Answer:

$-\frac{4}{5}$

Step-by-step explanation:

There is not much that can be done to figure out how to write 0.8 as a fraction, except to literally use what the decimal portion of your number, the .8, means.

Since there are 1 digits in 8, the very last digit is the "10th" decimal place.

So we can just say that .8 is the same as 8/10.

The fraction is not reduced to lowest terms. We can reduce this fraction to lowest terms by dividing both the numerator and denominator by 2.

Why divide by 2? 2 is the Greatest Common Divisor (GCD) or Greatest Common Factor (GCF) of the numbers 8 and 10.

So, this fraction reduced to lowest terms is 4/5

So your final answer is: 0.8 can be written as the fraction 8/10 simplified to 4/5

Answer:

(B) 2

Step-by-step explanation:

=> $\frac{\sqrt{32}+ \sqrt{48} }{\sqrt{8}+\sqrt{12} }$

=> $\frac{4\sqrt{2}+4\sqrt{3} }{2\sqrt{2}+2\sqrt{3} }$

=> $\frac{4(\sqrt{2}+\sqrt{3}) }{2(\sqrt{2}+\sqrt{3)} }$

Cancelling $\sqrt{2}+\sqrt{3}$

=> $\frac{4}{2}$

=> 2

What is the solution to the equation 3x-5=2x+8+x?

Marysya12 [62]

So when solving this you are going to have to solve the equation.
Okay so first thing we need to do is simplify both sides of your equation so:
3x−5=2x+8+x
Simplifying process:
3x+−5=2x+8+x
Combine Like Terms ⇒ 3x−5=(2x+x)+(8)
3x−5=3x+8
3x−5=3x+8
Second thing we are now going to do is subtract 3x from both sides so:
3x−5−3x=3x+8−3x
−5=8
Final step is to add 5 to both sides:
−5+5=8+5
0=13
The answer to your question is "There are no solutions"

Oliver had m dollars to spend on a backpack for the new school year. The expression below represents the amount of money he had

xxMikexx [17]

Answer:

Option A

Step-by-step explanation:

Y is the amount of back pack

The total amount is represented by m

If Y is the cost of back pack purchased by Oliver, then 0.7 Y is the tax applicable on the purchase of back pack

Hence, the remaining cost would be total amount with Oliver minus the cost of back pack and the tax applicable on the purchase of back pack

Remaining cost = m - (y + 0.07y)

Hence, option A is correct
