Answer:
2.86$
Step-by-step explanation:
first you must find out how much she is spending since she is buying 2.8 pounds of asparagus that are 2.55 per pound you can just times 2.8 x 2.55 its the same as if it were a dollar for a pound it would be 1 x 1 except in the case of this question it is a decimal number. Now that you know how much she spent you would subtract it from 10 since that's the amount she gave the cashier so you subtract the cost from how much she gave and you will get how much change she will get.

Answer: It is <u>
not</u>
a solution</h3>
======================================================
Explanation:
Plug in w = -2 and simplify.
3w ≤ -12
3(-2) ≤ -12
-6 ≤ -12
The last inequality is false because -6 is neither equal to -12, nor is -6 smaller than -12. Use a vertical number line to see that -6 is above -12, so it should be -12 ≤ -6.
Since -6 ≤ -12 is false, that makes 3w ≤ -12 false when w = -2.
Therefore, w = -2 is <u>not</u> a solution to the given inequality.

Step-by-step explanation:
Answer: x = -3 y = 2 So (-3,2)
Step-by-step explanation:
- x + 3y = 9 Multiply everything by 2 then add to the second equation.
2x + 5y = 4
<u>-2x +6y =18 </u> then 2x-2x=0 Add the other terms and solve for y.
11y = 22 divide both sides by 11 yo get y = 2 Substitute that into either one and solve for x.
2x + 5y = 4
2x + 5(2) = 4
2x + 10 = 4 subtract 10 from both sides 2x = 4 -10
2x = -6 so divide both sides by 2 to get x = -3
