E =<br> =<br> 5e + 3f = -36<br> -e + 2f = 2<br> f = 1

Ann [662]

Answer:

e = -6

f = -2

Step-by-step explanation:

I used the elimination method and multiplied the second equation by 5 to get:

-5e + 10f = 10. Added this to:

+ 5e + 3f = -36

13f = -26

f = -2

now find e: -e - 4 = 2

-e = 6

e = -6

Answer:

$11 \frac{1}{4}$ = $\frac{45}{4}$ = $11.25$

Step-by-step explanation:

Hi!

Next time, I'd recommend just typing in the number, this is a bit hard to see.

To the point!

11 $\frac{1}{4}$ is equivalent to $\frac{45}{4}$ and in decimal form is 11.25.

Hope this helps!
