If the perimeter is 98 cm, the sum of the lengths of two adjacent sides is 49 cm.
... (2x -1) + (3x +5) = 49 . . . . use the given information and relation
... 5x +4 = 49 . . . . . . . . . . . simplify
... 5x = 45 . . . . . . . . . . . . . . . subtract 4
... x = 9 . . . . . . . . . . . . . . . . . divide by 5
The left side dimension is then
... 2x -1 = 2·9 -1 = 17 . . . . cm
The top dimension is
... 3x +5 = 3·9 +5 = 32 . . . . cm
The rectangle is 17 cm by 32 cm.
105 is a composite number. 105 = 1 x 105, 3 x 35, 5 x 21, 7 x 15. Factors of 105: 1, 3, 5, 7, 15, 21, 35, 105. Prime factorization: 105 = 3 x 5 x 7.
Answer:
II. int z;
Step-by-step explanation:
int z;
is the best option, because on the next line you will define the variable as
z = (x + y) / 2;
you can also use int z=0; but it is not necessary according to the code segment given.
Answers:
- 24 mL of oil
- 60 g onions
- 0.36 kg potatoes
- 0.4025 cup of milk
The units for the milk weren't stated, but I'm assuming it's probably "cups".

Explanation:
The recipe makes 16 portions or servings of soup. Richard only wants 4 servings. This means he needs to divide each ingredient amount by 4. Note how 16/4 = 4.
So,
- 96/4 = 24 mL of oil is needed
- 240/4 = 60 grams of onions are needed
- 1.44/4 = 0.36 kilograms of potatoes are needed
- 1.61/4 = 0.4025 cups of milk are needed
Change "cups" to whatever other measurement unit is provided.
