The one on the left!

Closed dot means that the number is being included. So if you have 6, the 6 would be included as an answer. An open dot means that it isn't included!

A large bag of cashews weighs 9 1/4 pounds. One serving is 1/5 pound. How many servings are in the bag.
Ann [662]

Answer as a mixed number = 46 & 1/4

Answer as a decimal = 46.25

===============================================

Work Shown:

9 & 1/4 = 9 + 1/4 = 9 + 0.25 = 9.25

1/5 = 0.2

A bag of cashews weighs 9.25 pounds and one serving is 0.2 pounds.

Let x be the number of servings

1 serving = 0.2 pounds

x servings = 0.2x pounds after multiplying both sides by x

0.2x pounds represents the total bag's weight so,

0.2x = 9.25

x = 9.25/0.2

x = 46.25 answer in decimal form

x = 46 + 0.25

x = 46 + 1/4

x = 46 & 1/4  answer in mixed number form

This means we have 46 full servings plus an additional 1/4 of a serving.

Write and solve an equation to find the values of d and w .
NNADVOKAT [17]

Answer:

d = 65°

w = 55°

Step-by-step explanation:

m∠DAC +∠m∠CAB = 60

m∠DAC + 35 = 60

m∠DAC = 25

m∠DAC + d = 90

25 + d = 90

d = 65°

m∠GAF + w + d = 180

60 + w + 65 = 180

w + 125 = 180

w = 55°
