Answer
28 ounces = 793.79 grams
28 ounces = 0.79 kilograms.
Step by step explanation
1 ounce = 28.3495 grams
Now let's convert 28 into grams.
Here we have to multiply 28 by 28.3495
28 x 28.3495 = 793.787 grams
Now let's convert 793.787 into kilograms
1 kilograms = 1000 grams
793.787 grams = 0.79 kilograms
2 = 2????
Thats what Im getting it from.
Since x is 2 then it would still be 2=2 in simple term.
Answer:
a = 1
b = -1
Step-by-step explanation:
First, let's make equations out of those given f(x)'s
-4 = -3a + b
2 = 3a + b
We can use elimination method to get rid of the a real quick
-4 = b
2 = b
Add those together
-2 = 2b
Divide both sides by 2
-2/2 = 2b/2
b = -1
Plug in the new b in one of the original equations; I'm gonna use the bottom one
2 = 3a - 1
+ 1 + 1
3 = 3a
3/3 = 3a/3
a = 1
