Matthew decided to bake cupcakes for the school fundraiser. He wants to make 2 dozen cupcakes--one dozen strawberry and one doze
Alchen [17]

Answer:

4+c=2\frac{1}{4}+2\frac{1}{3},\\\\\frac{7}{12}\:\text{more cups of flour}

Step-by-step explanation:

The total amount of flour, in cups, Matthew needs is equal to 2\frac{1}{4}+2\frac{1}{3}=4\frac{7}{12}. Because he only has 4 cups, we can write the following expression to determine how many additional cups of flour he needs:

4+c=2\frac{1}{4}+2\frac{1}{3},\\\\4+c=\frac{7}{12}, \\\\c=\boxed{\frac{7}{12}\:\text{more cups of flour}}

Find an equation of the line that passes through (3,4) and parallel to 4x-2y=5
Alex73 [517]
       4x - 2y = 5
4x - 4x - 2y = -4x + 5
             -2y = -4x + 5
              -2         -2
                y = 2x - 2¹/₂

          y - y₁ = m(x - x₁)
           y - 4 = 2(x - 3)
           y - 4 = 2(x) - 2(3)
           y - 4 = 2x - 6
             + 4        + 4
                y = 2x - 2

How do i factor the coefficent out of a variable, such as 2.4n+9.6 and -6z+12
ANEK [815]
You are factoring one or more linear expressions (but are not factoring variables).

2.4n+9.6 can be divided by 2.4 and then the result mult. by 2.4:

2.4n+9.6 = 2.4 [ n + 4 ]

Also:  -6z+12= 6 [ -z + 2 ]  Here I have simplified linear functions but factoring out common constant coefficients (not variables).
