Nearest dollar = 97       .20 * 97 = $ 19.40 tip

Cross multiply the two terms on the left

7(x-3) + 3 (x+3) =  x (x+3)

10x -12   = x^2 + 3x

x^2 -7x+ 12 = 0

(x-4)(x-3) = 0

x = 4            x = 3  (not allowed....denominator would be 0)

36 possible rolls

65

56    are the only two that sum to 11      2/36 = 1/18 = .056

volume =  1/3 * pi * r² * h

             = 1/3  * pi * 6² * 4 = .......... units³

cylinder volume / cone volume = # times

(pi r^2 h )  / [ 1/3 (pi r^2 h) ]

(pi 4^2 * 3) / ( 1/3 ( pi 4^2 * 3) = # times = ........

Area of a circle =  pi r^2 

Larger circle - smaller circle = shaded area

pi ( 10^2 - 5^2 )  =  75 pi = ...........   units²

the sum of the lengths of the first 2 sides        I assume this is what you meant

l    +       l-3     +   2/3 (l  + l-3)  = 6.5

2l    +  4/3 l     - 3   - 6/3 = 6.5

10/3 l - 5 = 6.5

10/3  l   = 11.5

l = 11.5  *  3/10

l = 3.45  ft

l-3 = .45  ft

final leg = 2.6  ft

Multiply the numerator and denominator by   1 + 2i

to get

(-5 + 10i)/5  =   -1 + 2i

1111  has 4 ones     divide by   11   =   101     two ones ...half as many

1003

5.88 x 10¹²     miles is a light year (given)

    multiply this by 8.5

= 49.98 x 10¹²

~~ 5.0 x10¹³  miles (rounded)

37.5 x 10⁶   + 7.1 x 10⁶  =   44.6 x 10⁶ = 4.46 x 10⁷
