last week mrs. kitts sold 6 more than 3 times that the sold this week. she sold over 110 cds over the 2 weeks. which systems of

ladessa [460]

Answer:

The system of equations are:

$y=3x+6\\x+y=110$

CDs sold this week is 26 and that of last week is 84.

Step-by-step explanation:

Let the number of CDs sold this week be $x$ and last week be $y$

Given:

CDs sold last week = 6 more than 3 times she sold this week

∴ $y = 3x+6$ ------------- 1

Also, total number of CDs sold are 110.

∴ $x+y=110$ ------------ 2

Therefore, the above two equations are systems of equations that can be used to find the number of CDs she sold last week and the number of CDs she sold this week.

Now, in order to solve, we plug in the value of $y$ from equation (1) in equation (2). This gives,

$x+(3x+6)=110\\x+3x+6=110\\4x+6=110\\4x=110-6\\4x=104\\x=26$

Now, $y=3x+6=3(26)+6=78+6=84$

Therefore, the number of CDs sold this week is 26 and last week is 84.

Veseljchak [2.6K]

Answer:

domain ( 0-5) minutes

Range ( 0-300) miles

Step-by-step explanation:

Here, we are interested in writing the domain and range for the journey to the prospective colleges.

The range simply deaths with the distances in miles while the domain is the time in seconds.

The range is simply the smallest value on the y-axis to the largest value on the y-axis

The domain refers to the smallest value on the x-axis to the largest value of the x-axis

Kindly note that the domain and range does not refer to the labelings of the highest and lowest value on the axes but the highest and lowest value involved in plotting of the line in the graph.

From the graph, we can see that we have a range of; (0-300) miles while the domain is from (0-5) minutes

PLEASE HELP Evaluate the limit, if it exists. Show work. lim_(x->5)((x^(2)-3x-10)/(2x-10))

gayaneshka [121]

Answer:

$lim \: x \: —>5 \: \: \frac{ {x}^{2} - 3x - 10 }{2x - 10} \\ \\ lim \: x \: —>5 \: \: \: \frac{(x - 5)(x + 2)}{2(x - 5)} \\ \\ lim \: x \: —>5 \: \: \frac{(x + 2)}{2} = \frac{5 + 2}{2} = \frac{7}{2} \\ \\ \\ = \frac{7}{2} = 3.5$

I hope I helped you^_^
