Answer:
-4.25
Step-by-step explanation:
The given number is 4.25 and we have to find the opposite of this number.
Opposite of a number is also known as additive inverse and it is defined as "if the sum of two numbers is zero then two numbers are opposite or additive inverse of each other"
For example, if x is a number then its opposite is -x.
and hence, x + (-x) = 0
Using this fact, we can conclude that the opposite of 4.25 is -4.25 because
4.25 + (-4.25)
= 4.25 - 4.25
=0
Answer:
1900
Step-by-step explanation:
1 kg = 1000g
1.2kg = x
<u>1</u><u> </u><u>kgx</u> = <u>1</u><u>2</u><u>0</u><u>0</u><u> </u><u>kg.g</u>
1kg. 1kg
x = 1200 g
1 decagram = 10g
40 decagram = x
<u>1</u><u> </u><u>dg.x</u> = <u>4</u><u>0</u><u>0</u><u> </u><u>dg.g</u>
1 dg. 1 dg
x = 400g
so the total= 1200g +300 + 400g=1900g
without the unit = 1900
I would start by breaking apart the 275 into 200, 70, and 5. Then I
would multiply 4 by each of those numbers, giving you 800, 280, and 20.
Then, I would add those number back together (800+280+20) and that gives
you a final answer of 1,100.
The expression that can be used would be...
4(200)+4(70)+4(5)
