Answer:
45
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180
2x - 12 + 2x + 17 + 9x - 7 = 180 add like terms
13x - 2 = 180 add 2 to both sides
13x = 182 divide both side by 13
x = 14
m<X = 2x + 17 replace x with 14
2*14 + 17 = 45
4 Oranges, 310 divided by 5= 64, 64 times 4=248.
Answer:
46,000,000 (46 million)
Step-by-step explanation:
If the number to the right (in this case the hundred thousands place) is 5 or greater then you round up.
If it was lower than 5 you would round down.
As the number in the hundred thousands place is 6, this means we can round up.
(5, 3)
x y
Plug in:
x + y = 8
5 + 3 = 8
8 = 8
Plug in:
17(5) + 17(3) = 8
85 + 51 = 8
136 = 8
Answer - No, (5, 3) is not a solution to this system of equations.
Answer:
(5 x (-20)) * (100 x (0.7))
