M is 3/2 because we need to Multiply to remove the variable from the denominator
Answer:
8
Step-by-step explanation:
To solve this, you can add 2/5 b to both sides of the equation. You now have 3 + 5/5 (or 1) b = 11. => 3 + b = 11 => Now, subtract 3 from both sides, and you have b = 11 - 3, and then b = 8.
Answer:
b) 4 3/8
Step-by-step explanation:
we know that
12 muffins calls for 1 3/4 cups of flour
using proportion
Find out how much flour will be needed in the mix for a bath of 30 muffins
Convert mixed number to an improper fraction
substitute
convert to mixed number
If this is a system of equations then:
Multiply 5x-y=3 by -2
=> -10x+2y=-6
Now you sum the equations:
10x-10x+7y+2y=-3-6
=> 9y=-9
Then just divide by 9: y=-1
Now to get x, choose one of the equations and use the value we got from y:
5x-(-1)=3 => 5x+1=3 => 5x=3-1
=> 5x=2
=> x=2/5
(x,y)=(2/5, -1)
