The value placed in the box that makes the system of equation with infinitely many solution is 12.

<h3>How to solve an infinitely many solution equation?</h3>

An infinite solution has both sides equal. For example, 6x + 2y - 8 = 12x +4y - 16. If we simplify the equation we will notice both sides are equal. This means the equation has an infinitely many solution.

Hence,

y = -2x + 4

Therefore,

6x + 3y = 12

divide the equation(ii) by 3

2x + y = 4

y = -2x + 4

Therefore, both equation are equal if the the box is filled with 12. This means for the value placed in the box that makes the system of equation with infinitely many solution is 12.

Infinite solutions ig without one or more actual number or variable there is no way to get one solid answer. (Im not positive ik im probably very wrong but this is just my guess by looking at it Im barely passing math as is)

cd city sells 5 cds for 49$ music land sells 8 cds for $59.50 which store is the better place to buy cds

Dmitriy789 [7]

Answer:

Music land has the better deal with each CD costing only $7.44 compared to $9.80 at CD City.

Step-by-step explanation:

In order to find the price per CD, you must divide the cost by the number of CDs in the bundle.

<u>Music Land</u>

$59.50/8 CDs = $7.44 per CD

$49/5 CDs = $9.80 per CD

Therefore, we know that Music Land is a better deal.

Another path in the community is 2.1 miles long. It has benches at 1/3 And 2/3 of the distance from beginning to end of the path

emmasim [6.3K]

Answer:

bench at 1/3 is at 0.7 miles

bench at 2/3 is at 1.4 miles

Step-by-step explanation:

Given

Path length, x= 2.1 miles

It has benches at 1/3 And 2/3 of the distance from beginning to end of the path

1/3 of the distance from beginning to end of the path= 1/3x

Putting value of x in above we get:

=1/3(2.1)

=2.1/3

=0.7

The bench at 1/3 of the distance is at 0.7 miles from the beginning to end of path

2/3 of the distance from beginning to end of the path= 2/3x

Putting value of x in above we get:

=2(2.1)/3

=4.2/3

=1.4

The bench at 2/3 of the distance is at 1.4 miles from the beginning to end of path!

A fair coin is tossed four times, and each time the coin lands heads up. if the coin is then tossed 1996 more times, how many he

andrey2020 [161]

Answer:

998 heads are likely to appear

Step-by-step explanation:

When a fair coin is tossed, the probability to flip a head is 50% and to flip a tail is also 50%, so if the coin is tossed 1996 times, 0.5*1996 = 998 heads and 998 tails are likely to appear, despite the fact the coin lands heads up 4 times before, because every toss is independent of the other ones.
