Answer:
81
Step-by-step explanation:
Let's do this systematically:
Four numbers: a, b, c, d
Whose mean is 85: 
Whose largest number is 97: 
Lets solve for the other numbers:
a+b+c+97 = 85*4 = 340
340 - 97 = 243
a+b+c = 243
at this point it doesn't matter what the numbers are, they just need to add up to 243.
We can do 243÷3=81, which is our answer
Answer:
77bb
Step-by-step explanation:
The answer to your question is option a
Mean means the average so you plus all the scores and divide that by the number of scores and when to undo that, the answer you get is a
The equation representing the cost of 6 chairs and a table is:
6x + x + 50 = 750
⇒
7x = 700
This equation is true for x = 100 because:
7(100) = 700
So, the cost of one chair will be $100.
Cost of table is $50 more than a chair, so the cost of one table is $150.
So the answers are:
$ 100
$ 100
$ 150
Answer:
67667.7
Step-by-step explanation:
let the number= Y
the question simply means that 0.15 percent of Y which give 10.5
so, let find Y:
0.15% of Y 10.15
<h3>Stating the mathematical equation</h3>
0.15/100×y = 10.15
0.0015y= 10.15
divide bothsides by 0.0015
0.0015y/0.0015= 10.15/0.0015
y=6766.66
y= 6766.7 approximately
<h3>therefore, 0.15% of 6766.7 is 10.5</h3>
