Answer:
2nd option: 3a-11≤7
Step-by-step explanation:
Step 1: The inequality on the number line is:
Step 2: Take a look at the options. First we know that we want values of a which are less than 6 so we get rid of option 1 and 3.
Step 3: Since 6 is included in the inequality so we need to have a ≤ so 2nd option is correct.
<em>QUICK </em><em>NOTE:</em><em> </em>if we solve the inequality shown in the 2nd option we'll see it's gonna be a≤6
take a look:
Answer:
93 pieces
Step-by-step explanation:
To cover his backyard with sod, he needs to cover the area of the backyard.
His backyard is a rectangle, and area of a rectangle is given as:
Where,
is the length, and
is the width
So, the area of Jim's backyard is square yards.
The area of each sods are solved using the area of the rectangle formula. So we have square yards as the area of each sod.
<em>To find </em><em>HOW MANY</em><em> of these sods we would need to cover the whole backyard, we divide the backyard area by each sod area:</em>
<em></em>
<u>Since, fractional sods can't be bought, Jim has to buy </u><u>93 sods</u><u> to cover his backyard.</u>
