6.4x + 2.8y = 44.4 

6.4(3) + 2.8y = 44.4

19.2 + 2.8y = 44.4

Answer:

when x=3 the value of y is 9

Step-by-step explanation:

6.4x+2.8y=44.4, when x=3

6.4x+2.8y=44.4

To find y when x=3, plug in 3 for x in the given equation

6.4x+2.8y=44.4

6.4(3)+2.8y=44.4

19.2+2.8y=44.4

Subtract 19.2 on both sides

2.8y=25.2

Divide both sides by 2.8

y=9

So when x=3 the value of y is 9

The following frequency table shows the number of fish caught by each of Igor's family members. What was the maximum number of f
Tcecarenko [31]

Answer:

4

Step-by-step explanation:

The values on the left of the table represent the number of fish caught, and the number of the right of the table represents how many family members caught that amount of fish.

Therefore, the first row means that 0 family members caught 0 fish.

The second row means that 3 family members caught 1 fish.

The third row would mean 1 family member caught 2 fish.

The next row would mean 0 family members caught 3 fish.

And the final row would mean 4 family members caught 4 fish.

The question does not ask for the total amount of fish caught; rather is ask for the maximum number of fish that a single family member caught.

Therefore, the maximum amount of fish that a single family member catches is 4. (And 4 family members did so. But individually, the maximum amount of fish one person caught is 4).

iris [78.8K]

for the first term:

n= 1 there is 1 item

n=2 there are 2+1 = 3 items

n = 3 there are 3+2+1 = 3+2 = 6 items

n = 4 there are 4+3+2+1 = 4+6 = 10 items

We are adding the "n" term each time

n = 5 10+5 = 15

n= 6 15+6 = 21

n = 7 21+7 = 28

n = 8 28+8 = 36

There would be 36 items in the 8th step
