Clare knows that Priya has a bunch of nickels and dimes in her pocket and that

enyata [817]

Answer:

a) 21 nickels and 2 dimes

b) $5x+10y=125$

c) There are 13 nickels and 6 dimes

d) The point (13,6) a solution to the equation you wrote

Step-by-step explanation:

Let x be the number of nickels and y be the number of dimes in Priya's pocket.

1 nickel = 5 cents

x nickels = 5x cents

1 dime = 10 cents

y dimes = 10y cents

b. Total amount in nickels and dimes is $5x+10y$ cents that is $1.25. Convert $1.25 into cents:

$\$1.25=125\ cents,$

so the equation that describes the relationship between the number of dimes and number of nickels is

$5x+10y=125$

a. To find one possible solution, substitute an arbitrary value of y and find x. Let y = 2, then

$5x+10\cdot 2=125\\ \\5x+20=125\\ \\5x=125-20\\ \\5x=105\\ \\x=21$

21 nickels and 2 dimes

c. The point (13,6) means that there are 13 nickels and 6 dimes.

d. Substitute x = 13 and y = 6 intoe the equation and check whether it is true:

$5\cdot 13+6\cdot 10=65+60=125$

True, so the point (13,6) a solution to the equation you wrote

A spinner with nine equal-sized sections numbered one to nine is spun once. What is the probability that the spinner will land o

Umm I'm not sure on this but a regular probability is 1/9 so maybe taking out the 3 would leave 6/9 or in other word 2/3

RST has vertices R(0,0), S(10,5), and T(5,-5). R’S’T’ is the image of RST after a dilation with center (0,0) and scale factor 1/

AysviL [449]

The coordinates of the point S' is (2,1)

Explanation:

Given that the RST has vertices R(0,0), S(10,5) and T(5,-5)

The image R'S'T' is the image of RST after a dilation with center (0,0) and scale factor $\frac{1}{5}$

We need to determine the coordinates of the point S'

The coordinates of S' can be determined by multiplying both the x and y - coordinates of the point S with the scale factor $\frac{1}{5}$

Let us consider the x - coordinate of the point S and multiply it with the scale factor $\frac{1}{5}$

Thus, we have,

x - coordinate of the point S' is given by

$10 \times \frac{1}{5}=2$

Thus, the x - coordinate of the point S' is 2

Similarly, the y - coordinate of the point S' can be determined by multiplying the point S with the scale factor $\frac{1}{5}$

Thus, we have,

The y - coordinate of the point S' is given by

$5\times\frac{1}{5}=1$

Thus, the y - coordinate of the point S' is 1

Hence, the coordinates of the point S' is (2,1)
