Congruent angles of what... be more specific please..
Answer:
3 7/50
Step-by-step explanation:
so you need them to become common denominators
a common multiple they both have would be is 77
6/7 becomes 66/77 and 3/11 becomes 21/77
now we divide
keep the 66/77 as is and flip 21/77 (keep, change, flip)
so now our equation looks like this: 66/77 x 77/21
and your answer is 3.14
but as a fraction it is 157/50 and to simplified it would be 3 7/50 (mixed fraction)
Answer:
85.33%
Step-by-step explanation:
64/75=0.8533333...
x100 = 85.33%
2x + 3y = 9
x + 5y = 8....multiply by -2
----------------
2x + 3y = 9
-2x - 10y = -16 (result of multiplying by -2)
---------------add
-7y = - 7
y = -7/-7
y = 1
x + 5y = 8
x + 5(1) = 8
x + 5 = 8
x = 8 - 5
x = 3
solution is (3,1)
5 minutes x minutes
--------------- = -------------
4 dishes 24 dishes
using cross products
5 * 24 = 4 * x
divide each side by 4
5*24/4 = x
30=x
It will take 30 minutes
