1 kilogram= 1,000 grams
2 kilograms= 2,000 grams
1,000/2=500
2,000+500=2,500 grams
2.5 kilograms= 2,500 grams.
Hope this helps!! :)

Answer:
x = 117.9°
Step-by-step explanation:
We require to find the size of the angle x
Given the law of cosines
c² = a² + b² - 2ab cosC
Rearrange to give cosC in terms of the sides
Add 2ab cosC to both sides
c² + 2ab cosC = a² + b² ( subtract c² from both sides )
2ab cosC = a² + b² - c² ( divide both sides by 2ab )
cosC =
here a = 55, b = 50 and c = 90 and C = x
cosx =
=
= ← - indicates angle is obtuse
x = ( ) ≈ 117.9°
Answer:
4
Step-by-step explanation:
To find the slope, you need to use the following equation:
For x₂ and y₂, I picked 5 and 20. For x₁ and y₁, I picked 3 and 12. It doesn't matter which points you pick to plug in. You will get the same answer regardless.
Your slope is equal to 4.

Answer:
So first lets find g(-1)
so we plug in the answers:
-2 * -1 ^2 -4
-2*1-4 = -2-4 =
-6
Now lets solve for f(-2)
-2^2-3
4-3=1
-6+1 = 5
3*5 = 15
Im getting answer of 15 but it shows -15 or something, so I dont know if I got it wrong or if its like a dash then the answer.
