Solve equation k/0.32=2.2
Mandarinka [93]
Hey there Shynee!
To do this equation, you have to flip the equation and do it on both sides.
k/0.32 = 2.2
Instead of division, multiply on both sides.
k/0.32 * 0.32 = 2.2 * 0.32
This isolates the variable
k = 0.704
and finds what x equals.

Check:
0.704/0.32 = 2.2
Correct.

I hope I helped!

8+35/w=15<br>a.8<br>b.6<br>c.10<br>d.5​
RoseWind [281]

Answer:

\boxed{ \bold{ \huge{ \bold{w = 5}}}}

Option D is the correct option

Step-by-step explanation:

\sf{8 +  \frac{35}{w}  = 15}

⇒\sf{ \frac{8 \times w + 35}{w}  = 15} { w ÷ 1 = w , So, I wrote 8 × w }

⇒\sf{ \frac{8w + 35}{w}  = 15}

Apply cross product property

⇒\sf{8w + 35 = 15w}

Move 15w to left hand side and change it's sign

Similarly, Move 35 to right hand side and change it's sign

⇒\sf{8w - 15w  =  - 35}

Collect like terms

⇒\sf{ - 7 w =  - 35 }

Divide both sides of the equation by -7

⇒\sf{ \frac{ - 7w}{ - 7}  =  \frac{ - 35}{ - 7} }

Calculate

⇒\sf{w = 5}

Hope I helped!

Best regards!!
