What is $0.1369 rounded to the nearest cent
makvit [3.9K]
Ok, what is $0.1369 rounded to the nearest cent? 

100 cents make a dollar which means the most possible cents not making a dollar is 99 cents

So that means you leave the first two decimals alone and focus on the last two.

What is 69 closer to? 70 or 60? Well, its larger than 65 which is the halfway point so its closer to 70

Is 70 closer to 0 or 100? Well, since 70 is past the halfway point which is 50, its closer to 100.

Think of 3 as 0 and the next number up which is 4 as 100, well, since 70 is closer to 100 than 0, its closer to 4.

So That means that 0.1369 rounded to the nearest cent is $0.14

Your answer rounded is $0.14

Which order pair lies on the line 2x-y= -5
Lady bird [3.3K]

Answer:

Let's solve for x.

2x−y=−5

Step 1: Add y to both sides.

2x−y+y=−5+y

2x=y−5

Step 2: Divide both sides by 2.

2x/2=y-5/2

Answer:

x=1/2y+-5/2

What is equivalent to<br> -9(x - 4 ) - 6x
Lapatulllka [165]
The answer would be -15x+36. To solve this equation, you would first use distributive property and distribute the -9 to the values inside the parentheses (or multiply them). So, you would multiply -9 and x and -9 and -4 to get -9x+36-6x. Then, you combine like terms, which are -9x and -6x to get -15x. You can't simplify any further without knowing the value of x. Hope this helps!
