The answer is B because those triangles are congruent
Two ratios form a proportion if they are equal. If one fraction is equivalent to the other fraction, they form a proportion. To find out, reduce both fractions and see if they are equal.
A
1/2 and 4/2
Reduce 4/2 to 2/1.
1/2 and 2/1 are not equal.
1/2 and 4/2 do not form a proportion.
B
2/1 and 4/8
Reduce 4/8 to 1/2.
2/1 and 1/2 are not equal.
2/1 and 4/8 do not form a proportion
C
1/2 and 8/4
Reduce 8/4 to 2/1.
1/2 and 2/1 are not equal.
1/2 and 8/4 do not form a proportion
D
2/1 and 16/8
Reduce 16/8 to 2/1
2/1 and 2/1 are equal.
2/1 and 16/8 form a proportion.
Answer: D. 2/1 and 16/8
The actual distance between the two towns is 15 miles.
Answer:
B = G + 7 and B + G = 29
Step-by-step explanation:
Let B = boys and G = girls. There are 7 more boys then girls. Set the equation:
B = G + 7
There are 29 students in total. Set the boys and girls equal to the total amount:
B + G = 29
B = G + 7 and B + G = 29 is your answer.

If you would like to know the production rate of factory E, you can calculate this using the following steps:
Factory Number of days Number of shirts
A 2 600
B 3 900
C 4 1200
D 5 1500
Factory E can make shirts at the same rate as the first four factories:
600 shirts / 2 days = 300 shirts per day
900 shirts / 3 days = 300 shirts per day
1200 shirts / 4 days = 300 shirts per day
1500 shirts / 5 days = 300 shirts per day
Factory E will make 1800 shirts in 6 days, therefore 1800 / 6 = 300 shirts per day.
The correct result would be:
Factory Number of days Number of shirts
E 6 1800
