Travel distance by light in a second = 3*10^5 kms
Travel distance by light in 60 seconds =
3*10^5 * 60
180 * 10^5
1.8 * 10^7 kms
Answer:
c. 25
Step-by-step explanation:
100/12 = 8.3
8.3 × 3 = 24.9
rounded up is 25
3x * 3x = 9x
9x + 6 - 2x + 5x - 4x^2 + 9
9x + 6 - 7x - 4x * 4x + 9
9x + 6 - 7x - 16x + 9
9x + -7x = 2x + 6 - 16x + 9
2x + 6 - 16x + 9
2x + (-3) - 16x
-14x + (-3) is the expression?
Y=2x+3 is a linear equation.
