3t -7 = 5t
Minus 3t over
-7= 2t
t= -7/2
6(t) = 6(-7/2) = -42/2 = -21
6t = -21
The answer is 14 if you're just wanting to divide 84 by 6
All triangles have 180o in them when the 3 angles making them up are added together.
Givens
F = 90
E = 29
D = ???
Equation
<D + <E + <F = 180
Substitute and solve
<D + 90 + 29 = 180
<D + 119 = 180
<D = 180 - 119
<D = 61
Answer:
D
Step-by-step explanation:
100+25 * 12 ; 100+300 = 400 ; difference = 400-320=80 ; percent increase since it is 1 year = 80/320 =1/4=0.25 = 25/100=25%
