Answer:
-1 + w ≤ 4
Step-by-step explanation:
w is greater than -1 = -1 + w
Less than or equal to 4 = (anything less than or equal to 4)≤4
(28) 2x+10+x-4=21
(29) 3x-16+4x-8=60
(30) 2x-8+3x-10=17
1/3 = 10/30
2/5 = 12/30
1/6 = 5/30
sum of all of them = 27/30
the fraction that chose the lime sublime is 1/10
Ok so the answer is

so we multiply numbers that have the same variable

multiply 2 x 2

then multiply the exponents

multipling like this will look like addition.

so in other words you could do it like this too

now add the exponent with 4

now for the last part

because -3 and 3 added together make 0

I hope this help(it looks complicated but it's very easy and I hope I helped you out)
250 = 5 x is the equation you can use
