You are going to want to cross multiply this, so 5/9 would multiply with 1 and 2/3 would be multiplied by x. Now you have 5/9 = 2/3x. You would divide 2/3 on both sides and get 5/6. 5/6 is your answer.
Answer:
The answer is A
Step-by-step explanation:
If you plug in the numbers it looks like this:
(A) 5(2) + 10(5) = 60
(B) 10(2) + 5(5) = 45
(C) 7(2) + 8(5) = 54
(D) 8(2) + 7(5)
so a is the only one that equals 60
Answer:
Step-by-step explanation:
-x-2y+4z=-14
x=-2y+4z+14
2x+2y+2z=-6
2x=-2y-2z-6
x= -y-z-3
-x-6z=-3
x=3-6z
Answer:
-10
Step-by-step explanation:
the upper right is the same (105°), therefore the left 75°
now you have 180 = 75 + x + 115
therefore: -10
the equation is 2x-1 right so all you have to do is plug and go
2x-1
2x10-1
20-1
19
so your answer would be A)19
