Answer:
Step-by-step explanation:
This is a compound inequality that basically states that the X value is greater than or equal to -5, but less than or equal to -1. It is inclusive, because it includes both numbers and therefore should have an equal to sign (
) instead of just less than or greater than ( < or >).

Step-by-step explanation:
<h3>The better deal would be the the 5kg for $14 price.</h3><h3 /><h3>Why: 5kg is around 11 pounds, so if you bought the 11 pounds on the first site, it would be $24.75. So Lisa would save 10 dollars if she chose the second site.</h3><h3 /><h3>If this answer is correct, please mark it as Brainliest. :)</h3>
This breaks down into a system of equations. George will equal G, Sam will equal S and Alex will equal A. G=S+2 S=A+3 G+S+A=35 since S=A+3, we can substitute S for (A+3). If we plug that into the G=S+2, we get G=(A+3)+2. This simplifies to G=A+5.
our ultimate goal is to be able to substitute for two of their ages so we can solve the last equation for one age or variable. It would be easiest to solve for A.
so far we can substitute for two variables, S=A+3. and G=A+5
Next, we can plug this into the last equation and get 35=(A+3)+(A+5)+A
if we add like terms we get 35=3A+8. Next, we solve the equation by first subtracting 8 from each side. we then get 27=3A, then we divide each side by 3 to solve for A and get A=9.
Now we have one age, we need to find the other two. We can solve this by plugging A to the other two equations. if we do that we get S=(9)+3, or S=12. If we do it to the other equation we get G=(9)+5, or G=14
So your final answer would be George is 14, Sam is 12, and Alex is 9.
Step-by-step explanation:
|y – 3| − 4 ≤ −3
|y – 3| ≤ -3+4
|y – 3| ≤ 1
-1 ≤ y-3 ≤ 1
=> -1 ≤ y - 3 or y - 3 ≤ 1 (the first option)
