Answer:
40-5x
Step-by-step explanation:
Sahai starts with 40 and loses 5 times the entrance fee, which is represented by x. So, 40-5x is the expression
Total Marbles = 6 + 3 + 2 = 11
Total Red marbles = 6
P(red) = 6/11
Equation 1: x² + y = 7
Equation 2: 3x + 7 = 9
Use Equation 2 to solve for "x" and plug in "x" into Equation 1 to solve for "y".
3x + 7 = 9
3x = 2
x =
*********************************
x² + y = 7
()² + y = 7
+ y = 7
y = 7 -
y = -
y =
Answer: (, )
Answer:
<em>The number of race entries must be at least 1800.</em>
Step-by-step explanation:
Suppose, the number of race entries is
It receives $75 per race entry. So, the total amount received from the race entries
It also receives $10000 in donations. So, <u>the total amount received</u>
Now, it must spend $25 per race entry to cover the cost of the race. So, <u>the total amount spend</u> for all race entries
Given that, the charity needs to raise at least $100,000. So, the inequality will be........
So, the number of race entries must be at least 1800.
Answer:
A series can be represented in a compact form, called summation or sigma notation. The Greek capital letter, ∑ , is used to represent the sum. The series 4+8+12+16+20+24 can be expressed as 6∑n=14n . The expression is read as the sum of 4n as n goes from 1 to 6 .
