Answer:

1.) X = 7 and Y = 5

2.) 5 streamers

Step-by-step explanation:

According to the question, you are given the inequality equation of

2.5x + 3.5y < = 35

Since the equation is less than or equal to, than means that the equation can be 2.5x + 3.5y = 35

According to the graph,

X = 14 and Y = 10

Substitute both into the equation if it will not exceed 35

2.5(14) + 3.5(10) = 35

35 + 35 = 70. This is wrong.

Take the half value of both x and y and substitute again

X = 7 and Y = 5

2.5(7) + 3.5(5)

17.5 + 17.5 = 35

Therefore, she can buy 7 helium - filled balloons and 5 streamers

2.) If Julie buy 6 ballons, substitute x for 6 in the inequality equation to find y

2.5(6) + 3.5y < = 35

Open the bracket

15 + 3.5y < = 35

Collect the like terms

3.5y <= 35 - 15

3.5y <= 20

Make y the subject of formula

Y <= 20/3.5

Y < = 5.7

We can therefore conclude that she can buy 5 streamers. Or 5 1/2 if possible.

What 5 consecutive odd numbers equal 200
dimulka [17.4K]

Answer:

{36, 38, 40, 42, 44}

Step-by-step explanation:

You are implying that you are adding up 5 consecutive numbers, and should use the word "add" or the word "sum."

"The sum of 5 consecutive odd numbers is 200" leads to:

x + (x+2) + (x+4) + (x+6) + (x+8) = 200.  Note how each number is 2 more than the number preceding it.  In this way you can guarantee that all of the 5 numbers are odd.

Summing up, we get 5x + 20 = 200, or 5x = 180.

Dividing both sides by 5, we get x = 36.

Then the 5 consecutive integers are

{36, 38, 40, 42, 44}.  These add up to 200.

Unfortunately, these are consecutive EVEN numbers, not odd numbers.  

Please ensure that you have copied down this problem correctly.

Anuta_ua [19.1K]

Answer: 41.86 miles/hour

Step-by-step explanation:

Use Distance = Speed*Time to find the two missing values with the data that is provided for those two cases [<em>in brackets</em>].

MPH MILES     HOURS

 50            20      [<em>0.4]</em>

 [<em>40</em>]    <u>70</u>      <u>1.75</u>

Totals   90 miles   2.15 hours

Average = 90 miles/2.15 hours

     41.86 mph
