Answer:
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
1) x+y = 170
x-y = 26
2) Subtract the two equations from each other. Doing this you get 2y = 56.
So the value of y is 28. Then plug in the value of y into any of the two equations and solve for x.
x-28 = 26
x = 54
3) When writing solutions as an ordered pair, the x value always comes first followed by the y value. So it would be (54, 28).
Answer:
N is less than 2, (C)
Step-by-step explanation:
Divide both sides by -6, and since two negatives make a positive, you get n is less then 2.
The decrease rate is 33.3%
Solution : 32$ on sale , original price is 48%
The deceased rate is x
48 (1-X)=32
x= 0.333
the square of a negative number always be positive
eg: -2² = -2×-2 = (-×- = +) +4
the cube of a negative number always be positive
eg: -2³ = -2×-2×-2 = (-×-×- = +) -8
hope it helps...!!!
