Sari applied the distributive property using the greatest common factor to determine the expression that is equivalent to 84 +40. Her work is shown below.
Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40
84 + 40 = 2 (42 + 20)
What statement best describes Sari’s error?
Sari did not use correct factors for 84 in the equation.
Sari did not use correct factors for 40 in the equation.
Sari did not use two equivalent expressions in the equation.
Sari did not use the greatest common factor in the equation.
Answer: Sari did not it’s the greatest common factor in the equation
Step-by-step explanation: the GCF is 4 because it’s the highest number they have in common

1. A 100-point test has x questions worth 2 points apiece and y questions worth 4 points apiece.
a. Write an equation that describes all possible numbers of questions that may be on the test.
b. If you have 24 questions worth 4 points apiece, how many questions will be worth 2 points apiece?
Answer:
a. 2x+4y=100
b. 2 questions
Step-by-step explanation:
For a, you can write out hat equation, which can test if a specific combination will work, and once you have one variable, you can solve another
For b, you can plug 24 into the equation
2x+4(24)=100
2x+96=100
2x=4
x=2

Your friend incorrectly claims that 1/5 divided by 1/10 = 1/50. Find 1/5 divided by 1/10. Then describe what may have been your friend’s error.
Answer:
1/5 divided by 1/10 is 15. The friend's error was that they did not keep, change, and flip. They did 1 divided by 1 which equals 1, and then 5 divided by 10 which equals 50. This is what gave them 1/50.
There were 18 seeds planted in the garden. After one week there were 324 seedlings. After 2 weeks there were 648 seedlings. If the number of seedlings grows at the same rate each week, how many seedlings will there be after 5 weeks?
Answer:
The answer is 1620 seedlings.
Step-by-step explanation:
The rate is that every one week, there is an increase of 324 seedlings. If it continued for 5 weeks, the total amount of seedlings will be 1620 seedlings. The equations I used to solve this are 648-324=324. 324x5=1620.
