Answer:
168
Step-by-step explanation:
24 times 3 is 72 then also 24 times 4 is 96 add that and get 168
Answer:
1.8
Step-by-step explanation:
there are 100 cementers in a meter, 1000 millimetres in a meter, 1000/100=10 ,so 18/10=1.8
4x - 5y = -12
-x + 5y = 18
Add the equations together:
4x + -x = 3x
-5y + 5y = 0
-12 + 18 = 6
So now you have:
3x = 6
Divide both sides by 3:
X = 2
Now you have the value of x, replace x with 2 in one of the equations and solve for y:
4(2) -5y = -12
8 -5y = -12
Subtract 8 from both sides:
-5y = -20
Divide both sides by -5:
Y = 4
The solution is x = 2 and y = 4 which is written as (2,4)
To find the quotient, divide 396 by 12.
396/12= 33
