Answer:
x > -1
Step-by-step explanation:
<u>Step 1: Distribute</u>
3(3x + 7) > 4 - 8(4 + 5x)
(3 * 3x) + (3 * 7) > 4 + (-8 * 4) + (-8 * 5x)
9x + 21 > 4 - 32 - 40x
<u>Step 2: Combine like terms</u>
9x + 21 > 4 - 32 - 40x
9x + 21 > -28 - 40x
<u>Step 3: Add 40x to both sides</u>
9x + 21 + 40x > -28 - 40x + 40x
49x + 21 > -28
<u>Step 4: Subtract 21 from both sides</u>
49x + 21 - 21 > -28 - 21
49x > -49
<u>Step 5: Divide both sides by 49</u>
49x / 49 > -49 / 49
<em>x > -1</em>
Answer: x > -1
Ok, since the minutes here are 30, all we need to do is simply add 25 minutes to our time.
3:30
Now 30 + 25= 55
So our final time he finished: 3:55
The incorrect claim is A. He is incorrect. The path will have an area of (4)(40)=160 sq ft. The yard has an area of 600 sq ft. The area of the lawn will be the difference of the yard and path, so it is 440 sq ft.
<h3>What is an Area?</h3>
This refers to the quantity used in mathematics to show the extent of a two-dimensional region, shape, or planar lamina, in the plane.
Hence, because Roy wants to make a path from one corner of his yard to the other, he makes an incorrect claim about the area of the yard and the lawn, and option A is the correct answer.
