2/3 / 4 = 2/3 / 4/1 During division, the 2nd fraction flips over and the sighn becomes its opposite. division to multiplication.
2/3 * 1/4 =2/12 or 1/6.

Answer:

$\frac{x^4\:-\:2\:x^2\:-\:x\:+\:4}{x\:+\:3}=x^3-3x^2+7x-22+\frac{70}{x+3}$

Step-by-step explanation:

We are going to use long division to find the expression for $\frac{x^4\:-\:2\:x^2\:-\:x\:+\:4}{x\:+\:3}$

Step 1: Divide $\frac{x^4-2x^2-x+4}{x+3}$

Divide the leading coefficients of the numerator $x^4-2x^2-x+4$ and the divisor $x+3$

$\frac{x^4}{x}=x^3$

Quotient = $x^3$

Multiply $x+3$ by $x^3$

$x^4+3x^3$

Subtract $x^4+3x^3$ from $x^4-2x^2-x+4$ to get new remainder

Remainder = $-3x^3-2x^2-x+4$

Therefore,

$\frac{x^4-2x^2-x+4}{x+3}=x^3+\frac{-3x^3-2x^2-x+4}{x+3}$

Step 2: Divide $\frac{-3x^3-2x^2-x+4}{x+3}$

Quotient = $-3x^2$

Remainder = $7x^2-x+4$

Therefore,

$\frac{x^4-2x^2-x+4}{x+3}=x^3-3x^2+\frac{7x^2-x+4}{x+3}$

Step 3: Divide $\frac{7x^2-x+4}{x+3}$

Quotient = $7x$

Remainder = $-22x+4$

Therefore,

$\frac{x^4-2x^2-x+4}{x+3}=x^3-3x^2+7x+\frac{-22x+4}{x+3}$

Step 4:

Quotient = $-22$

Remainder = $70$

Therefore,

$\frac{x^4-2x^2-x+4}{x+3}=x^3-3x^2+7x-22+\frac{70}{x+3}$

A runner is 7/8 mile from the finish line. If she can travel 3/8 mile per minute, how long will it take her to finish the race?

Ksivusya [100]

Answer:

2 1/3 minutes

Step-by-step explanation:

Distance:

d = 7/8 mile

Speed:

s = 3/8 mpm

Time:

t = d/s
t = 7/8 : 3/8 = 7/8 * 8/3 = 7/3 = 2 1/3 min

Destiny designs necklaces she used between 15 and 20 yellow and blue beads in a ratio of 4 yellow beads to 5 blue beads drag the

julia-pushkina [17]

Hey! :)

Well, the ratio of yellow beads to blue beads is 4:5. The best way I think is to guess and check multiplying the ratio by integers. You need between 15 and 20.4 : 5 ( = 9 too little )8 : 10 ( = 18 just right)12 : 15 ( = 27 too much)So per necklace, 8 yellow beads and 10 blue beads would be needed.

Hope this helps! :)
