Answer:

1 2/3 : 4 3/8 = 8

≅ 0.3809524

Step-by-step explanation:

Conversion a mixed number to a improper fraction: 1 2/3 = 1 · 3 + 2

= 5

Conversion a mixed number to a improper fraction: 4 3/8 = 4 · 8 + 3

= 35

Divide: 5

: 35

= 5

· 8

= 5 · 8

3 · 35

= 40

105

= 8

To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.

A rectangle has a perimeter of `52` cm. Its width is `9` cm.

aniked [119]

The length will be 17.
Perimeter equation is L+L+W+W= Perimeter

9+9+W+W=Perimeter

I took 18 and subtracted it from 52 and got 34.

Since we are calculating one side length I divided by 2 which got me to 17.

4x-11y=68 ; 6x+5y=-27 by elimination

zimovet [89]

Answer:

$x=\frac{1}{2}\\\\y=-6$

Step-by-step explanation:

Given the following system of equations:

$\left \{ {{4x-11y=68} \atop {6x+5y=-27}} \right.$

In order to solve the system of equations using the Elimination Method, you can follow these steps:

- Multiply the first equation by -6 and the secondd equation by 4.

- Add both equations.

- Solve for "y".

Then:

$\left \{ {{-24x+66y=-408} \atop {24x+20y=-108}} \right\\.........................\\86y=300\\\\y=\frac{-516}{86}\\\\y=-6$

- Substitute the value of "y" into one of the original equations and solve for "x":

$6x+5(-6)=-27\\\\6x=-27+30\\\\x=\frac{3}{6}\\\\x=\frac{1}{2}$
