + x²/2 ,y¹ + ý²/2)
or,M ={ -2+(-8)/2 , (-1) +12/2}
or, =( -10/2 , 11/2)
:M = ( -5 , 11/2)

A market sells strawberries for $2.00 per pint. Makayla is going to graph this relationship on the coordinate grid below. Total Cost of Berries On a coordinate plane, the x-axis is labeled Pints and the y-axis is labeled Dollars. What point on Makayla’s graph will represent the cost of 4 pints of strawberries? (2, 4) (4, 0) (4, 8) (8, 4)
The point which represents the cost of 4 pints is:
(4,8)
Step-by-step explanation:
We are given that:
A market sells strawberries for $2.00 per pint.
Then, cost of 4 pints= $ 4×2.00
= $8.00
The point on the x coordinate represents number of pints
and the point on the y coordinate represents the cost in dollars
Hence, the point which represents the cost of 4 pints is:
(4,8)

5. Water is flowing from Tower #1 to Tower #2 in the diagram below at a rate of 20 gallons per
minute. Initially, Tower #1 contained 1650 gallons and Tower #2 contained 570 gallons.
(a) How many gallons does each tower contain after 5
minutes? Show your work.
9514 1404 393
Answer:
Tower #1: 1550 gallonsTower #2: 670 gallonsStep-by-step explanation:
After 5 minutes, the amount of water that has flowed is ...
(20 gal/min)(5 min) = 100 gal
That amount has flowed out of Tower #1, so it now has ...
1650 -100 = 1550 . . . gallons in Tower #1
That amount has flowed into Tower #2, so it now has ...
570 +100 = 670 . . . gallons in Tower #2

How much simple interest would $800 earn in 300 days at an interest
rate of 1.71%?
Simple Interest is defined as the interest that would be accumulated on a particular sum of money, loan, or investment kept or obtained from a financial institution.
The simple interest is $11.24
The formula for simple interest is given as:
I = P x R x T
Where
I = Simple Interest
P = Principal = $800
R = Interest rate = 1.71% = 0.0171
T = Time in years = 300 days
Step 1: We have to convert from days to a year365 days = 1 year
300 days = ?
Cross Multiply
300 days x 1 year / 365 days
= 0.822 year
Step 2: We find the Simple InterestI = $800 x 0.0171 x 0.822
I = $11.24
Therefore, the simple interest is $11.24
