Answer:

x - y = -1 ....... 1

3x + 2y = 22 ........ 2

Make x the subject in the first equation

x = -1+y

Substitute this into the second equation

3(-1+y) + 2y = 22

-3 + 3y + 2y = 22

5y = 25

Divide both sides by 5

y = 5

Substitute y = 5 into x = -1+y

x = -1+5

x = 4

x = 4 , y = 5

Hope this helps

Answer:

x = 10.66 so Daniel can purchase 10 snacks without going over his budget.

Step-by-step explanation:

65 = 4.50x + 17

Subtract 17 from both sides, you're left with 48 = 4.50x

Problem:<br><br> 67.1743<br><br> Round the number above the nearest hundredth.
Musya8 [376]

Answer:

67.17

Step-by-step explanation:

First, identify the hundreds digit (the 7)

Next, identify the next smallest place value (the 1)

Then, determine if 7 greater than or equal to 1. Yes, it is greater than 1, so round up. Increase the hundreds digit by one, so 7 becomes 8.

Finally, keep .17 and you get an answer of 67.17.

What is the smallest 3-digit number of the form aaa such that it is divisible by 9? (Here, a represents a digit.)
polet [3.4K]

Answer:

If all three digits need to be the same (I assume that's what aaa means) it's 333

Step-by-step explanation:

For a number XYZ to be divisible by 9, X+Y+Z must be divisible by 9. Here's why:

X*100 + Y * 10 + Z = X + Y + Z + 99*X + 9*Y = X + Y + Z + 9(11X + Y)

So we need to find the smallest a so that a+a+a = 3a is divisible by 9. The smallest would be 0, but 000 is not a real 3-digit number. The next one is 3.

Answer if correct only but please help!!
djyliett [7]

According to above statement the required Inequality will be :

  • 31 + 5.6t < 75.8

  • 5.6t < 75.8 - 31

  • 5.6t < 44.8

  • t <  \dfrac{44.8}{5.6}

  • t < 8

hence, the value of t should be less than 8 hours.

so, they can rent the meeting room for 7 hours.
