Answer:
b₂ = 5
Step-by-step explanation:
Substitute the given values into the formula
16 = 
× 4 × (3 + b₂)
16 = 2(3 + b₂) ( divide both sides by 2 )
8 = 3 + b₂ ( subtract 3 from both sides )
5 = b₂
Each student gets 1/8 of the cake.
we multiply 1/8 and 3/4. To do that we multiply the numerators together and the denominators together. This gives (1*3)/(8*4) =3/32 of the cake
Answer:
c
Step-by-step explanation:
Answer:
2x + y = 17
-6x = 3y - 51
Step-by-step explanation:
You get an infinite number of solutions when two equations are really just the same. This means you can convert one into the other simply by multiplying one to get the other.
In the above answer, if you multiply the above by -3 you get:
-6x -3y = -51
which is of course -6x = 3y - 51
So that is an example of a pair that has infinite solutions.
To find all of them, you'd carefully have to compare each 2 and see if there is a multiplier to convert one into the other. You can do that!
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
- 4x + 3y = 12 ( add 4x to both sides )
3y = 4x + 12 ( divide the terms by 3 )
y = 
x + 4 ← in slope- intercept form
with slope m = and y- intercept c = 4
---------------------------------------------------
Given
- 5x + 3y = - 9 ( add 5x to both sides )
3y = 5x - 9 ( divide the terms by 3 )
y = 
x - 3 ← in slope- intercept form
with slope m = and y- intercept c = - 3
