Answer:
-786
Explanation:
Move 4^-4 to the numerator using the negative exponent rule 1/x^-n = x^n
<em>-(3×^4)</em>
Raise 4 to the power of 4.
<em>-(3×256)</em>
Multiply 3 by 256.
<em>-1×768</em>
Multiply -1 by 768.
<em>-768</em>
This is because you can at most, factor out x² and y³
Answer:
3 dogs and 2 cats.
Step-by-step explanation:
In this case we can solve it using a 2x2 system of equations, like this:
let x: number of cats
let y: number of dogs
So:
42.5 * x + 64 * y = 277
35.5 * x + 50.5 * y = 222.5 => x = (222.5 - 50.5 * y) /35.5
Replacing, we are left with that:
42.5 * (222.5 - 50.5 * y) /35.5 + 64 * y = 277
266.37- 60.45 * y + 64 * y = 277
64 * y - 60.45 * y = 277 - 266.37
3.55 * y = 10.63
y = 10.63 / 3.55
y = 2.99, about 3
Now to calculate x:
x = (222.5 - 50.5 * 3) /35.5
x = 2
Which means that it has a total of 3 dogs and 2 cats.
Front yard
65+65+45+45=220
Back yard
45+45+35+35=160
220+160=380
380 feet
7*60 = 420
810/420 = 1.9285
93- 100 = 53-60
subtract 40 from 93.
1.53*8 = 12.24
Answer: 12 hours and 24 Minutes
