What is 7 over 8 plus 3 over 4 minus 1 over 3

Otrada [13]

Answer:

1 7/24.

Step-by-step explanation:

7/8 + 3/4 - 1/3 The LCD of 3,4 and 8 is 24 so we have:

21/24 + 18/24 - 8/24

= 39/24 - 8/24

= 31/24

= 1 7/24.

Can someone plz help me plz

almond37 [142]

Answer:

$\large\boxed{C.\ y=2+x^4}$

Step-by-step explanation:

The slope-intercept form of an equation of linear function:

$y=mx+b$

<em>m</em> - slope

<em>b</em> - y-intercept

============================

$A.\\\\9y+3=0\qquad\text{subtract 3 from both sides}\\\\9y=-3\qquad\text{divide both sides by 9}\\\\y=-\dfrac{3}{9}\\\\y=-\dfrac{1}{3}\to m=0,\ b=-\dfrac{1}{3}$

$B.\\\\y-4x=1\qquad\text{add}\ 4x\ \text{to both sides}\\\\y=4x+1\to m=4,\ b=1$

$C.\\\\y=2+x^4\qquad\text{nonlinear, because}\ x\ \text{is in fourth power}$

$D.\\\\x-2y=7\qquad\text{subtract}\ x\ \text{from both sides}\\\\-2y=-x+7\qquad\text{divide both sides by (-2)}\\\\y=\dfrac{1}{2}x-\dfrac{7}{2}\to m=\dfrac{1}{2},\ b=-\dfrac{7}{2}$

$E.\\\\\dfrac{x}{y}+1=2\qquad\text{subtract 1 from both sides}\\\\\dfrac{x}{y}=1\to y=x\to m=1,\ b=0$

4(3n-2)^(-3/2)+1=347/343

blagie [28]

Greetings and Happy Holidays!

Solve for n.
$4(3n-2)^{\frac{-3}{2}}+1= \frac{347}{343}$

Add -1 to both sides.
$(4(3n-2)^{\frac{-3}{2}}+1)+(-1)=(\frac{347}{343})+(-1)$

$4(3n-2)^{\frac{-3}{2}}=\frac{347}{343}-1$

$4(3n-2)^{\frac{-3}{2}}=\frac{347}{343}-\frac{343}{343}$

$4(3n-2)^{\frac{-3}{2}}=\frac{4}{343}$

Divide both sides by 4
$\frac{4(3n-2)^{\frac{-3}{2}}}{4}=\frac{\frac{4}{343}}{4}$

$\frac{4(3n-2)^{\frac{-3}{2}}}{4}=\frac{4}{343}(\frac{1}{4})$

$\frac{4(3n-2)^{\frac{-3}{2}}}{4}=\frac{4}{1372}$

$\frac{4(3n-2)^{\frac{-3}{2}}}{4}=\frac{1}{343}$

$(3n-2)^{\frac{-3}{2}}=\frac{1}{343}$

Solve the Exponent.
$((3n-2)^{\frac{-3}{2}})^{\frac{2}{-3}} =\frac{1}{343}^{\frac{2}{-3}}$

$3n-2=49$

Add 2 to both sides.
$(3n-2)+2=(49)+2$

$3n=51$

Divide both sides by 3.
$\frac{3n}{3}= \frac{51}{3}$

$n=17$

The Answer Is:
$\left[\begin{array}{ccc}n=17\end{array}\right]$

Hope this helped!
