Answer:

x = 80

Step-by-step explanation:

Combine − 3/5x and 7/20x to get -19/20x.

Then combine -19/20x and 1/4x and you get -7/10x.

Then you multiply both sides by -10/7 which is the reciprocal of -7/10.

Make -56(-10) one fraction.

Multiply -56 and -10 and you get 560.

Then divide 560 by 7 to get 80.

For a number to be divisible by 6, it must also be divisible by 2 and 3. Therefore, we need to check if a number is even and then check if the sum of the digits is divisible by 3.

Answer:

Question 3: $b \geq 2$

Question 4: $r < -5$

Question 5: $y \leq -6$

Step-by-step explanation:

Question 3:

$b + 2 \geq 4\\b + 2 -2 \geq 4 - 2\\b \geq 2\\$

Question 4:

$13 > 18 + r\\13 - 18 > 18 -18 + r\\\\-5 > r\\ r < -5$ sign flips when r switches sides

Question 5:

$3y \leq 2y - 6\\3y - 2y \leq 2y - 2y - 6\\\\y \leq - 6\\$
