You buy 11 bagels with a 20$ bill how m if change do you receive? how many bagels could you buy?
Svetllana [295]
Change you’ll receive is = 0.09
you can only buy 11 because if you divide 20/11 it will give you 1.81 and if you multiply 11x 1.81 it will give you 19.91 which is close to $20 & that’s the most you can buy .

P(x) = 3x2 - 7x + 11, find P(9).
nadya68 [22]
You need to substitute 9 with every x value in the equation. 
So, 3(9)^2-7(9)+11
p(x)= 191

Need help plzzz???!?????!
Shkiper50 [21]

Answer:

137

Step-by-step explanation:

First start with what you know.  The measure of the interior angles of a triangle total to 180^{o} so 51 + 2x + x = 180, then 51 + 3x = 180, 3x = 129, so

x = 43, the exterior angle is on a straight line with x so

x + exterior angle = 180 [since they are supplementary], since x = 43 then

43 + e = 180, so e has to be 137
