To find three consecutive odd integers that have a sum of 63

2 answers:

8 0

Since we are finding the sum of three consecutive odd integers, we will be skipping our even numbers so we can set up an equation.

X + X + 2 + X + 4 = 63

Now, since we have 3 X's on the same side, we can combine them. We can also combine 4 and 2 together to get 6.

<h2>3x + 6 = 63</h2><h2> -6 -6 ← subtract 6 on both sides</h2><h2 /><h2 /><h2>3x = 57</h2><h2>÷3 ÷3</h2><h2 /><h2>X = 19</h2><h2>X + 2 = 21</h2><h2>X + 4 = 23</h2><h2 /><h3>Therefore, our three consecutive odd integers are 19, 21, and 23.</h3>

If the angle measure of the section for giraffes is 72∘, how many students said giraffes were their favorite zoo animal?

laiz [17]

Answer:

12 students

Step-by-step explanation:

Here is the complete question

Alex surveyed 60 students about their favorite zoo animals and made the circle graph of the results shown below. A circle graph titled Favorite Zoo Animals is shown. There are five sections. One section is labeled Bears, one section is labled Lions, one section is labeled Monkeys, one section is labeled Elephants, and one section is labeled Giraffes.

If the angle measure of the section for giraffes is 72∘, how many students said giraffes were their favorite zoo animal?

Number of students that said the giraffe was their favorite zoo animal = (angle measuring the section for giraffes / sum of angles in a circle graph) x number of students surveyed

the sum of angles in a circle = 360 degrees

(72 / 360) x 60 = 12 students

A discount airline sells a certain number of tickets, x, for a flight for $90 each. It sells the number of remaining tickets, y,

yKpoI14uk [10]

Answer:

x+y= 120

90x+250y=27,600

Step-by-step explanation:

x= number of certain tickets

y= number of remaining tickets

The statement indicates that for a particular flight the airline sold 120 tickets which means that the sum of the different tickets is 120. The first equation is:

x+y= 120

Then, the statement says that certain number of tickets costs $90 and the remaining tickets cost $250 and that for a particular flight, the airline collected $27,600. From this, you can say that the number of certain tickets, x, multiply for its price that is $90 plus the number of the remaining tickets, y, multiply for its price that is $250 would be equal to $27,600. The equation would be:

90x+250y=27,600

According to this, the answer is that the system of equations that represents this relationship between x and y is:

x+y= 120

90x+250y=27,600
