2. Solve the following system of equations. y = 5 + x 2x + 2y = 30
larisa86 [58]
X = 5

since we know y= 5 + x , plug this into y in the second equation.

2x + 2 (5 + x) = 30

distribute 2 into the 5 and x

2x + 10 + 2x = 30

combine like terms

4x + 10 = 30

subtract 10 from both sides

4x = 20

divide four by both sides to isolate the variable

x = 5

The data set shows the year's coldest temperatures (in degrees Fahrenheit) for a few cities. Which value would be the best measu
Alisiya [41]

<u>Answer:</u>

The correct answer option is  C. 24.

<u>Step-by-step explanation:</u>

We are given the following data set:

12, 14, 16, 20, 20, 22, 24, 26, 26, 26, 30, 30, 32

These are 13 values in the data set and we are to find the best measure of center for this data, which is also called the mean.

Since, the number of values is odd, we can use the following formula to find the central value for this data:

\frac{n+1}{2} where n is the number of values

\frac{13+1}{2} = \frac{14}{2} = 7

Therefore, the 7th value in the data set is the best measure of center which is 24.

erma4kov [3.2K]

Answer:

Explained below.

Step-by-step explanation:

First of all, an integer is a whole number that can be either positive, negative or zero.

Now, a drop in temperature signifies a reduction in the temperature.

This means that if for example, the current temperature is 50 °C, a drop in temperature of 10°C would mean that the current temperature would be gotten by subtracting 10 from 50.

Now,current temperature after drop would be;

T = 50 - 10

To prove that it is gotten by adding a negative integer:

This can also be written as;

T = 50 + (-10)

Because from mathematical multiplication signs, minus multiplied by plus gives minus.

Since, T = 50 + (-10), it means that a negative integer of minus 10 has been added to the initial temperature to get the new decreased temperature.
