I think associative property of addition
A. 16 is divisible by 2 but not divisible by 3
B. 23 is not divisible neither by 2 nor 3
C. 27 is not divisible by 2, however it's divisible by 3
D. 36 is divisible both by 2 and 3
So the only number we can focus on is 36:
36 ÷ 2 = 18
36 ÷ 3 = 12
36 ÷ 6 = 6
Answer: D, 36 supports the given conjecture.
Here you have 2 linear equations and are to solve this system. Both equations have already been solved for y, so you can set one of them = to the other one:
-2x+11 = -3x+21.
Then 3x-2x = 21 - 11, or x = 10 (answer)
Find y by subst. x = 10 into either of the given equations.
Solution is then (10, ? )
Answer:
-2.2
Step-by-step explanation:
By using the equation 5*(4+x)=9, when you isolate x you get -2.2.
Answer:
-45
Step-by-step explanation:
5 *-1 *-3= 15
4 *-3 *4= -48
3 *4 *-1=-12
15 -48 -12= -45
