I believe it is not a tight trying because as I was taught, A+B=C & C-A=B which does not work out in this case.
Answer:
Step-by-step explanation:
Angles around a point add up to 360
x + 53 + 37 + 139 = 360
x + 229 = 360
x = 360 - 229
x = 131
Answer:
For the first blank box, it would be 2, and for the second blank box, 40
Step-by-step explanation:
As we are told, we need 3 sticks of butter for every 24 cookies. We can make this simple by figuring out how many cookies we can make with one stick of butter.
To do this is easy: 24 divded by 3 = 8
So 8 cookies per stick of butter
16 cookies would be 2 sticks of butter (as 8 x 2 is 16, and there's 8 cookies per butter stick)
and with 5 sticks of butter, we do (5 x 8 ) which equals 40
Hope this helped !
Answer:
x=4 and x=-3
Step-by-step explanation:
You have to set each one equal to zero and solve for x
x-4=0 x+3=0
+4 +4 -3 -3
x=4 x=-3
3 hours because 8-5= 3 for 3 total hours more
