Answer:
-4 13/50
Step-by-step explanation:
11/45=0.24444 (repeating)
Let's round it to 0.24
0.24-4.5=-4.26 (-4 13/50)
2. $56= 8 hours
Want find out 42.5 hours earn how much
56 divide 8 = $7
42.5x7= 297.5
3. 40meters = 6 seconds
Need find out how many seconds of 1 meter
40 divide 6=6.6
120x6.6= 792 seconds = 13 hours and half 13.5
Answer:
You can take this equation into two approaches.
#1 subtracting 4x from both sides:
-3x+10=4x-20 (subtract 4x from each side)
-7x+10=-20 (then subtract 10 from each side)
-7x=-30 (then divide by -7 to get x by itself)
x=30/7
#2 Add 3x to both sides:
-3x+10=4x-20 (Add 3x to both sides)
10=7x-20 (then add 20 to each side)
30=7x (divide both sides by 7)
30/7=x
Either way you do it you will get x=30/7 as your answer.
Hope this helps ;)
