Answer:
Mr.Kim is presently 40 years old, and his daughter is 15 years old.
Step-by-step explanation:
K is Mr Kim's present age
D=his daughter's present age.
K=D+25 ; or Mr.Kim is his daughter's age plus 25 years.
K+10=2(D+10); or in 10 years, Mr Kim will be twice daughters age
Substitute the K from the first equation into the second equation and then solve for variable D.
(D+25)+10 = 2(D+10) Simplify.
D+35 = 2D+20 You must subtract D from both sides.
35 = D+20 Lastly, subtract 20 from both sides.
15 = D or D = 15
Mr Kim's daughter's is 15 years old.
Mr Kim's age is D+25
15+25 = 40 years old.
X/(9+11)=4 bc x is the “number” and “9, and 11” means add them together. Put the in parenthesis
Answer:
The answer to your question is:
a) sun to jupiter = 4.838 x 10 ⁸ miles
sun to earth = 9.296 x 10 ⁷ miles
b) 5.2 times
Step-by-step explanation:
distance sun to jupiter = 483 800 000 miles
distance sun to earth = 92 960 000 miles
a)
sun to jupiter = 4.838 x 10 ⁸ miles just move the decimal point eight places to the left.
sun to earth = 9.296 x 10 ⁷ miles just move the decimal point seven places to the left.
b)
divide distance sun to jupiter by distance sun to earth =
= 4.838 x 10 ⁸ / 9.296 x 10 ⁷
First divide 4.838 by 9.296 or 4.838 / 9.296 = 0.52
Then we substract the powers: 8 minus 7 or 8 -7 = 1
So we get 0.52 x 10¹ or 0.52 x 10 = 5.2 times
