Answer:
x = 2/3
y = -13/15
Step-by-step explanation:
3x – 8 = -6
+8 +8
[addition property of equality]
3x = 2
÷3 ÷3
[division property of equality]
x = 2/3 → -2x – 5y = 3
[substitution property]
-2(2/3) – 5y = 3
[distributive property]
-4/3 – 5y = 3
[Create the proportional equivalent of each term so that all terms share the same denominator]
-4/3 – 15y/3 = 9/3
[multiplication property of equality]
3 ( -4/3 – 15y/3 ) = 3 ( 9/3 )
[distributive property]
-4 – 15y = 9
+4 +4
[addition property of equality]
-15y = 13
÷-15 ÷-15
[division property of equality]
y = -13/15
Find the area of the shaded region.
Answer:
103.62
Step-by-step explanation:
a = πr^2
Area large circle
a = π7²
a = π(49)
a = 153.86
Area inner circle
a = π4²
a = 50.24
Area shaded = large cicle - inner circle
a = 153.86 - 50.24
a = 103.62

Step-by-step explanation:
Consider the following statement: Two sets of data with the same mean will also have the same variability. Do you agree or disagree with this statement? Explain.
The statement is false and same mean can have different variability
What is Mean?The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
Let the mean of the data be represented as M
Now , The mean is a measure of central tendency that represents the average value of a set of data, but it does not provide information about the variability or spread of the data.
For example, consider the following two sets of data:
Set 1: 1, 2, 3, 4, 5 (mean = 3)
Set 2: 0, 2, 3, 4, 6 (mean = 3)
Both sets have the same mean of 3, but Set 1 has a smaller range (4) compared to Set 2 (6). The range is a measure of variability that represents the difference between the maximum and minimum values in a set of data.
Hence , two sets of data with the same mean can have different variability,

Zachary traveled from city A to city B. He left city A at 7:30 a.m. and reached city B at 12 noon. Find his average speed if city B is 180 mi away from city A.
Please include the units after the answer!
Answer:
40 mph
Step-by-step explanation:
s = d/t
a to b's distance = 180 miles
7:30 - 12pm = 4.5 hours (time)
speed = 180 ÷ 4.5
speed = 40
Plz answer :) will be marked BRAINLIEST!
Answer:
65 mph
Step-by-step explanation:
To find the unit rate (miles per hour), we can use the equation
[tex]r=\frac{d}{t}[/tex]
Where
r=rate (miles per hour)
d=distance (in miles)
t=time (in hours)
Using the given information, we can plug in
[tex]d=97\frac{1}{2}[/tex]
[tex]t=\frac{3}{2}[/tex]
So, our equation is
[tex]r=\frac{97.5}{1.5}[/tex]
When we divide 97.5 and 1.5, we get
[tex]65[/tex]
So,
[tex]r=65[/tex]
In conclusion, the rate (miles per hour) is 65 mph.

The volume of the baseball is about ____ in3.
Answer:
Volume is about 26.5 in^3
Step-by-step explanation:
The volume = 4/3 pi r^3 where r = the radius.
the radius = 1/2 diameter = 1/2 * 3.7 = 1.85 ins.
So V = 4/3 * 3.14 * 1.85^3
= 26.5084
