Answer:

It will be 60 pixels high and 75 pixels wide

Step-by-step explanation:

$\frac{400}{60}=\frac{500}{x}$

The space allowed for the mascot on a school's Web page is 75 pixels wide by 60 pixels high
Its digital image is 500 pixels wide by 400 pixels high

So, the expression becomes

$\frac{400}{60}=\frac{500}{x}$

$\mathrm{Apply\:fraction\:cross\:multiply:\:if\:}\frac{a}{b}=\frac{c}{d}\mathrm{\:then\:}a\cdot \:d=b\cdot \:c$

$400x=60\cdot \:500$

$400x=30000$

$\mathrm{Divide\:both\:sides\:by\:}400$

$\frac{400x}{400}=\frac{30000}{400}$

$\mathrm{Simplify}$

$x=75$

Therefore, it will be 60 pixels high and 75 pixels wide

What’s is x=5y for y

Margarita [4]

Answer:

$y=\frac{x}{5}$

Step-by-step explanation:

$\frac{x = 5y}{5}$

For the y to cancel out, you would have to divide y by 5. Whenever you do one thing to a side, you have to do the same on the other side. Once you do so, you'll get : $\frac{x}{5}$

Hope this helps!!
