For coordinate pairs, you write the x-coordinate first, then the y-coordinate second.

Just like how x comes before y in the alphabet!

Hence, since the x-coordinate is 10 and the y-coordinate is 8, the answer is (10,8).

Ryan and Sarah collect baseball cards. Ryan has 150 baseball cards and collects 10 cards per week. Sarah has 233 baseball cards

ICE Princess25 [194]

Answer:

About 17 weeks

Step-by-step explanation:

Given

Ryan:

$Initial = 150$

$Additional = 10$ (weekly)

Sarah:

$Initial = 233$

$Additional = 5$ (weekly)

Required

Determine the number of weeks they have the same cards

Represent the number of weeks with w:

For Both individuals, number of card at any given week is:

$Initial + Additional * w$

So,

For Ryan, the expression is:

$150 + 10 * w$

$150 + 10w$

For Sarah, the expression is:

$233 + 5 * w$

$233 + 5 w$

To determine the number of weeks, we have to equate both equations:

$150 + 10w= 233 + 5 w$

Collect Like Terms

$10w - 5w = 233 - 150$

$5w = 83$

Solve for w

$w = 83/5$

$w = 16.6$

16.6 implies about 17 weeks, because 16.6 approximates to 17

Conclusively, Ryan and Sarah will have the same number of balls in about 17 weeks

If y varies directly as x and z and y=4 when x=6 and z=1 find y when x=7 and z=4

yawa3891 [41]

Answer-

The value of y is $\dfrac{56}{3}$ when x=7 and z=4.

Solution-

As given in the question, y is directly proportional to x, so

$y\propto x$ -----------------1

And also y is directly proportional to z, so

$y\propto z$ -----------------2

Combining equation 1 and 2,

$\Rightarrow y\propto x.z$

$\Rightarrow y=k.x.z$

Where,

k = proportionality constant

When x=6 and z=1, y=4. Putting theses values,

$\Rightarrow 4=k\times 6\times 1$

$\Rightarrow 4=6k$

$\Rightarrow k=\dfrac{4}{6}$

$\Rightarrow k=\dfrac{2}{3}$

Now, we have to find the value of y, when x=7 and z=4

$\Rightarrow y=\dfrac{2}{3}\times 7\times 4$

$\Rightarrow y=\dfrac{56}{3}$

Therefore, the value of y is $\dfrac{56}{3}$ when x=7 and z=4.

Answer:

1 1/8

Step-by-step explanation:

19 7/8-18 3/4

change the 3/4 to 6/8 so they the same denominator then subtract:

19 7/8 - 18 6/8= 1 1/8 inches
