tomas wrote an equation 4/5x-8=. Finish the equation so that the equation will have no solution. Explain how you know.

Pepsi [2]

Answer:

Right part: $\dfrac{4}{5}x+a,$ where $a\neq -8.$

Step-by-step explanation:

Linear equation have no solution if it is impossible for the equation to be true no matter what value we assign to the variable x.

The left part of the equation Tomas wrote is

$\dfrac{4}{5}x-8.$

The right part of the equation should be of the form

$\dfrac{4}{5}x+a,$

where $a\neq -8.$

In this case, the equation will take look

$\dfrac{4}{5}x-8=\dfrac{4}{5}x+a,\\ \\-8=a.$

Since $a\neq -8,$ this equality is always false.

Remark: 1) If a=8, the equation $\dfrac{4}{5}x-8=\dfrac{4}{5}x+a$ is equivalent to the equation

$\dfrac{4}{5}x-8=\dfrac{4}{5}x-8,\\ \\0=0$

and the lest equation has infinitely many solutions.

2) When coefficient at x differs from $\dfrac{4}{5},$ the equation has unique solution.

Together, Steve and Tom sold 104 raffle tickets for their school. Steve sold 17 more than twice as many raffle tickets as Tom. H

Svetllana [295]

Tom = x
steve = 2x + 17

x + 2x + 17 would then simplify to 3x + 17

104 = 3x + 17
87 = 3x
29 = x

then substitute x into tom and steve

steve = 75 tickets
tom = 29 tickets

PLZ HELP!! WILL GIVE BRAINLIEST!! PLZ ANSWER HONESTLY TYSM!! The distance, y, in miles, traveled by a car for a certain amount o

nevsk [136]

Answer:

D. It travels for 2 hours, then stops for 1 hour, and finally travels again for 2 hours.

Step-by-step explanation:

From the pair (0, 0) to (2, 26), we can see over a period of two hours, the car moved 26 miles, as the distance went from 0 to 26.

From the pair (2, 26) to (3, 26), we can see over the course of an hour, the car maintained the same distance, 26 miles, the entire time. This means that it stopped. We can rule out options A and B since those include a stop of 3 hours, when the stop is actually only 1.

From the pair (3, 26) to (5, 52), we can see over a time period of 2 hours, the car moved from 26 to 52 miles, so in other words it travelled. We can rule out C because the car only travelled 2 hours, from hour 3 to hour 5.

This leaves us with D as the answer, which perfectly fits the graph.
