Add 6x+20+4x+7x-10=180

Combine like terms 6x+4x+7x= 17x 20-10=10

17x+10= 180 180-10= 170 170/17x= 10

So x = 10

A cafeteria can feed 1/8 of the school in 3 1/2 minutes. How long does it take to feed the school?
77julia77 [94]

Answer:

28 minutes

3.5 x 8 = 28

Step-by-step explanation:

Feeding the whole school (8/8) would take 8 times as long as feeding 1/8 of the school.

3 1/2 can become 3.5 if that's easier for you to work with.

Feeding 1/8 of the school is 3.5 x 1 = 3.5

Feeding 2/8 of the school is 3.5 x 2 = 7

Feeding 8/8 of the school is 3.5 x 8 = 28

It takes 28 minutes to feed the whole school (8/8)

Which of the following correlation coefficients represents the strongest
erik [133]

Answer:

\boxed {\boxed {\sf -0.92}}

Step-by-step explanation:

A correlation coefficient is a number ranging from -1 and 1 that measures the strength and direction of a linear relationship.

  • If it is a negative number, the linear relationship is also negative. If it's positive, the relationship is positive.
  • The closer it is to -1 or 1, the stronger the relationship.

Since the question only asks for the strongest relationship and does not ask for the direction (positive/negative), we can simply choose the number closest to -1/1. Therefore, the answer is -0.92.
