FOR BRAINLIEST<br> Express 0.64 as a fraction in lowest terms.<br> 5/32<br> 64/10<br> 16/25<br> 4/5
Nadusha1986 [10]

Answer:In its decimal form, it says  ' 64 / 100 '.

In order to change it to its lowest terms, we look to see whether the

numerator and denominator have a common factor greater than ' 1 '.

If they do, then we can divide numerator and denominator by their

common factor, and have the same fraction in lower terms.

The common factors of  64  and  100  are  1,  2, and  4 .

We could divide top and bottom by 2, but that wouldn't finish the job.

It's always best to divide them by their greatest common factor, and

once you do that, you're done.

Dividing the numerator and denominator both by  4,

we get the fraction in its lowest terms:

        0.64  =  64/100  =  16/25

What is 6.7086 rounded to the nearest tenth
padilas [110]
Hello!

Decimals used to confuse me a lot! :D 

When a question asks to round the decimal to the "nearest tenth", it simply means to round it to one decimal place.

6.7086 would be rounded to 6.7 if we round it to the nearest tenth. See, the 7 is in one place after the decimal point. 

The best way to understand decimal places, in my opinion, is to search up a tenths, hundredths, thousandths, etc. chart. Hope this gave you a better understanding of decimal places!

16. Find the values of x and y. (2y + 5) (5x - 17) (3x – 11)º
Iteru [2.4K]

Answer:

x = 26

y = 9

Step-by-step explanation:

(5x - 17)° + (3x - 11)° = 180° (angles in a straight line)

Solve for x

5x - 17 + 3x - 11 = 180

Collect like terms

5x + 3x - 17 - 11 = 180

8x - 28 = 180

Add 28 to both sides

8x = 180 + 28

8x = 208

Divide both sides by 8

x = 208/8

x = 26

Also:

(2y + 5)° + 90° + (3x - 11)° = 180° (angles on a straight line)

Plug in the value of x and solve for y

2y + 5 + 90 + 3(26) - 11 = 180

2y + 5 + 90 + 78 - 11 = 180

Collect like terms

2y + 162 = 180

Subtract 162 from both sides

2y = 180 - 162

2y = 18

y = 9 (dividing both sides by 2)
