Oxana [17]3 years ago

Answer:

x = 3

Step-by-step explanation:

First, multiply all four terms by 10 to eliminate the fractions:

4x - 8(x-4) = 13x - 19

Next, carry out the indicated multiplication, obtaining:

4x - 8x + 32 = 13x - 19

Combining the x terms, we get:

-4x + 32 = 13x - 19, or

        32 = 17x - 19

Combining the constants, we get 51 = 17x, and so x = 51/17 = 3.

Find the area of the regular polygon
olasank [31]

area = 44.0467 \: cm {}^{2}

<h3>step by step explanation </h3>

● area of regular polygon Formulas ,

⟹a = \frac{l^{2}n}{4tan(\frac{\pi }{n)}}

● now finding the area of regular polygon,

⟹\frac{4 {}^{2} \times 8 }{ 4 \: tan \:  \binom{180}{5} }

⟹a =  \frac{128}{4 \times 0.7265}

⟹a = 44.0467 \: cm {}^{2}

sveticcg [70]

Answer:

33

Step-by-step explanation:

Given that :

Card numbered from: 500 - 799

The required number of values must meet both conditions 1 and 2

Condition 1 : first of the 3 digits is odd :

500 - 599 = 100

700 - 799 = 100

(100 + 100) = 200 cards

Condition 2: three digits is divisible by 6

{500 - 599} and {700 - 799}

The numbers divisible by 6 are 33
