75 layers
15 layers/24 cm = x layers/120cm
(120*15)/24 = x
75 layers = x
195=275-275p
-275 -27
-80=-275p
You do -80 divided by -175 which is 0.45 and your answer is C45%.
It would be 6.0x4 because the square is 6.0 on each side
Answer:x=16
Step-by-step explanation:
4x+45=3x+61
Collect like terms
4x-3x=61-45
x=16
2x - 3y = -24
x+ 6y = 18
you solve the first one by the x:
2x = -24 + 3y
x = (-24+3y)/2
then you substitute what you found in the other equation and you solve by y
(-24+3y)/2 + 6y = 18 multiply everything by 2
-24 + 3y + 12y = 36
3y + 12y = 36 + 24
15y = 60
y = 60/15
y = 4
Good job! You found your y! :D
Now let's substitute the y in the first equation with 4:
2x - 3(4) = -24
2x - 12 = -24
2x = -24 + 12
2x = -12
x = -12/2
x= -6
Done!! ;) <span />
