A boat travels from a port and moves 12 miles north and then moves 5 miles east. what is the present distance of the boat from the port?

Answers

Answer 1

Answer: What helped me find the answer if I am correct would be that I drew a number line to represent the distance the boat is moving from the port. The first thing I did was I drew an arrow pointing to the right all the was to the number 12 and then I drew another arrow pointing to the left to show that the boat moved 5 miles to the east and the the question asked now how many miles is the boat from the port so the answer would be 7 miles. P.s. Sorry this is soooo long.

Answers

2 centiliters = 2 * 10 milliliters = 20 milliliters.

1 centiliter = 1 * 10 milliliter = 10 milliliter

always when moving from centiliters to milliliters, you multiply by 10.

so he took 20 milliliters.

Write 6y = x + 5 in standard form using integers. A. –x + 6y = 5
B. –6x + 6y = 30
C. -6x - 6y = 30
D. 6x - 6y = 30

Answers

I hope this helps you

-x+6y=5

Standard form is Ax+By=C, so with that knowledge, we can work with the problem to get it how we want it!

Our first step is to get x and y on the same side of the equals sign. To do that, we can subtract an x from both sides, turning 6y = x + 5 into -x +6y = 5. Lucky for us, this brings us straight to the answer, which is A) -x +6y = 5!

Two arcades have different pricing structures. Arcade A costs $5 to enter and $0.60 per game. Arcade B costs $7 to enter and $0.40 per game. How many games do you have to play in order for the two arcades to be the same price?

Answers

Answer:

you would have to play 10 games

Answer:

10 games

Step-by-step explanation:

Let C be cost and x be number of games

Arcade A: C = 5 + 0.6x

Arcade B: C = 7 + 0.4x

for both arcades to be the same price, Both C's must be equal, hence we equate the right side of both equations:

5 + 0.6x = 7 + 0.4x (subtract 5 fromboth sides)

0.6x = 7 + 0.4x - 5

0.6x = 2 + 0.4x (subtract 0.4x from both sides)

0.6x - 0.4x = 2

0.2x = 2 (divide both sides by 0.2)

x = 2 / (0.2)

x = 10

A road crew must repave a road that is 3/5 miles long. They can repave 1/15 miles each hour. How long will it take the crew to repave the road?

Answers

The Total number of hours required to repave the whole road is 36.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

The Total length of the road that needs to be repaved = 3/5 miles

The Total length of the road which is repaved by the road crew per hour = 3/5 miles

The Total number of hours required to repave the whole road

= (Length of the road to be repaved)/(Length of the road repaved by the crew per hour)

= 3/4 divided by 1/48

= 3/4*48/1= 144/4

= 36

Hence, The Total number of hours required to repave the whole road is 36.
