Cal/oz, because the unit rate has to convert back to calories.

We want to find the cal/oz, since that is the unit rate.

666 ÷ 6 = 111 calories per 1 ounce

The unit rate is 111 ca/1 oz. (Chose ca/oz)

Part A: Find the LCM of 7 and 12. Show your work. (3 points)

inna [77]

Answer:

A. 84; B. 8; C. 8 × 19

Step-by-step explanation:

Part A. Least common multiple

Step 1. List the prime factors of each.

7 = 7

12 = 2 × 2 × 3

Step 2: Multiply each factor the greatest number of times it occurs in either number.

7 has one 7; 12 has two 2s and one 3.

LCM = 7 × 2 × 2 × 3

LCM = 7 × 12

LCM = 84

Part B. Highest common factor

Find all the factors of 56 and 96.

Factors of 56: 1, 2, 4, 7, 8, 14, 28

Factors of 96: 1, 2, 4, 6, 8, 12, 16, 24, 32, 48

The highest factor that in both 56 and 96 is 8.

Part C. Factoring

56 + 96 = 8(7 + 12) = 8 × 19

The GCF is 8.

19 = 7 + 12 is the sum of two numbers that do not have a common factor.

astraxan [27]

Red = r

Blue = b

Green = g

Step 1: Write as algebraic equations.

r = b + 6

g = b - 4

Step 2: Merge the two equations together to form one, by adding them together.

r + g = b + b + 6 - 4

Step 3: Simplify.

r + g = 2b + 2

Step 4: Make b the subject.

2b + 2 = r + g

2b = r + g - 2

b = 0.5(r + g - 2)

ANSWER

b = 0.5(r + g - 2)
