Answer:
53, 55
Step-by-step explanation:
by the triangular inequality theorem, in a triangle.. sum of two sides is always greater than the third side.
3+54=57 ... exclude 57 and 58
3+51=54 ... exclude 51
0.012 as a fraction would be 12/1000, which can be simplified to 3/250. :)
let
x-------> workers in team one initially
y-------> workers in team two initially
we know that
x=2y-----> equation 1
(x-5)=(y-2)+7-----> x-5= y+5----> x=y+10---------> equation 2
equate equation 1 and equation 2
2y=y+10-----> y=10
x=2*10------> x=20
Team 1 now has 20-5 = 15 members Team 2 now hase 10-2 = 8 members
Answer:
The amount invested at 4% was $600
The amount invested at 7.5% was $3,600
Step-by-step explanation:
Let
x ----> the amount invested at 4%
$4,200-x -----> amount invested at 7.5%
we know that
The total interest earned is equal to the interest earned by the amount invested at 4% plus the interest earned by the amount invested at 7.5%
Remember that



so
The linear equation that represent this situation is

Solve for x





therefore
The amount invested at 4% was $600
The amount invested at 7.5% was $3,600
