Fraction would be 30/100 and decinal would be .30 and ratio would be 30/100

2.) the fraction is 3/10 because there are 100 blocks and 30 of them are filled
Decimal is .3 because it is 30% of 100
The ratio is 3:10

3.) part is 40 because 50% of 80 is 40 and whole is 80 because that’s the full number without the percentage, percentage is 50 because 50% is the percentage you have to get this means it’s 40/80 = 50/100 we know this is correct because they both simplify to 1/2=50%

What is the missing step in solving the inequality 5 – 8x < 2x + 3? Add 2x to both sides of the inequality. Subtract 8x from

kvasek [131]

Answer:

⇒ Add 8x to both sides of the inequality

⇒ x>1/5

Step-by-step explanation:

First, you subtract by 5 from both sides of equation.

5-8x-5<2x+3-5

Solve.

-8x<2x-2

Then subtract by 2x from both sides of equation.

-8x-2x<2x-2-2x

Solve.

-10x<-2

Multiply by -1 from both sides of equation.

(-10x)(-1)>(-2)(-1)

Solve.

10x>2

Divide by 10 from both sides of equation.

10x/10>2/10

Solve to find the answer.

2/10=10/2=5 2/2=1=1/5

x>1/5 is final answer.

Hope this helps!

Find the number set which satisfies each of the problems. If 20 is added to the number, the absolute value of the result is 6.

victus00 [196]

Answer: {-14,-26}

Step-by-step explanation:

Let x be the number.

Given statements: If 20 is added to the number, the absolute value of the result is 6.

i.e. |x+20| =6

Since $|y|=c \Rightarrow y= c \text{ or } y = -c$

So, $|x+20| =6\Rightarrow\ x+20=6\text{ or }x+20=-6$

$\Rightarrow\ x= 6-20\text{ or } x= -6-20\\\\\Rightarrow\ x=-14\text{ or } x=-26$

hence, set of values of x = {-14,-26}
