Question1: What is the sum of −3x+6 and 7x−8? *

Question2: What is the sum of −5x−3 and −2x+9? *

1. -3x+6+7x-8= 4x-2

2. -5x-3-2x+9=-7x+6

Step-by-step explanation:

For number one and two , Add/subtract the numbers with the same symbol, such as -3x + 7x and -5x - 2x

Then add/subtract 6-8  and -3+9 to get the answer

hope I

could help!!

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
