If u work it out and both sides don't equal, then there is no solution.
Example :
2x + 4 = 2x + 6
2x - 2x = 6 - 4
0 = 2....this is incorrect...therefore, there is no solution

A quadratic equation can have no real solution
aa x^{2} +bx+c=0
If b^{2} -4ac\ \textless \ 0 then the equation has no real solutions
Even simultaneous equations can have no solutions
ax+by=c------1
ax+by=d------2
I these two equations the two expressions equal different things, so the equation has no solutions

Think of it as two rectangular prisms next to each other, and find the volume of each one separately.

The big one on the left has a volume of 4 * 12 * 6, or 288.

The smaller one on the right has a volume of 2 * 6 * 6, or 72.

288 + 72 = 360. 360 cubic feet of water are needed.

Original price: $150; Markdown:40%(show work please)
zepelin [54]
Original price is $150 so you times 150 by 0.40
150 x 0.40 = 60
So you take the $150 and you subtract $60 from $150
150 - 60 = 90
So the answer is $90

3. Calvin has a bucket of marbles. The table shows the number of marbles of each color Color Amount Red Blue 3 Yellow 4 Green Ca
dalvyx [7]

The false statement is (c) the probability of selecting a blue or yellow marble is less than the probability of selecting a red or green marble.

<h3>What are probabilities?</h3>

Probabilities are used to determine the chances of events

The table entry is given as:

  • Red  - 2
  • Blue - 3
  • Yellow  - 4
  • Green - 3

From the list of options, the false statement is

(c) the probability of selecting a blue or yellow marble is less than the probability of selecting a red or green marble.

This is so because:

  • Blue or Yellow = 3 + 4 = 7
  • Red or Green = 2 + 3 = 5

Notice the count of blue or yellow marbles (7) is greater than the number of  red or green marbles (5)

This means that, the probability of selecting a blue or yellow marble is greater than the probability of selecting a red or green marble.
