Answer:
The correct answer is 72 + 4 × x 
400.
Step-by-step explanation:
The dance committee of Pine Bluff Middle School earns $72 from a bake sale and will earn $4 for each ticket they sell to the Spring Fling dance.
The dance will cost $400.
Let x number of tickets the committee could sell.
Total money earned is 72 + 4 × x.
The committee should have some left over money also after spending for the dance which costs $400.
Thus the inequality to determine the number of tickets the committee could sell to have money left over after they pay for this year's dance is given by,
72 + 4 × x 400.
<span>The five digit number, 55,220 contains to 5's and two 2's. The 5's are in the ten thousand and one thousand columns. This means that one five represents 50,000 and the second represents 5, 000. The two's are in the hundreds and tens columns meaning one 2 represents 200 and the other 2 represents 20. In a direct comparison of these numbers the 5's equal 55,000 and the 2's equal 220</span>
Answer:
-56c+ 30
Step-by-step explanation:
4c + 10(3 – 6c)
Rearrange terms
4c + 10(3 – 6c)
4c+10(-6c+3)
Distribute
4c+10(-6c+3)
4c-60c+30
Combine like terms
4c-60c+30
-56c+30
Common factor
-2(28c-15)
Distribute
-2(28c-15)
-56c+30
Solution:
-56c+30
Step One is to add up all the values
6.5+5+6+5.5+7+4+4.5+5+6+5.5+4+7.5+6+7+8+5+6+6.5+6.5+5 = 116.5
Step Two is to divide the result from step one by 20 (since there are 20 values added up)
116.5/20 = 5.825
The sample mean is 5.825
B is the correct answer.....
