Yes you are correct aaaaaa
36. you have to multiply the whole thing.
Hello!
To solve this, we will use a system of equations. We will have the numbers be represented by x, y, and z, where x will represent the first, y the second, and z the third.
x+y+z=54
z=2x
x=6+y
We know that x is equal to 6+y. We can plug this into the second equation to find z.
z=12+2y
Now we can plug these y values into the first equation to find y.
6+y+y+12+2y=54
18+4y=54
4y=36
y=9
Now we know the value of y. We can plug this into the equations to find the other values.
x=6+9
x=15
z=15(2)
z=30
Just to check, we will add them all up and see if they equal 64.
15+9+30=54
The first number is 15, the second is 9, and the third is 30.
I hope this helps!
LCM of 25 and 35.
25 = 5 x 5
35 = 5 x 7
LCM = 5 x 5 x 7 = 175
Therefore, she will have both lessons 175 days from today.
