Step-by-step explanation:
So 5k-7=-7
You need to do the opposite of addition,which is subtraction so...
5k-7=-7
+7
__
K=0
and to double check it,replace the (or variable) with our answer (0)...
so
5×0-7=-7
solve the problem...and
-7=-7√
Step-by-step explanation:
Annie: 4 dollars = $4 11 dimes = 11 x 0.10 = $1.1 ( since 1 dime = 0.10 dollars)
4 pennies =4 x 0.01= $0.04 ( since 1 penny = 0.01 dollars)
Tommy 3 dimes = 3 x 0.10 = $0.3 3 pennies = 3x 0.01 = $0.03
Adding the values: 4 +1.1+0.04+0.3+0.03 = $5.47
If you subtract 1.1 from 5.8 you will end up with 4.7
then you subtract 10^7 from 10^8 which will give you 10^1
then you add the seven back which will give you your answer of
4.7 10^8
