Tony usually saves 1/5 of his allowance. Last week, he only saved 2/3 as much. How much of his allowance did he save last week?

2/15

Step-by-step explanation:

All we have to do is multiply 1/5 by 2/3

1  x 2 = 2

5 x 3 = 15

Therefore, Tony saved 2/15 of his allowance last week.

2/15

Step-by-step explanation:

you have to multiply 1/5 by 2/3

1  x 2 = 2

5 x 3 = 15

Therefore, Tony saved 2/15 of his allowance last week.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450
