Answer:

3.5

Step-by-step explanation:

Wright, an equation first like this,

2+8x=30 because he needs 30 dollars but already has 2 and earns 8 dollars per hour.

Solve:

2 + 8x = 30

30-2= 28

28/8= 3.5 so he would need to work 3.5 hours.

Answer:

Alex will need to work 4 hours.

Step-by-step explanation:

We know that Alex already has $2. This means that to get $30 he now only needs to get $28. If he gets $8 per hour, we know that 8 x 3 = 24, but that isn't enough. In this case, 3 is how many hours he works. Because $24 isn't enough, he needs to work 4 hours to get $32 in order to buy the case. Even though he has more money than he needs, he will be able to buy the case and save some extra money.

iren [92.7K]

Based on the distance to the end of the hike and the distance to the scenic lookout, we can calculate that the straight route is 2 km shorter than the scenic lookout route.

<h3>Which route is shorter for Maria?</h3>

If Maria took the straight route to the end of the Hike from the coordinates, (4, -4) to (-5, 5), she would have to walk 13 km.

If she went the scenic lookout route, she would have to first go to (2,3) before going to (-5,5) which is 15 km.

The difference is:

= 15 - 13

= 2 km

A more readable version of the question is:
Maria is on a hike. If she hikes to the scenic lookout on the following map first, she will have to hike farther than if she went straight to the end of the hike.

3 connected points on a coordinate plane. The point labeled, "Maria," is at 4, -4. The point labeled, "end," is at -5, 5.

A solid line connect the points "Maria" and "end." The point labeled, "scenic lookout," is at 2, 3. Dashed lines connect "Maria" to "scenic lookout" and connect "scenic lookout" to "end."

Mr. duc asked to set up 450 chairs in a large hall. Perry puts 20 chairs in each row. He has already set up 15 rows of chairs

Each row consists of 20 chairs

He already set up 15 rows

So number of chairs he already set up = chairs in each row * number of rows

20 * 15 = 300

So , he already set up 300 chairs

Total chairs to set up is 450

Remaining chairs to set up = 450 - 300 = 150

So, 150 more chairs to set up

What is EG? <br><br> I need help
n200080 [17]

Answer:

30

Step-by-step explanation:

y/x = 30/(x + 10)

(y + 12)/x = 54/(x + 10)

y/x + 12/x = 54/(x + 10)

30/(x + 10) + 12/x = 54/(x + 10)

30x + 12(x + 10) = 54x

30x + 12x + 120 = 54x

120 = 12x

x = 10

EG = x + x + 10

EG = 10 + 10 + 10

EG = 30
