Answer:
x= 1.069Y
Step-by-step explanation:
kilometers = y
miles = x
y>x
5x = 8.045y
therefore,
8.045 divided by 5 to get value of X
hence,
X = <u>1.069Y</u>
Answer: 20
Step-by-step explanation:
(3+7)*2 = 20
Answer:
2^1* 3^7
Step-by-step explanation:
8^-1 * 3^3/ 2^-4 * 9^-2
Negative exponents move from the numerator to the denominator or from the denominator to the numerator
2^4*9^2* 3^3 /8^1
Rewriting 9^2 as 3^2^2 = 3^4 and 8 = 2^3
2^4 * 3^3 * 3^4 / 2^3
2^4/ 2^3 = 2 and 3^3 * 3^4 = 3^(3+4) = 3^7
2* 3^7
