solve for x for the triangle

Answers

Step-by-step explanation:

90° + 2x-2 + x+5 = 180° [Angle sum property of triangle]

=> 90 + 2x + x - 2 + 5 = 180°

=> 3x + 93 = 180

=> 3x = 180 - 93

=> 3x = 87

[tex] = > x = \frac{87}{3} [/tex]

=> x = 29 (Ans)

On a particular flight, the airline's income was $95,280 for a jumbo jet carrying 290 passengers. If a first-class ticket costs $680 and a coach ticket costs $288, how many of each ticket were sold for the flight?

Answers

Answer:

30 first-class tickets were sold and 260 coach tickets were sold.

Step-by-step explanation:

Let a first-class ticket be represented by f and let a coach ticket be represented by c.

On a particular flight, a jumbo jet was carrying 290 passengers. So, the sum of the first-class tickets and coach tickets must sum to 290:

[tex]f+c=290[/tex]

The total income was $95,280. Therefore:

[tex]680f+288c=95280[/tex]

We can now solve the system of equations. First, we can simplify the second equation by dividing everything by 8:

[tex]85f+36c=11910[/tex]

From the first equation, we can subtract f from both sides:

[tex]c=290-f[/tex]

Substitute:

[tex]85f+36(290-f)=11910[/tex]

Distribute:

[tex]85f+10440-36f=11910[/tex]

Simplify:

[tex]49f=1470[/tex]

So:

[tex]f=30[/tex]

From the previous equation:

[tex]c=290-f[/tex]

Substitute:

[tex]c=290-30=260[/tex]

30 first-class tickets were sold and 260 coach tickets were sold.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, 20 yards of carpet weighs 30 pounds.

Here, 1 yard of carpet weighs = 30/20

= 1.5 pounds

34 yards of carpet weighs

= 34×1.5

= 51 pounds

Therefore, 34 yards of carpet weighs 51 pounds.

Unit conversion is a way of converting some common units into another without changing their real value. Ms. Aluma is using the correct option.

What is Unit conversion?

Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.

Given that Ms Aluma is 165 cm tall and She wants to find her height in meters. Therefore, if we divide her height in centimeters by 100 to find her height in meters.

Since 1 meter is equal to 100 cm, therefore, the method used by Ms. Aluma is correct. Therefore, the height of Unit conversion is,

Height of Ms. Aluma = 165 cm

                                  = 165/100 meters

                                  = 1.65 meters

Hence, Ms. Aluma is using the correct option.
