y=2x-3
y=x+2 system of equations

Answers

Answer:

x = 5

y = 7

Step-by-step explanation:

Since they are both equal to y, we can set them equal to each other.

2x - 3 = x + 2

Combine like terms and isolate the x.

x = 5

Plug in the x to either equation to get the value of y.

y = (5) + 2

y = 7

Answers

Answer:

True

Step-by-step explanation:

it is 3/5. Than 6/10 is equal to 3/5. Than 9/15 is equal to 3/5.

Answer: True

Step-by-step explanation:

That is true because let's take the first point for example.

3 cups of almonds for 5 cups of oats.

3/5 of 5 is 3

So that's correct.

If you still aren't sure you should try that with a different point. Hmm how about :

9 cups of almonds for 15 cups of oats

3/5 of 15 = 45/5 = 9

That's correct as well.

If 8 engines consume 12000 kgs. of coal when each running 10
hours per day, how much coal is required for 7 engines out
which 5 are running 12 hours a day and the rest 6 hours a day?​

Answers

Answer:

11200 for 7 engines for a total of 80 hours

Step-by-step explanation:

You have 8 engines burning 12000 .for 10 hours.

Divide 10 hours into 12000=1200 PER hour.

1200 ÷8 engines = 140 per hour per engine.

140 × # of hours (12)=1680 for 12 hours per engine.

# of engines × 1680 for 12 hour/per engine

5×1680 = 8400 of fuel for 12 hours/5 engine

Then you have 2 that runs 10 hours

2 × 140 per hour per engine =280 × 10 =2800 for 2 engines for 10 hours

8400. + 2800= 11200 of fuel for 6 engines

She sniffled and used a handkerchief to wipe away her tears. Taking a deep breath, she rapped on the door of the world's most famous detective.Mrs. Hudson answered the door and ushered the visitor to Sherlock Holmes' flat. The detective stood tall and confident, gazing at Mrs. Blakely with an inquisitive smile. He invited Mrs. Blakely to enter. Mrs. Hudson offered her some tea. After using the tea to warm her hands, Mrs. Blakely felt capable of explaining her situation. Yesterday afternoon, Mrs. Blakely had arrived home to find a masked individual robbing her house. When the mysterious figure heard her approach, he or she ran farther into the house and disappeared. All that remained was the black mask lying on the ground. Mrs. Blakely's most prized possession, a massive purple gem, also had disappeared. While Mrs. Blakely knew it would be useless to ask Holmes to retrieve the gem, she wanted him to determine how the thief and gem had disappeared so completely.Sherlock Holmes listened to the tale and agreed to visit the crime scene. The safe was open and empty, but it was not damaged. There was no visible entry into the room where the safe was kept: the windows were sealed, and the door was not damaged. Mrs. Blakely led Sherlock Holmes farther into the house and stopped in the middle of a hallway of old portraits. There were no windows, and the only door was at the other end of the hallway."This spot is where I found the black mask," Mrs. Blakely explained.Sherlock Holmes inspected the hallway with a wrinkled brow. He walked up and down the hallway. He put his hand on the smooth floor. Then, Sherlock's brow smoothed and a glint entered his eyes. Turning to the wall, he pressed the expensive portrait into the wall."What are you doing to my painting?" Mrs. Blakely gasped."Calm down, Mrs. Blakely," Holmes replied. "The solution to this mystery is staring you in the face. There is no sign of a break in, so the thief has access to the house. The thief disappeared in this spot without using the far door, so there must be a hiding spot within the walls or floor. There are scratches on the ground near this portrait. I felt a draft when I reached down to test the floor. It's elementary, Mrs. Blakely. The thief is hidden in the wall behind this portrait."Holmes pushed the portrait harder into the wall. The wall moved, revealing a hiding place. Sherlock Holmes lit a candle. Its light revealed a sleeping maid with a gigantic purple gem clasped in her hands. The mystery of the disappearing thief was solved.Select the detail that supports this statement: Mrs. Blakely was upset when she arrived to speak with Sherlock Holmes.
