Answer:

530

Step-by-step explanation:

19 + (n-1)26-19 = an

19 + 7n - 7 = an

12 + 7n = an

given n = 74

12 + 7(74) = an

530.

Answer:

a.) Total amount spent on gasoline and oil = $ ( 3.95g + 4.45c )

b.) Total amount spent by Maria = $ 74.02

Step-by-step explanation:

As given,

Cost of gasoline = $ 3.95 gallon

Cost of oil per can = $ 4.45

Also given,

Maria bought g gallons of gasoline and c cans of oil

⇒ Total cost of g gallons of gasoline = g×3.95 = $3.95g

   Total cost of c cans of oil  = c×4.45 = $4.45c

Now,

a.)

Total amount spent on gasoline and oil = $ ( 3.95g + 4.45c )

b.)

As given ,

Maria buy gasoline , g = 8.6 gallons

Maria buy cans of oil , c = 6

So,

Total amount spent = $ 3.95(8.6) + 4.45(9)

                                = $ 33.97 + 40.05 = $ 74.02

⇒Total amount spent by Maria = $ 74.02

Answer:

[tex]y-(9)=(-8)(x-8)\\[/tex]

Step-by-step explanation:

[tex](x_1, y_1) = (8, 9)\\(x_2, y_2) = (9,1)\\[/tex]

Step one: Find the slope (m)

[tex]slope=m=\frac{rise}{run} =\frac{y_2-y_1}{x_2-x_1} = \frac{1-9}{9-8} =\frac{-8}{1} =-8[/tex]

Step two: Plug your known values into the point-slope equation

[tex]m=-8\\y_1=9\\x_1=8\\[/tex]

Point-slope form is [tex]y-y_1=m(x-x_1)[/tex]

[tex]y-(9)=(-8)(x-8)\\[/tex]

If you want to convert point-slope form to general form, isolate for y.

[tex]y-9=-8x+64\\y=-8x+73[/tex]

Answer:

18/3 or 6

Step-by-step explanation

9/1 and 9 is the same thing and because we are multiply fractions you add the 9/1 so it makes 9/1 x 2/3.

9/1 x 2/3 = 18/3

18/3 = 6

Hope it makes sense!  

Answer:

Ans: 5.94

Step-by-step explanation:

according to bodmas,

we should solve division first then

multiply it with 9.

So,

= 9 × 2/3

= 9 × 0.66

= 5.94 ~ 6(approx)

Answer:

16 4/7

Step-by-step explanation:

First, you cant subtract 3/7 from 6/7 so take 1 from 19, which turns it to 18. And add that one to 3/7 to get 10/7, or just add 7 to your numerator. So now you have 18 10/7 - 12 6/7. so subtract 18 - 12 to get 6, and the subtract 10/7 - 6/7 to get 4/7. You dont actually have to subtract the denominator just the numerators, because the denominatos are the same so you leave them just the way they are. I hope this helps :)

Answer:

440h is the expression. When 3 1/4 is evaluated you get 1,430 calories burned.

Step-by-step explanation:

440 represents the number of calories she burns per hour. To represent the hour, we place a variable which is h. After we write the expression, we substitute 3 1/4 for h. When I did this, I turned 3 1/4 into an improper fraction, which was 13/4, and then divided 13 by 4 to get 3.25

Multiple 3.25 by 440 to get an answer of 1,430 calories burned.

Hope this helps :)

Answer:

the least common denominator is 12

Answer:

The Answer is 11r + y

Step-by-step explanation:

If you combine 8r and 3r you can make 11r. From there, you just make negatives, positives and you have 11r + y! :)  

Answer:

x = -2

And, x = 7 ÷ 2

Step-by-step explanation:

Given that

y = 2x^2

y = 3x + 14

Now equate these two above equations

2x^2 = 3x + 14

2x^2 - 3x - 14

2x^2 -7x + 4x - 14

x(2x - 7) + 2(2x - 7)

(x + 2) (2x - 7)

So it can be x = -2

And, x = 7 ÷ 2

Answer:

40 t-shirts

Step-by-step explanation:

Answer:

factoring out the 1/2 (that is the coefficient of the variable) would require you to divide the equation by one half, which is the same as multiplying by two. After doing this, the answer can be expressed as:

1/2 (d+12)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Factor out a 1/2

[tex]\frac{1}{2}(d+12)[/tex]

Redistribute if you want to check your work

[tex]\frac{d}{2}+\frac{12}{2} =\frac{1}{2}d+6[/tex]

Answer:

6

Step-by-step explanation:

Richard gets 7 more sweets than Gavin which would probably make Richard have the most so in total he should have around 8 whilst Gavin has 1 so right now we have 4:1:?. Basing off the fact that Richard would have the most sweets Henry would have to have 6 sweets to be able to divide half of it for 3. 4:1:3

Divide tip by portion of bill:

1.80/0.20 = 9.00

The total bill before the tip was $9.00

Divide total bill by 1+ sales tax rate:

9.00 / 1.08 = 8.33

The bill before tax was $8.33

Answer:

10 - 9 + 12x = 4x - 9 + 8x

x - 6 = 6 - x
