The 3 inside angles of a triangle need to equal 180
you have 80 +60 = 140
so 51+x has to equal 180-140 or 40 degrees
51+x = 40
subtract 51 from each side
x = 40 - 51
x = -11
Answer:
99.75lbs.
Step-by-step explanation:
4 x 18.5= 74lbs
2 x6.75= 13.5
14x 7/8 =98/8=12.25
Answer:
slope intercept form of the equation for these points would be y=2x-7
standard form of linear equations for this equation would be: -2x+y=-7
Step-by-step explanation:
<span>fourth degree polynomial with three terms
the degree is the highest exponent the term are separated by plus or minus </span>
They are equal so...
15x+2 = 9x+20
15x-9x = 20-2
6x =18
x = 18/6 = 3
x = 3
