always remember

\sqrt[i]{ {a}^{b} }  =  {a}^{ \frac{b}{i} }

except in cases that <i> is even & b is less than zero, or A will have a negative power.

here you have:

{x}^{ \frac{1}{3} +  \frac{5}{2}  + 1 } \div  {x}^{ \frac{1}{2} }

and a simple job:

\frac{1}{3}  +  \frac{5}{2}  + 1 -  \frac{1}{2 }  =  \frac{1}{3 }  +  \frac{4}{2}  + 1 = 3  +  \frac{1}{3}

finally answer is:

{x}^{ \frac{10}{3} }  =  {x}^{3}   \sqrt[3]{x}

Raina's penny bank is  1/4  full. After she adds  360  pennies, it is  5/8  full. How many pennies can Raina's bank hold? ​
Triss [41]

Answer:

960

Step-by-step explanation:

We start with the variable "x". Let's call "x" Raina's penny bank.

After adding 360 pennies, at the end, she has 5/8x, or 5/8.

So we start with

(1/4)x + 360 = 5/8x

Let's subtract 1/4x from both sides

360 = 5/8x - 1/4x

Remember, we need to use common denominators to subtract, so 1/4 becomes 2/8

360 = 5/8x - 2/8x

Now we simplify to get

360=3/8x

Multiply the reciprocal of 3/8 to both sides which is 8/3

360 * 8/3 = x

Answer is 960 pennies.

Therefore Raina's bank hold 960 pennies.

-5x-y= 8<br> -4x+y=2 solve the system
yan [13]

\huge\fcolorbox{blue}{aqua}{Answer:}

═════════════════════

1.- 5x - y = 8

<h3>Solve for x</h3>

-5x-y=8

-5x=8+y

-5x=y+8

\frac{-5x}{-5}=\frac{y+8}{-5}

x=\frac{y+8}{-5}

x=\frac{-y-8}{5}

<h3>Solve for y</h3>

-5x-y=8

-y=8+5x

-y=5x+8

\frac{-y}{-1}=\frac{5x+8}{-1}

y=\frac{5x+8}{-1}

y=-5x-8

────────────────────

2.-4x-y=2

<h3>Solve for x</h3>

-4x-y=2

-4x=2+y

-4x=y+2

\frac{-4x}{-4}=\frac{y+2}{-4}

x=\frac{y+2}{-4}

x=-\frac{y}{4}-\frac{1}{2}

<h3>Solve for y</h3>

-4x-y=2

-y=2+4x

-y=4x+2

\frac{-y}{-1}=\frac{4x+2}{-1}

y=\frac{4x+2}{-1}

y=-4x-2

I need helppppppp plzzzzz
Norma-Jean [14]

Answer:

Step-by-step explanation:

4x + 15 = 3

Subtract 15 from both sides

4x + 15 - 15 = 3 - 15

4x = -12

Divide both sides by 4

4x/4 = -12/4

x = -3

Check:

substitute x = -3 in the LHS of the  equation,

4*(-3) + 15 = -12 + 15

                 = 3 = RHS
