Answer:

\fbox{27}

Step-by-step explanation:

4x+3=3x+9\\4x+3-3=3x+9-3\\4x=3x+6\\4x-3x=3x-3x+6\\x=6

Plug in the 6 to the equations. Since B is the midpoint of AC, then both should be equal once plugged in [and solved].

4(6)+3\\= 27\\3(6)+9\\= 27\\\\\fbox{27}

Divide up to two decimal places.<br>12427 by 349<br>explanation please! thankyou.​

12427÷349

35.60744985673352

= 35.61(2d.p)

Explanation:

When you divide it you get 35.60744985673352

To leave it in to 2 decimal place, you are to consider the the third number after the point which in this case is 7. So you check if it is greater than or equal to or less than 5. If it is greater than or equal to 5 you carry forward 1 to the next digit to the left which is 0 in this case which will give you 1, then you retrieve the number plus the first two decimals after the point to get 35.61(2d.p).

I need help with this question. Can someone please help me with it. Thanks in advance

Okay, 72 degrees is equal to (5x-98), so
72=5x-98
5x=170
x=34

So now that we know that x=34, we can put 34 into (5x-98), so 170-98
170-98 and y are supplementary, so they add up to 180 degrees. So the equation is 
170-98+y=180
72+y=180
y=180-72
y=108
