Answer:
Carrots cost $ 1.75 a pound which is more than potatoes cost.
Step-by-step explanation:
Let,
Carrots cost $ x per pound and potatoes cost $ y per pound.
Buying 2 pounds of carrots and 3 pounds of potatoes will cost her

$ 
According to the question,
-----(1)
-----(2)
multiplying (1) by 2 we get,
-----(3)
Deducting (2) from (3) we get,
⇒ 
------------------(4)
Putting value of y in (1) we get,
⇒ 
------------(5)
5.3×10^5=53×10^4
53×10^4+3.8×10^4
=56.8×10^4
=5.68×10^5. Hope it help!

Step-by-step explanation:
<u>Step 1: Define equation</u>
4x - 1 = 7x - 16
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 4x on both sides: -1 = 3x - 16
- Add 16 to both sides: 15 = 3x
- Divide 3 on both sides: 5 = x
- Rewrite: x = 5
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 4(5) - 1 = 7(5) - 16
- Multiply: 20 - 1 = 35 - 16
- Subtract: 19 = 19
Here we see that 19 does indeed equal 19.
∴ x = 5 is a solution to the equation.
- 6 - (-2)
- (-2) = 2
* two negatives = one positive
-6 + 2 = -4
-4 is your answer
hope this helps
