Answer:

x = 20

Step-by-step explanation:

The three angles make up a straight line.

A straight line has 180 degrees.

x + 3x + 100 = x80          Combine

4x  +  100 = 180               Subtract 100 from both sides

4x = 180 - 100

4x  = 80                           Divide by 4

x = 80/4

x = 20

Aaron bought 8 red flags for the parade. Large flags cost $20 each. Medium flags cost $12 each. Aaron spent $112 in all. How man
andrew11 [14]

Answer:

Step-by-step explanation:

Price assuming he bought all large flags: 20*8=160

Amount of money more: 160-112=48

Difference of price in both flags: 20-12=8

Medium Flags: 48\div8=6

Large Flags: 8-6=2

----------------------------------

The reason why this works, is because the amount of money more comes from the difference between both flags.

Answer:

The value that will create an equation with no solutions is 5x.

Step-by-step explanation:

No solution would mean that there is no answer to the equation. It is impossible for the equation to be  true no matter what value we assign to the variable.

To create a no solution equation, we can need to create a mathematical statement that is always false.  To do this, we need the variables on both sides of the equation to cancel each other out and have the remaining  values to not be equal.

Use distributive property on the left side first.

3(x - 4) = [blank] - 2x +7\\\\3x-12=5x - 2x +7\\\\3x-12=3x+7\\\\3x-12+12=3x+7+12\\\\3x=3x+19\\\\3x-3x=3x+19-3x\\\\0=19

Notice that we combined like terms first and then eliminated the variable from one side. When that  happened, the variable on the other side was eliminated as well, giving us a false result.

Since zero does not equal nineteen, we know we have an equation with no solution.
