Answer:
C(4)=99.5
Step-by-step explanation:
398 divided by 4 is 99.5
4 is the number of sunglasses and therefore equals x.
So C(4)=99.50
<h2>
Answer: 13 & 19</h2>
<h3>
Step-by-step explanation:</h3>
Let the bigger number be 'U' and the smaller number 't'.
Since the two numbers have a sum of 32, then U + t = 32.
& since one number is 6 more than the other, the U - 6 = t
⇒ U + U - 6 = 32
2U = 38
U = 19
By substituting fot the value of U we found,
19 - 6 = t
t = 13
<h3>∴ the numbers are 13 & 19.</h3>
Answer:
12 dimes, 8 nickels
Step-by-step explanation:
1. Set up an equation. Since we know the relationship between how many dimes and how many nickels that he has, we can create values for them.
2. Say that the number of nickels is x, so the number of dimes would be 2x-4.
3. Since we know that all of the coins that he has is 20 coins, we can say that 2x-4+x=20.
4. Solve the equation. We get 3x=24, and x=8.
5. That means that the number of nickels is 8, and the number of dimes is 2(8)-4, which is 12.
Answer: Timmy has 12 dimes and 8 nickels.
Answer:
The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
Step-by-step explanation:
Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope,
