Answer:
Step-by-step explanation:
I don't know. But I know how to find it. Let's work it out together:
<u>5x = 2x + 20</u>
Subtract 2x from each side: 3x = 20
Divide each side by 3 : <em>x = 20/3</em> or ( 6 and 2/3 ).
Answer:
<h2>
B. ST = 2</h2><h2 />
Step-by-step explanation:
|<-------------- 10 --------------------->|
S-------------------T--------------------U
X-6 2X - 8
FIND: ST
SOLUTION:
ST + TU = SU
x - 6 + 2x - 8 = 10
combine like terms:
3x - x = 10 + 8 + 6
x = 24/3
x = 8
plugin the value of x= 8 into the ST = x - 6
ST = x - 6
ST = 8 - 6
ST = 2
proof:
x - 6 + 2x - 8 = 10
8 - 6 + 2(8) - 8 = 10
10 = 10 ---OK
Answer:
22,950
Step-by-step explanation:
subtract 51,550 and 28,600. 0 - 0 = 0 then 5-0=5 5-6 you can not do so you barrow from the 1. 1 becomes 0 and 5 becomes 15. 15-6=9. 0-8 you can not do so you need to borrow from the 5. 5 becomes 4 and 0 becomes 10. 10-8=2. Finally, 4-2=2. Put is all together and you have 22,950.
