Answer:

3 1st class tickets

5 coach tickets

Step-by-step explanation:

Quantity:: C + F = 8

Value:: 380C + 1180F = 5440

Modify;:

1180C + 1180F = 1180*8

380C + 1180F = 5440

Subtract and solve for "C"::

800C = 4000

C = 5 (# of coach tickets)

Let x = number of 1st class tickets

8-x = number of coach tickets

and

She bought 3 1st class tickets

She bought 5 coach tickets

Answer:

It is B) 11/4 - 6/4 = 5/4

Step-by-step explanation:

First off 2 3/4 as an improper fraction is 11/4 and the rest are improper fractions to

Next we know how much Maria poured in witch is 1 2/4 = 6/4. So Ansley poured in the rest.

Then we do 11/4 - 6/4 = 5/4 and that is your answer

Answer:

67.6

Solving Steps:

=> 2x³ + 3.4y

=> 2(3)³ + 3.4(4)

=> 2(27) + 13.6

=> 54 + 13.6

=> 67.6

Hey there!

1/2x^3 + 3.4y

= 1/2(3)^3 + 3.4(4)

= 1/2(3 * 3 * 3) + 3.4(4)

= 1/2(9*3) + 3.4(4)

= 1/2(27) + 3.4(4)

= 27/2 + 3.4(4)

= 13.5 + 13.6
= 27.1

Therefore, your answer is: 27.1

Good luck on your assignment & enjoy your day!

Answer:

18 cups

Step-by-step explanation:

Because there is 4 cups in a quart, we can turn 5 1/2 or 5.5 quarts into 22 cups:

5 1/2 or 5.5

( 5 x 4) + (0.5 x 4) = 22

Since we need to find how many cups were used, that is x. Because 22 cups is the total amount of cups and 4 is the amount remaining then the equation would look like this:

x + 4 = 22

Finally you solve to get:

x = 18 cups

Answer:

A power of 10 is as many number 10s as indicated by the exponent multiplied together.

Step-by-step explanation:
Thus, shown in long-form, a power of 10 is the number 1 followed by n zeros, where n is the exponent and is greater than 0; for example, 106 is written 1,000,000.

Answer:10 of the power means you add on the zeros

Step-by-step explanation:

say if your question says 10 to the 4 power it would be 10,000 because the power stands for the zeros in your answer.

Answer:

-16

Step-by-step explanation:

As we have

[tex] {x}^{2} - {y}^{2} = (x + y)(x - y)[/tex]

Here

x= -3

y= -5

Subtitute x and y

[tex] {x}^{2} - {y}^{2} \\ ( - 3{)}^{2} - ( - 5 {)}^{2} \\ 9 - 25 \\ - 16[/tex]

Answer:

-16

Step-by-step explanation:

We first need to substitute

Since x = -3 and y = -5

(-3+-5)(-3 - -5)

Let's Solve (-3+-5)

which = -8

Then Solve (-3 - -5)

which = 2

Now -8 × 2 = -16

Hence, Answer = -16

Solution:

We know that:

Step by step calculations:

1. Substitute the angles in the equation "∠A + ∠B + ∠C = 180" to find ∠C:

2. Substitute ∠C in the equation "∠C + n = 180" to find n:

3rd side:: x + 6

Perimeter = x + 2x+5 + x+6 = 4x + 11

Answer:

C. y = 3x + 14

Answer:

A. y = 3x – 10

Step-by-step explanation:

We have equation of line passing through two points (x1, y1) and (x2, y2) as,

(y - y1) = [(y2 - y1)/(x2 - x1)] (x - x1)

(y + 4) = [(2 + 4)/(4 - 2)] (x - 2)

(y + 4) = (6/2)(x - 2)

(y + 4) = 3(x - 2)

3x - y - 10 = 0 --- (1)

Now, slope-intercept form of line is y = mx + c

Rearranging equation (1) ⇒ y = 3x - 10

Therefore, the required equation is y = 3x - 10

Answer:

Result: $26.46

Steps:

$24.50 (increase) + 8% = $26.46

24.50 x (1 + 8%) = 24.50 x (1 + 0.08) = 26.46

I'm truly sorry if my math is incorrect.

Bye, have a great day/night  :)

Answer:

$26.46

Step-by-step explanation:

1 example $24.50*(108%)

24.5*1.08

= $26.46

2nd example 24.5+1.96=26.46

Also 8% of 24.5 is 1.96

Answer:

16

Step-by-step explanation:

Line 1: ◄ + ◄ + ◄ = 30

3◄ = 30

◄ = 10

The triangle equals 10.

Line 2: ◄ + ◘ + ◘ = 18

10 + 2◘ = 18

2◘ = 8

◘ = 4

The square equals 4.

Line 3: ◘ - ○ = 2

4 - ○ = 2

-○ = -2

○ = 2

The circle equals 2.

○ + ◄ + ◘ = 2 + 10 + 4 = 16

Answer: 16
