Answer:
33-9+40-(30+15) =
33-9+40+25-(30+15) =
3+21 x 6-(24-4) =
3+21 x 6-(24-4) x 2 =
(62 ÷ 2 – 3) x 3 +6 =
(62 ÷ 2 – 3) x 3 +6 x 2=
0.3+0.8+0.2=
30+30×0+1=
Step-by-step explanation:
Step-by-step explanation:
log 25 + log 8 = log (25 × 8) = log 200
log 200 - log 2 = log (200 ÷ 2) = log 100
logarithm base 10 of 100 is 2.
Generally we use n as a counter and begin it with 1: the first term is obtained when n = 1. Thus, n must be a positive integer, 1 or greater: {1, 2, 3, ... }.
Idk what linear combination is but you can solve this way:
3x+y=4
-2x-y=-5
x=-1
3(-1)+y=4
-3+y=4
y=7
So x=-1 and y=7
