2/3x - 1/2y = 3 |multiply both sides by 6
4x - 3y = 18
1/2x + y = 5 |multiply both sides by 2
x + 2y = 10
Answer: 4x - 3y and x + 2y = 10.
A. 25mpg $13,000 B. 45mpg $25,000 15,000 $4
15,000/25 = 600, 600x$4 = 2400 15,000/45 = 333.3, 333.3x$4 = 1333.3
2400 = 1333.3x x= 1.8
so 2 years
It is impossible to know because you haven’t completed your question , the formula isn’t complete
Is there more to the questions or is this all of it?
Answer:
2.3 x 10⁴
Step-by-step explanation:
23000 is the number. You need the decimal to be in between the two whole numbers that aren't 0.
2.3 <
2.3 x 10, the exponent after the ten has to move the decimal to the original number of spaces in the original number 23000.
In 23000 its 4 places so your answer would be
2.3 x 10⁴
