Answer:

1) El helado costó $135,65.

2) a) Gastó en total $487,5. b) Le dieron $112,5 de vuleto.

Step-by-step explanation:

1) Podemos encontrar el costo del helado como sigue:

T = J + A + H

H = T - J - A = 250 - 28,85 - 85,50 = 135,65

Por lo tanto, el helado costó $135,65.

2) a) Para saber cuanto dinero gastó debemos sumar todos los precios:

T = B_{p} + B_{g} + P = 349,50 + 108,25 + 29,75 = 487,5

Entonces, gastó en total $487,5.

b) Si pagó con $600, su vuelto fue:

V = 600 - T = 600 - 487,5 = 112,5

Le dieron $112,5 de vuleto.

Espero que te sea de utilidad!

GIven the function f(x) = 3x +1: (A) Find the inverse of f^-1(x). (B) Find f^-1(6)
Pani-rosa [81]

The inverse function is equal to f-1(x) = (x - 1)/3 and the value at f-1(6) is equal to 5/3.

To find the inverse, you need to switch the f(x) and x in the equation. Then you can solve for the new f(x). The result will be the inverse (f-1)

f(x) = 3x + 1 ----> Switch f(x) and x

x = 3f(x) + 1 ----> Subtract 1

x - 1 = 3f(x) ----> Divide by 3.

f-1(x) = (x - 1)/3

Now that we have the inverse, we can plug 6 in to get the value at f-1(6).

f-1(x) = (x - 1)/3

f-1(6) = (6 - 1)/3

f-1(6) = 5/3

exis [7]

Answer:

C. The meeting will be in Los Angeles California on July, 17.

Step-by-step explanation:

This doesn't use commas correctly because there should be a comma after Los Angeles because it is a location. Also, there should not be a comma after 17 because the comma goes after the date when the year is included, which it is not.

9. Write The eQuaTION OF THE LINE THAT Passes THROUGH THE
lara31 [8.8K]

The final equation of line that passes through (9, 0) AND (0, -6) is:

y=\frac{2}{3}x-6

Further explanation:

The general form of equation of line is:

y=mx+b

Given

(x1,y1) = (9,0)

(x2,y2) = (0, -6)

We have to find the slope first:

m=\frac{y_2-y_1}{x_2-x_1}\\= \frac{-6-0}{0-9}\\=\frac{-6}{-9}\\=\frac{2}{3}

Putting the value of slope in general form

y=\frac{2}{3}x+b

To find the value of b, we have to put a point in the equation

Putting (9,0) in equation

0=\frac{2}{3}(9)+b\\0=2*3+b\\0=6+b\\b=-6

Putting the values of b and m in general form

The final equation of line that passes through (9, 0) AND (0, -6) is:

y=\frac{2}{3}x-6

Alex wrote the expanded form for the number 165.038 as 100+60+5+30+8. Was he correct? If not give expanded form.
oksano4ka [1.4K]

We have the next number

165038

The expanded form of the number is

100000+60000+5000+30+8

Also, we can verify that Alex was incorrect because if we do the sum of the expanded form that Alex calculated we obtain

\begin{gathered} 100+60+5+30+8=203 \\ \text{And }203\ne165038 \end{gathered}

Finally, the correct answer is

100000+60000+5000+30+8

PLS HELP ME ILL MARK BRAINLIST IF SOMEONE CAN HELP ME WITH THESE 2 QUESTIONS!!
Nat2105 [25]

Answer:

1. Andrew grew 4 5/12 inches in 2 years

2. Abbey rode her bike for 3 3/8 hours in 2 days.

Step-by-step explanation:

When adding fractions you must have a common denominator for both of them.

First make the mixed fraction, improper fractions.

1 3/4 = 7/4

2 2/3 = 8/3

7/4 x 3/3 = 21/12

8/3 x 4/4 = 32/12

21 + 32 = 53

53/12 = 4 5/12

1 3/4 = 7/4

1 5/8 = 13/8

7/4 x 4/4 = 28/16

13/8 x 2/2 = 26/16

26 + 28 = 54

54/16 = 3 3/8

I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!
