Answer:
X= 2.5 Y= 3.5
Step-by-step explanation:
2X+3Y =15.5
replace either x or y with your second equation
(2*(6-y))+3y=15.5
now you only have one variable
12-2y+3y=15.5
y=3.5
now insert your y value into the second equation provided
x+y=6
x+3.5=6
so x= 2.5
you can check your answer by inserting these numbers into the equations and it should work
Since the prefix centi- means 100, 1 gram is equivalent to 100 centigrams. You have to multiply 30 grams by 100 to get the number of centigrams.
30 * 100 = 3000
So, 30 grams is equivalent to 3000 centigrams.
Hope this helps! :)
Answer:
(- 1, 1 )
Step-by-step explanation:
given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( , )
here (x₁, y₁ ) = A (2, 4 ) and (x₂, y₂ ) = C (- 4, - 2 ) , then
midpoint = ( , ) = ( , ) = (- 1, 1 )
11/5 x 3/20
Simplify to 11/1 x 3/4
33/4
The answer is 7.3. Hope that helps.
