Answer:
Step-by-step explanation:
12(5+2y)=4y-(6-9y)
Distribute
12*5 +12*2y = 4y - 6 +9y
60 +24y = 4y - 6 +9y
Combine like terms
60+24y =13y -6
Subtract 13 y from each side
60 +24y-13y=13y-13y -6
60+11y = -6
Subtract 60 from each side
60+11y-60 =-6 -60
11y = -66
Divide by 11
11y/11 = -66/11
y =-6
Check
12(5+2(-6))=4(-6)-(6-9(-6) )
12 (5-12) = -24 - (6+54)
12(-7) = -24 -60
-84 = -84
True so the solution is correct
Answer:
Length of the pieces are 25 and 50 cms.
Step-by-step explanation:
If one piece is x cm long then the other is 75-x cm.
Difference is 25 cm , so:
75 - x - x = 25
-2x = -50
2x = 50
x = 25.
I think it’s 35w because you distribute: 24w+11w ) and then you add.
Answer: 75 feet
Step-by-step explanation:
One yard is equal to three feet.
multiply three by 25
or add 25 three times
The second one is same !
as 2x-2+3x= 5x-2 .....so answer is B
