Answer: x=9
Step-by-step explanation:
2x+10=28
2x=18
x=9
258 = 240 + 18
258: 6 = (240 + 18) : 6 = 240 : 6 + 18 : 6 = 40 + 3 = 43
Your answer is 43.
0.3 is 3/10, (which is already simplified) because .3 is out of 1. Which means that that 1 is 10. Which is 3/10.
You could cross cancel the a and your final answer would be 5/11
