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

Write an equation in slope intercept format that has a slope of 1/5 and includes the point (10, 7).
Write your answer as y=mx+b. Write your answer as a fraction if it is not an integer. (#/#)
If I'm understanding the question,
Answer: y = (1/5)x + 5
Answer:
y = 1/5 x +5
Step-by-step explanation:
Substitute the values of y and x from the given coordinate and solve for b.
7 = 1/5(10) + b
7= 2 + b
7-2 =b
5 = b

Kate is going to the fair with three of her friends. It will cost $5.00 to get in and an additional $2 per ride. Create an equation to represent the cost for the whole group and then use the distributive property to expand the expression and solve the problem.
Expression: (4*5)+(2*5)=30
So I have the expression I just need to do the distributive property and I don't understand how to do that.
Answer:
5 * ( 4 + 2 ) = 5 * 6 = 30
Step-by-step explanation:
(5*4) + (2*5) = 20 + 10 = 30
5*4 = 4 people need to pay $5
2*5 = $2 for 5 rides
Distributive Property:
(5*4) + (2*5) = 5 * ( 4 + 2 )
5 * ( 4 + 2 ) = 5 * 6 = 30
Answer:
$40Step-by-step explanation:
Ok, so the distributive property allows us to apply a number evenly over a whole set of numbers.
Equation: 4 (2 x 5) (we distribute the 4 to all terms, since each person experiences those charges.) The answer is $40 for the whole group.
