Answer:
7 and 1.8
Step-by-step explanation:
Absolute value is easy the answer is always the number in the absolute value but it can never be negative so if it's l-2l then the answer is 2 l-1000l the answer is 1000
$0.79
Explanation:
1.58/2= 0.79
Answer:
and
Step-by-step explanation:
Move the constant to the right-hand side and change their sign.
combine like terms
Square both side to remove square brackets.
10y + 24 - 3 = y²+ 8y + 16
Move the expression to the left-hand side and change its sign.
10y + 24 - y² - 8y - 16 = 0
Combine like terms
10y - 8y + 24 - 16 - y² = 0
2y + 8 - y² = 0
Use commutative property to reorder the terms.
-y² + 2y + 8 = 0
Change the sign of expression.
y² -2y -8 = 0
split -2y
<u>y² + 2y </u>- <u>4y - </u><u>8</u> = 0
Factor out y from the first pair and -4 from the second equation.
y ( y + 2 ) - 4 ( y + 2 ) = 0
Factor out y+2 from the expression.
( y + 2 ) ( y - 4)
When the products and factors equals 0, at least one factor is 0.
y + 2 = 0
y - 4 = 0
Solve for y
y = -2
y = 4
When we plug the both solution as y we found that both is true solution of this equation.
This equation has two solutions which are -2 and 4.
The hundred-thousandth place is where the x is _x_,___.
You can round a number by taking the number to the right of it and seeing if it's over 5. If it is, you can make the number one higher, if not, then the number stays the same.
867,000 rounded to the nearest hundred-thousandth is 860,000.
Answer:
4500 pages
Step-by-step explanation:
an hour has 60 minutes. This means in 1 hour the machine will scan 60/15 more pages. 60/15 =4.
1125*4 =4500 pages/hour
