Find the value of x.

Mathematics
1 answer:
nikklg [1K]2 years ago
5 0

Answer:

x = 13

Step-by-step explanation:

Sum or interior angles of a triangle is 180,

6x + 19 + 5x - 15 + 3x - 6 = 180

6x + 5x + 3x + 19 - 15 - 6 = 180

14x + 19 - 21 = 180

14x - 2 = 180

14x = 180 + 2

14x = 182

x = 182 / 14

x = 13

FIND THE GCF. Mathematics
Rom4ik [11]

The G.C.F of the given algebraic expression is; ⁴⁹/₆a xy

<h3>What is the G.C.F (Greatest Common Factor)?</h3>

The greatest common factor (GCF or GCD or HCF) of a set of whole numbers is the largest positive integer that divides evenly into all numbers with zero remainder. For example, for the set of numbers 18, 30 and 42 the GCF = 6.

We are given the algebraic expression;

(3 x y * 4x²y * ¹/₁ * 5x³y ^ z * 4)7a * 1/1 * 7*6

Expanding this further gives;

⁴⁹/₆a((3xy * 4x²y * 20x³y ^ z )

Now, the GCF of the terms inside the bracket would be x y. Thus, expanding the GCF  we have;

⁴⁹/₆a xy((3 * 4x * 20x²y^(z - 1))

A store has a 20% sale on everything. An item originally cost 350 AED. What is the sale price? Show your work of how you calcula
slega [8]

Answer:

Step-by-step explanation:

A store has a 20% sale on everything.

So since you are saving 20%, you will only be paying 80% of the original price.

To find the sale price use the following formula:

Sale price = 80% x original price

They told us the original price = 350 AED

This means:

Sale price = 80% x 350

I think it would be easiest to change 80% into a fraction if you don't have a calculator :)

80% = \frac{80}{100}  = \frac{4}{5}

This means that the

Sale Price= \frac{4}{5} x 350 = 280 AED

Answer:

<h2>62.832 mi.²</h2><h2></h2>

Step-by-step explanation:

surface area = 2πrh + 2πr²

where r = 2 miles radius

          h = 3 miles

<u>plugin values into the formula</u>

surface area = 2πrh + 2πr²

                     = 2π (2) 3  +  2π (2)²

                     = 37.699  +  25.133

                     = 62.832 mi.²
