For this case we have the following equation:

2m + \frac {7} {4} (\frac {3} {4} m- \frac {5} {2}) = \frac {3} {32} + \frac {1} {3} m

We apply distributive property on the left side of the equation:

2m + \frac {21} {16} m- \frac {35} {8} = \frac {3} {32} + \frac {1} {3} m

We add similar terms from the left side:

\frac {53} {16} m- \frac {35} {8} = \frac {3} {32} + \frac {1} {3} m

Add\frac {35} {8}to both sides:

\frac {53} {16} m = \frac {3} {32} + \frac {1} {3} m + \frac {35} {8}

We subtract \frac {1} {3} m from both sides:

\frac {53} {16} m- \frac {1} {3} m = \frac {3} {32} + \frac {35} {8}\\\frac {143} {48} m = \frac {1144} {256}\\143m = \frac {1144 * 48} {256}

We simplify:

143m = \frac {54912} {256}\\143m = \frac {13728} {64}\\143m = \frac {3432} {16}\\143m = \frac {858} {4}\\143m = \frac {429} {2}

We divide between 143 on both sides:

m = \frac {429} {2 * 143}\\m = \frac {429} {286}\\m = \frac {33} {22}\\m = \frac {3} {2}

Answer:

m = \frac {3} {2}

Factor the expression.
g100num [7]

Answer:

(x + 1) (3 x^2 + 1)

Step-by-step explanation:

Factor the following:

3 x^3 + 3 x^2 + x + 1

Factor terms by grouping. 3 x^3 + 3 x^2 + x + 1 = (3 x^3 + 3 x^2) + (x + 1) = 3 x^2 (x + 1) + (x + 1):

3 x^2 (x + 1) + (x + 1)

Factor x + 1 from 3 x^2 (x + 1) + (x + 1):

Answer:  (x + 1) (3 x^2 + 1)

Solve the system using substitution and describe your steps. <br> x=y-3 <br> 2x+y=12
Veseljchak [2.6K]
First you plug in for x,

2(y-3)+y=12

Then you solve for y
2y-5+y=12
-10y+y=12
-9y=12
-9y/9=12/-9
y=-1.333333333333333333333333333333333333333333333333333333333

Find a formula for the sum of the first n even positive integers.
melisa1 [442]
So even postive integers are by defention in form 2k where k is a natural number so
let the sum of even integers to n=S
S=2(1+2+3+4+5+6+7+8+......+k-1+k
divide bith sides of equation 1 by 2
0.5S=1+2+3+4+5+...........+k-1+k
S=2(k+(k-1)+..............................+2+1)
divide both sides of equation 2 by 2
0.5S=k+k-1+..............................+2+1)
by adding both we will get
___________________________
S=(k+1)(k)
so the sum will be equal to
S=
{k}^{2}  + k
so let us test the equation
for the first 3 even number there sums will be
2+4+6=12
by our equation 3^2+3=12
gave us the same answer so our equation is correct
