Answer:
Answer (C) ⇒ He replaced the wrong term with its reciprocal in step 2
Answer (A) ⇒ How many 3/8 's in 48
Step-by-step explanation:
∵ The distance = 25 miles
∵ The time = 2/3 hour
∵ Average speed = distance ÷ time
∴ Average speed = 25 ÷ 2/3 ⇒ step 1 (he is √)
= 25 × 3/2 ⇒ step 2 (his 1st error 1/25 × 2/3)
= 75/2 miles/h
∵ How many 3/8 's are in 48 means:
48 ÷ 3/8 = 48 × 8/3 = 128
∴ Answer (A) is best modeled with a division expression
Answer:
x=27
Step-by-step explanation:
180-2x-40+180-3x+180-x-50+180-4x = 360
360-2x-40-3x+360-x-50-4x= 360
360-10x-90= 0
10x= 270
x= 27
Answer:
a line that might best estimate the data and be used for predicting values.
Choice B is correct
Step-by-step explanation:
A line of fit might be defined as;
a line that might best estimate the data and be used for predicting values.
This line connects most of the data points thus minimizing the squared residuals of the regression.
I hope this helps...
So, there are 12 pieces. since he ate 1/4 of it already, he divided the rest to 1/12 each equivlent to a whole pizza. since 1/6 of it was left, so, he got 1/4 for himself, each friend had one, then 1/6 was left. before, he made it equivlent to a twelve piece minus 4. 12 - 4 = 8, 1/6 means 6 pieces or 3 for 12. final answer, it would most likely be 6 or 4. thank you.
