The colony of penguins travel 3/5 of a kilometer a day. how many kilometers will they travel in a week.

4 1/5

Step-by-step explanation:

(2*3 is the same as 2x3 in multiplication)

Since in a week there are 7 days, you multiply the number of days to the distance walked per day. Which is 7*(3/5), or (3/5)*7

So (3/5)*7=4 1/5 or 4.2

(3/5)*7 equals

(3/5)+(3/5)+(3/5)+(3/5)+(3/5)+(3/5)+(3/5)=(21/5)

There are four 5's in 21, so it is 4 wholes.

4 an the remaining 1 over 5

=4 1/5

javeir earned 56 dollors more than kyle so kyle and javier had 14w but javier made 56 dollors more so 14w plus 56 equals 70w so kyle has 14w

step-by-step explanation: hope i plz give me brainliest with the points so this is not constant cause it says last week so its clearly not every week

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
