Answer: 6 m

This statement:

"Jared has run two-thirds of an 18-kilometer race" can be written as an equation:

18km.\frac{2}{3}=12km

This means two-thirds of 18 km is equivalent to 12 km

If we substract this value to the total, we have the values of the kilometers left to run:

18km-12km=6km

Therefore the correct option is D

Two mechanics worked on a car. The first mechanic worked for 10 hours, and the second mechanic worked for 5 hours. Together they
Anvisha [2.4K]
You would first make an equation to show their individual price per hour multiplied by hours worked then added together to equal total cost. let X be mechanic 1 and Y be mechanic 2

10x + 5y = 1225

the second equation will use their price per hour added together to equal combined cost per hour

x + y = 180

you would solve by substitution. to do so, isolate either x or y in the second equation. for convenience, I will isolate x

x = 180 - y

plug in (180 - y) for x in the first equation

10(180-y) + 5y = 1225

1800 - 10y + 5y = 1225

-5y = -578

y = 115.6

this means that the second mechanic charges $115.60 per hour

to find the price per hour for the first mechanic, plug in (115.6) for y in the second equation

x + 115.6 = 180
x = 64.4

the first mechanic charges $64.40 an hour

Aaron wants to make a path to guide guest through the conservation area.He uses rolls of rope to make the path.He uses 3/4 of a
mel-nik [20]

Answer:

Aaron needs <u>2 more rolls</u> to complete the path.

Step-by-step explanation:

Given:

Total rolls Aaron has = 4

Part of path covered by using \frac{3}{4} of a roll = \frac{1}{8}

So, in order to find the number of rolls required to cover the complete path is given using the unitary method.

Rolls used for \frac{1}{8} of a path = \frac{3}{4}

Therefore, rolls used to cover the whole path is given by dividing the rolls used for one-eighth of the path and the path covered. This gives,

=\frac{3}{4}\div \frac{1}{8}

=\frac{3}{4}\times \frac{8}{1}

=\frac{3\times 8}{4\times 1}

=\frac{24}{4}

=6\ rolls

Now, rolls required to complete the path is 6. But Aaron has only 4 rolls.

So, he will need 6 - 4 = 2 rolls more to complete the path.

exis [7]

Answer:

seven nineteen


Step-by-step explanation:

This is because the small hand represents the hour, and it's on 7. So the hour is 7:--. Then the next thing you do is check the big hand, the big hand represents the minutes, the minute hand is just before 20 so it's nineteen. The answer is the big hand 7: + the :19 so this makes 7:19 :D
