Answer:
Naomi must buy a minimum of 5 blocks of cream cheese.
Explanation:
2.75 pounds = 44 ounces
44 oz divided by 8 oz (per block) =
5.5 blocks of cream cheese
She already has 4 oz of cream cheese so subtract 1/2 block of cream cheese.
She needs to buy at least 5 blocks.

Step-by-step explanation:
the appropriate null and alternative hypotheses's are something
Answers: Angle A is 36 degrees, angle C is 54 degrees
=================================================================
Work Shown:
The angles A and C are complementary, meaning they add to 90 degrees.
(Angle A) + (Angle C) = 90
(2x-4) + (2x+14) = 90
(2x+2x)+(-4+14) = 90
4x+10 = 90
4x+10-10 = 90-10 .... subtract 10 from both sides
4x = 80
4x/4 = 80/4 ..... divide both sides by 4
x = 20
If x = 20, then,
angle A = 2x-4 = 2*20-4 = 40-4 = 36 degrees
angle C = 2x+14 = 2*20+14 = 40+14 = 54 degrees
Note how A+C = 36+54 = 90 which helps confirm our answers.
