To solve for f, you need to isolate/get the variable by itself in the equation:

4(0.5f - 0.25) = 6 + f       Distribute 4 into (0.5f - 0.25)

(4)0.5f + (4)(-0.25) = 6 + f

2f - 1 = 6 + f        Subtract f on both sides to get "f" on one side of the equation

2f - f - 1 = 6 + f - f

f - 1 = 6       Add 1 on both sides to get "f" by itself

f - 1 + 1 = 6 + 1

f = 7

PROOF

4(0.5f - 0.25) = 6 + f      Substitute/plug in 7 into "f" since f = 7

4(0.5(7) - 0.25) = 6 + 7

4(3.5 - 0.25) = 13

4(3.25) = 13

13 = 13

Use distributive property to rewrite problem so it had only two factors. Then solve (25x9)+(75x9)=
Shalnov [3]

ANSWER

(25\times9)+(75\times9)=9(25+75)


(25\times9)+(75\times9)=9(100)


(25\times9)+(75\times9)=900


EXPLANATION


According to the distributive property,

(a\times b)+(a\times c)=a(b+c)

This implies that,

(25\times9)+(75\times9)=9(25+75)


(25\times9)+(75\times9)=9(100)

The Right Hand Side of the equation now has 2 factors.


We solve now to obtain;


(25\times9)+(75\times9)=900
