Answer:
60
Step-by-step explanation:
Answer: Number of children = 168
Number of adults = 120
Step-by-step explanation:
Let x = Number of children and y = Number of adults
As per given,
x+y=288 (i)
2.25x+6.80y =1194 (ii)
Multiply 2.25 on both sides in (i)
2.25x+2.25y= 648 (iii)
Eliminate (iii) from (ii)
4.55y=546
Put y= 120 in (i)
x+120=288
⇒ x=288-120
⇒ x= 168
Hence, Number of children = 168
Number of adults = 120
<span> Assume that the expression is..
y/3 + ¼ = 5/12
Multiply both sides by 12 to get..
4y + 3 = 5
Then...
4y = 5 - 3
4y = 2
y = 2/4
y = ½
I hope this helps! </span>
Answer
equation: 2(3x-9) + 2(2x+4)= 60
length: 36 meters
width: 24 meters
Step-by-step explanation:
2(3x-9) + 2(2x+4)= 60
6x-18 + 4x +8 =60
60+18-8= 10x
70=10x
x=7
length- 2(2(7)+4) = 36
width- 2(3(7)-9)= 24
