Find two numbers if their sum is 7.2 and their difference is 2.7

Klio2033 [76]

Answer:

4.95 and 2.25

Step-by-step explanation:

x+y=7.2

x-y=2.7

Add equations

x+y + x-y= (2x-y+y)=2x

7.2+2.7=9.9

Therefore 2x=9.9 x=9.9/2=4.95

x=4.95

x+y=7.2

4.95+y=7.2

y=7.2-4.95=2.25

y=2.25

Yellowstone National Park is a popular field trip destination. This year the senior class at High School A and the senior class

Rina8888 [55]

Each van carries 13 students and each bus carries 25 students.

<h3><u>Distribution</u></h3>

Given that the senior class at High School A and the senior class at High School B both planned trips to Yellowstone, and the senior class at High School A rented and filled 5 vans and 2 buses with 115 students, while High School B rented and filled 1 van and 6 buses with 163 students, and each van carried the same number of students and each bus carried the same number of students, to determine the number of students in each van and in each bus, the following calculation must be made:

5X + 2Y = 115
1X + 6Y = 163
5X + 2Y = 115
5X + 30Y = 815
815 - 115 = 28Y
700 = 28Y
Y = 700 / 28
y = 25
1X + 6x25 = 163
1X = 163 - 150
X = 13

Therefore, each van carries 13 students and each bus carries 25 students.

Fiber One Bran Cereal boasts that it contains 57% of the Daily value of fiber you need. If 1 serving contains 14 grams of fiber,

Makovka662 [10]

The amount of fiber needed in a day is 7.98 grams

<h3>Proportions</h3>

Proportions are parts, in comparative relation to a whole.

In other words, proportions are fractions of a larger dataset

The given parameters from the question are given as:

Proportion of the daily value of fiber needed = 57%
Daily serving = 14 grams.

<h3>Amount of fiber</h3>

The amount of fiber needed in a day is the product of the proportion and the size of the daily serving.

So, we have:

$Amount = 57\% \times 14g$

$Amount = 7.98g$

Hence, the amount of fiber needed in a day is 7.98 grams
