This morning, Tammy's car had 15.03 gallons of fuel. Now, 4.9 gallons are left. How much fuel did Tammy use?

10.13

Step-by-step explanation:

15.03-4.9=10.13

10.13 gallons

Step-by-step explanation:

Here, you want to use subtraction

15.03-4.9

4.9 is that same as 4.90

So if we use a subtraction table...

15.03

04.90 -

10.13

This works because I have taken away a digit from the 2nd colum

(Where the 5 was) and I replaced it with a 4 (which isn't shown in my workings). This digit I took away I put next to the 0 in the 3rd colum so I could successfully take away way 10 from 9.

Although the answer is 10.13, remember to state the gallons! So the proper answer should be 10.13 gallons!

Hope this helps!

(c, 0) i might be wrong so don't put full faith on my answer

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
