Answer:
34
Step-by-step explanation:
We know the straight line is equal to 180°, and the three angles that make it are (x+12),100°, and x. We can use the equation 180=(x+12)+100+x to find x.
180=(x+12)+100+x
We can remove the parentheses and combine x plus x to 2x.
180=100+2x+12
100+12=112
so
180=112+2x
-112 -112
68=2x
÷2 ÷2
34=x
Answer:-1.2
Step-by-step explanation:
Not any separable equation is exact..M(x) + N(y) (dy/dx) = 0Multiply across by dxM(x)dx+N(y)dy=0.
the equation is going to be exact if and only if:Mx = Ny
Answer:
5.66 inches
Step-by-step explanation:
In this case I know the ratio or that 1 inch equals 12 miles, so 1 times 12. I need to find out how many inches represents 68 miles, so 12 times what number equals 68? I would divide 68 divided by 12 and I get 5.66 that terminates, the teacher should accept 5.66 inches or 5 and 2/3.
