Answer the following equation: 1/2(x + 20) = 17/4x + 4 (6 - x)

zzz [600]

So use distributive property
which is
a(b+c)=ab+ac so
1/2(x+20)=1/2x+10

and the other
4(6-x)=24-4x

so now we have
1/2x+10=17/4x+24-4x
convert -4x to -16/4x and add to the 17/4x
1/2x+10=1/4x+24
subtract 24 from boths ides
1/2x-14=1/4x
multily both sides by 4
2x-56=x
subtract x from both sides
x-56=0
add 56 to both sides
x=56

ii. A machine is sold for 7,000/-. The gross loss is 20% of the cost. What are the cost and gross loss?

aleksley [76]

Given:

Selling price of a machine = 7000/-

Gross loss = 20%.

To find:

The cost and gross loss.

Solution:

Let x be the cost of machine.

According to the question,

$x-20\%\text{ of }x=7000$

$x-\dfrac{20}{100}x=7000$

$x-0.2x=7000$

$0.8x=7000$

Divide both sides by 0.8.

$x=\dfrac{7000}{0.8}$

$x=8750$

So, the cost of the machine is 8750/-.

Now,

$\text{Gross Loss}=\text{Cost}-\text{Selling price}$

$\text{Gross Loss}=8750-7000$

$\text{Gross Loss}=1750$

Therefore, the gross loss is 1750/-.

approximate each irrational number to the nearest hundredth without using a calculator square root of 118 and 319

Strike441 [17]

Answer:

$\sqrt{118}\approx 10.86$

$\sqrt{319}\approx 17.86$

Step-by-step explanation:

Consider the provided number.

We need to find the approximate value of $\sqrt{118}$ to the nearest hundredth.

First find two perfect squares that the irrational number falls between.

$100$

118 is lying between 100 and 121, therefore the square root value of 118 will be somewhere between 10 and 11.

$\sqrt{100}$

$10$

118 is closer to 121 as compare to 100.

Therefore, $\sqrt{118}\approx 10.86$

Consider the number $\sqrt{319}$

First find two perfect squares that the irrational number falls between.

$289$

319 is lying between 289 and 324, therefore the square root value of 319 will be somewhere between 17 and 18.

$\sqrt{289}$

$17$

319 is closer to 324 as compare to 289.

Therefore, $\sqrt{319}\approx 17.86$

What is the value of x?<br> Enter your answer in the box

Marina CMI [18]

Answer:

x = 45º

Step-by-step explanation:

well since a triangle has to equal 180º

then we just have to subtract 88º and 55º from 180º

180 - 80 - 55 = 45

therefore, x = 45
