Step-by-step explanation:
<u>Step 1: Define</u>
35 + 0.8x = 43 - 7x
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Addition Property of Equality] Add 7x on both sides: 35 + 7.8x = 43
- [Subtraction Property of Equality] Subtract 35 on both sides: 7.8x = 8
- [Division Property of Equality] Divide 7.8 on both sides: x = 1.02564
1 yard = 3 feet, so 2yds x 1yd is the same as 6ft x 3ft, or 18 square feet
If one acre contains 43,560 square feet, and the question asks how many trees can be planted per acre, then all we have to do is divide 43,560 by 18:
43,560 ÷ 18 = 2420 trees
So, the answer is A) 2,420.
Y is less than or equal to 3.
The filled dot means or equal.
The line to the left of the number line is less.
Answer:
I can’t post an image, but I’ll explain below
Step-by-step explanation:
Start at a point where the line crosses through a coordinate exactly, like (0,1), and find a second one. Draw a line from the first to the right until it’s over the second point, then go down to the second point. It should look like half of a rectangle. Just follow the lines of the graph :)
