Elvis is trying to get fit for a Marathon. He wants to run 45km. Each week. This week he has runs of 7.5km,10.25,6.4km 12.8 km. How many more Kilometers does he need to run to reach his goal for the week

8.05 km

Step-by-step explanation:

just add everything together then subtract by 45

7.5+10.25+6.4+12.8=36.95 45-36.95=8.05

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

the answer is d. (1.2, -4.7) on edgn

hope this !
