Answer:
Step-by-step explanation:
Here is the workings
2x+4y+6+2y-5+3x combine like terms
2x+3x+4y+2y+6-5
Step 2
2x+3x+4y+2y+6-5 Add the similar exponents
5x+4y+2y+6-5
5x+6y+6-5
Step 3
5x+6y+6-5 Add and subtract
Your answer would be 5x+6y+1
A = speed of one boy
<span>a + 3 = speed of 2nd boy </span>
<span>d = speed X time ... time is 3 hrs </span>
<span>68 = 3a + 3(a + 3) </span>
<span>6a = 59 </span>
<span>a = 59/6 = 9 5/6 miles per hour </span>
<span>a + 3 = 12 5/6 miles per hou</span>
Answer:
Original: $733 million
Sequel: $860 million
Step-by-step explanation:
Let's say the original movie grossed x dollars. Since the sequel grossed 127 million more than that, we can write the expression x + 127 to represent the sequel.
Their total is 1593 million, so let's add them up:
x + (x + 127) = 1593
2x + 127 = 1593
2x = 1466
x = 1466/2 = 733
To find the sequel gross amount, add 127 to 733:
127 + 733 = 860
So, the original movie grossed $733 million, while the sequel grossed $860 million.
