Answer:
x = 6
Step-by-step explanation:
The sum of the angles of a triangle is 180
70+60+8x+2 = 180
Combine like terms
132 +8x = 180
Subtract 132 from each side
132+8x-132= 180-132
8x = 48
Divide each side by 8
8x/8 = 48/8
x = 6
200 billion is 200,000,000,000 lbs
1 ton is 2,000 lbs.
So 200,000,000,000/2,000 = 100,000,000 tons or 100 million tons.
3 I believe because I did it differently
Answer:
2000-1200+111
2000-1311
689 <u>an</u><u>s.</u>
Step-by-step explanation:
by bodmas ( bracket,of,divide, multiplication, addition, substract )
so, <em><u>first</u></em> we'll multiply
3x400=1200
so,
2000-1200+111
<em><u>second</u></em><em><u> </u></em><em><u> </u></em> , we'll add
1200+111 = 1311
so,
2000-1311
<em><u>third</u></em><em><u> </u></em> , at last we'll subtract
2000-1311 = 689
so,
<em><u>Ans</u></em><em><u>.</u></em><em><u> </u></em>689
hope the ans. is correct :)
The answer is this math is pointless and after the test you will never use it again
