Ángel A And B are suplementary. Ángle A has a measure of 80.ehat is the measure of B?

zavuch27 [327]

Because supplementary angles means mA + mB = 180.
Then subtract 80 from 180 which will get you 100.
So B = 100

Nari says, "The sum of 10 and one-third of a number is 25." She uses the bar model to write an equation to represent her

Mariana [72]

Answer:

$25=10+\frac{1}{3}n$ .

Step-by-step explanation:

It is given that the sum of 10 and one-third of a number is 25.

Let as consider n be the unknown number.

One-third of a number $=\frac{1}{3}n$

Sum of 10 and one-third of a number $=10+\frac{1}{3}n$

The sum of 10 and one-third of a number is 25. It can be written as

$25=10+\frac{1}{3}n$

Therefore, the required equation is $25=10+\frac{1}{3}n$ .

Solve -7x^2+x+9=-6x quadratic formula

myrzilka [38]

Answer:

$-7x^2+x+9=-6x$

$-7x^2+x+9+6x=-6x+6x$

$-7x^2+7x+9=0$

$quadratic\: formula$

$x_{1,\:2}=\frac{-7\pm \sqrt{7^2-4\left(-7\right)\cdot \:9}}{2\left(-7\right)}$

$\sqrt{-7^{2} -4(-7)\times9} =\sqrt{301}$

$x_{1,\:2}=\frac{-7\pm \sqrt{301}}{2\left(-7\right)}$

$\frac{-7+\sqrt{301}}{2\left(-7\right)}$

$=\frac{-7+\sqrt{301}}{-2\cdot \:7}$

$=\frac{-7+\sqrt{301}}{-14}$

$\frac{-7-\sqrt{301}}{2\left(-7\right)}$

$=\frac{-7-\sqrt{301}}{-2\cdot \:7}$

$=\frac{-7-\sqrt{301}}{-14}$

$answer=\frac{7+\sqrt{301}}{14}$
