Answer:
3, 4, 5
Step-by-step explanation:
so, we need to find all integers for which
23 <= 7x + 2 <= 37
=>
21 <= 7x <= 35
3 <= x <= 5
so, that is correct for x = 3, x = 4 and x = 5.
Answer:
Step-by-step explanation:
(-7-41)(8-6)
-48*2
-96
This is what I got. I don't see anything in the equation that has "i" in it.
If it is supposed to be (-7-4i)(8-6) foil the problem.
-56+42-32i+24i combine like terms
the answer is -14-8i
<span>Let x represent the number of pairs of socks purchased,
and let y represent the number of blouses purchased.
</span><span>socks that cost $2.99 for each pair
and blouses that cost $12.99 each
equation
2.99x + 12.99y = 43.92</span>
<span>Let the number of hours she works be x
2x+15 15 more than twice the
3x-15 15 less than 3 times the hours she worked
2x+15=3x-15
3x-2x= 30
x= 30
the number of hours she worked is 30
