Answer:
33 children
62 adults
Step-by-step explanation:
Set up 2 equations (a=adults c=children)
The first equation will be 3.25(a)+3 = 300.5
The second equation will be a + c = 95
Subtract c from both sides to get:
a = 95 - c
Replace c in the 1st equation to get:
3.25(95-c) + 3c = 300.5
Distribute 3.25 to 95 and -c:
308.75 - 3.25c + 3c = 300.5
Subtract 308.75 from both sides:
-3.25c + 3c = 300.5 - 308.75
Combine like terms:
-0.25c = -8.25
Divide by -0.25
children = 33
Subtract 33 from 95 to get
adults = 62
Answer:
The answer is - sample.
Step-by-step explanation:
Based on the set of 356 surveys that were completed and returned, the researcher finds that these students spend an average of 3.1 hours each day watching television.
For this study, the set of 356 students who returned the surveys is an example of a SAMPLE.
A sample is defined as a small part that shows what the whole population is like.
Answer:
Table 4 represents the same linear expression as y = 3 x - 2.
Step-by-step explanation:
Here, the given expression is y = 3 x -2
So now check the any random pair of each table by putting in the given equation.
<u>TABLE 1 : (2,-5)</u>
y = 3x -2 ⇒ -5 = 3(2) -2
or, -5 = -4 , NOT POSSIBLE
<u>TABLE 2 : (0,3)</u>
y = 3x -2 ⇒ 3 = 3(0) -2
or, 3 = -2 , NOT POSSIBLE
<u>TABLE 3 : (1,2)</u>
y = 3x -2 ⇒ 2 = 3(1) -2
or, 2 = 1 , NOT POSSIBLE
<u>TABLE 4 : (1,1)</u>
y = 3x -2 ⇒ 1 = 3(1) -2
or, 1 = 1 , POSSIBLE
checking for (2,4)
4 = 3(2) - 2 ⇒4 = 4 POSSIBLE
Here, table 4 satisfies the given points in the expression y = 3x -2
Hence, it represents the same linear expression .
Answer:
r ≥ -1. it is A because r is greater than or equal to -1.
I am sorry <u>if</u> I got it wrong.
Step-by-step explanation:
3r+2(12r+7) ≤ 5r-8
27r+14 ≤ 5r-8
I subtract 27r and 5r.
22r+14 ≤ -8
I subtract 14 and -8.
22r ≤ -22
Divide 22 on both side.
r ≥ -1
