Answer: Total number of pairs =872
Step-by-step explanation:
Since we have given that
Number of pairs of skates during the month of April =218
Number of pairs of skates during the month of May =3 × 218=654
As we know that total means altogether in which we perform the additive operation.
Total pairs of skates the skating rent during April and May = 218+654=872
∴ Total number of pairs =872
Step-by-step explanation:
Distribute into 5x² into (3x +2).
The simplified expression is <em>15x³ + 10x²</em>
The correct answer is C as it has the same line of equation. We can make this clear by verifying that these two points make the same equation or not. So as we can see if we calculate the gradient using the formula y2 - y1 / x2 - x1.
As we now know that the gradient is -1. We can simply put any one point in the equation y - y1 = m(x - x1) to get the line of equation. WHen we calculate the line of equation it come out to be y = -x + 7
The greatest common factor of the expressions 60x and 84 is 12 because it can divide both 60 and 84 giving us the answer of 5 and 7, respectively. Factoring out 12 from the terms of the given expression will give us the answer of,
60x - 84 = 12(5x - 7)
Answer:
x= 20 and y= 12
Step-by-step explanation:
nickel is 5 cents and quarter is 25 cents,
let x be number of nickels and y be number of cents
x+y = 32
5x + 25y = 400
you get x= 20 and y= 12
x - 
D) y = -3x + 9
