Determine the quotient of (7.7 × 10–2) ÷ (2.2 × 10–2). Write your answer in scientific notation. A)

3.5 × 10–2

B)

3.5 × 10–4

C)

3.5

D)

3.5 × 104

C) 3.5

Step-by-step explanation:

You do 7.7 divided by 2.2 which gives you 3.5. Then just divide the exponents seperately and when dividing you subtract the exponents. Since you are subtracting you will have (-2)-(-2) and when you subtract a negative number it becomes addition because the two --  cancel out. So it is -2+2 which is equal to 0. 10 to the power of 0 (or any number to the power of 0) is always equal to 1. So 3.5 x 1 is the answer which gives you C.

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
