Supplementary angles add up to 180 degrees and with the given information you should be able to get the equation (3x+40)+80=180. Simply solve for X from there. X should equal 20.

What property is 7+(4+6)=7+n
Ket [755]

This looks like "half" a property. I'm assuming you mean something that looks like this:


IF a + b = a + c, THEN b = c. In the expression in your problem, the role of a is being played by 7. The role of b is played by (4 + 6), and the role of c is played by n.


The conclusion would be that 4 + 6 = n.


But you asked about what the property is called. The likely name is the subtraction property of equality. How did we go from a + b = a + c to the conclusion b = c? We subtracted a from both sides of the equation.

The equation of this circle is (x + <br> )2 + (y + <br> )2 = <br> .
Alex787 [66]

Answer:

x2 + y2 = r2, and this is the equation of a circle of radius r whose center is the origin O(0, 0). The equation of a circle of radius r and center the origin is x2 + y2 = r2.

I think this is the answer.

Find the probability that in a pig family of 4 offspring there will be at least 1 male and 1 female. Assume that the probability
Naya [18.7K]
The probability of there being zero males is given by:
P(zero\ males)=4C0\times0.5^{0}\times0.5^{4}=\frac{1}{16}
Similarly the probability of there being zero females is also 1/16.
The probability there will be at least 1 male and 1 female is therefore:
1-(\frac{1}{16}+\frac{1}{16})=\frac{7}{8}
The answer is: 7/8.

Use radical notation to rewrite each expression and simplify<br> 9 3/2
scoundrel [369]

Answer:

  9^{\frac{3}{2}}=\sqrt{9^3}=27

Step-by-step explanation:

The fractional exponent m/n is often translated to radical form as ...

  x^{\frac{m}{n}}=\sqrt[n]{x^m}

In this case, I find it easier to evaluate as ...

  x^{\frac{m}{n}}=(\sqrt[n]{x})^m=\boxed{(\sqrt{9})^3=3^3=27}
