Answer:
-7 + 8 m + 4 n thus A. is your Answer
Step-by-step explanation:
Expand the following:
-(-8 m - 4 n + 7)
-(7 - 8 m - 4 n) = -7 - -8 m - -4 n:
-7 - -8 m - -4 n
-(-8) = 8:
-7 + 8 m - -4 n
-(-4) = 4:
Answer: -7 + 8 m + 4 n
Answer: Cole and his sister Chloe will take 81 minutes to clean the whole house.
Step-by-step explanation:
Total rooms in the house = 9
Total persons to clean the house = 2 (Cole and his sister Chloe)
Time taken by 1 person to clean one=18 minutes
Time taken by 2 persons to clean one room together=18 divided by 2 = 9 minutes
Time taken by 2 persons to clean 9 rooms (which is the total number of rooms in the house)=9 multiply 9 = 81 minutes
therefore, they will take 81 minutes to clean the whole house.
X = 10
to find x -
7x = 8x - 10
180 - 70 = 110
110 = 6y + 20
y = 15
Answer:
So that's actually not true. When comparing decimals you should compare each digit. Remember adding a 0 at the end does not change the value of the decimal. So lets look at it up and down:
remember line up the decimal to decimal
<u>1</u>.628
<u>1</u>.630
the first digit is the same. Both of these numbers are also before the decimal.
let's look at the second digit.
1.<u>6</u>28
1.<u>6</u>30
they are also the same. Both of these are also right after the decimal point.
now let's look at the third digit.
1.6<u>2</u>8
1.6<u>3</u>0
In this case, the bottom number has a higher value. Since 3>2, the bottom number is the overall biggest. Or you could look at it and say "Oh! 30 is bigger than 28!" I hope this helps you, and if this wasn't what you were looking for, oops
