".





15.
4(x-2) = 2(x-4)+2x
i used the distributive property on the parantheses to then get...
4x-8 = 2x-8+2x
I combined the like terms to then get...
4x-8 = 4x-8
+8 +8
4x = 4x
which simplifies to....
x=x
so the answer to question 15 is x=x
17.
-4(p+1) = -2(8-2p)
I used the distributive property on the parantheses....
-4p-4 = -16+4p
+4 +4
-4p = -12+4p
-4p -4p
-8p = -12
÷-8 ÷-8
p = 1.5
so the answer to question 17 is p = 1.5
hope this helps!!!!
Think of it as the amount of spaces you move on a number graph. so for example from -3 to -7 is 4 spaces. i hope you find this helpful!
It's y10, use your distributive property and you'll be good to go
Initial flow rate: 74 gallons/33 minutes = 2.24 gallons/minute
Additional flow rate: 2*74/33 = 4/48 gallons/minute
Total new rate: 3*74/33 = 6.72 gallons/minute
the answer is 6.7
