Answer: 18 degrees

Step-by-step explanation:

To get the mean add up all of the values that you are given and divided it by how many there are.

Week One:

The values added up to 364 I then divided 364 by 7 to get a mean value of 52.

Week Two:

The values added up to 490, I then divided 490 by 7 to get a mean value of 70.

(In the above problems, I divided by 7 because there are 7 temperatures given)

I then subtracted 70 and 52 and got 18 degrees greater during week two.

find the consecutive even integers such that three times the larger number is 30 more than the smaller one. help :')
Minchanka [31]

Answer:

12 and 14

Step-by-step explanation:

Let the even integers be x and x+2

three times the larger number is expressed as 3(x+2)

30 more than the smaller one is x + 30

Equating both expressions

3(x+2) = x +30

Find x

3x+6 = x+30

3x-x = 30-6

2x = 24

x = 12

The second integer is 12+2 = 14

Hence the required integers are 12 and 14

madam [21]

Answer:

The total for the housewife's purchase should be 60 dollars. So it should be the vender who owes her money. The vender owes her 15 dollars.

Step-by-step explanation:

$5 = 1kg (eddoes) meaning a total of 2kg eddos =$10

$10 = 1kg (chicken) meaning a total of 5kg chicken = $50

When added together, it'd be 60 dollars.
