Hi if you know this pls answer it thank you!!

Step-by-step explanation: just count how many lines between x and x' to the right its positive to the left its negative

we have that

1.93 × 107 − 9.7 × 106

we know that

applying the rules for order of operations

first multiply

1.93 × 107 − 9.7 × 106

(1.93*.7*106)=206.51-1,028.2

second subtract

206.51-1,028.2=-821.69

therefore

the answer is

-821.69
