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
It’s is number 1 hope this helpeddd!!!!
17.16 is 62.4% of what number?
'is' indicates an equal sign.
62.4% = 0.624
'of' indicates multiplication
'what number' indicates an unknown value that we can call 'x'
17.16 = 0.624 * x
17.16 = 0.624x
Divide 0.624 to both sides:
x = 27.5
It would be 2/10 or 1/5 simplified
