Answer:
6.1 ⋅
Step-by-step explanation:
i think smh
6100 because 3.05 times 10^7 is 30500000 and 5* 10 ^3 is 5000
30500000/5000 is 6100 or 6.1*10 ^3
if we name that part x, then we can say
1/x = 1/a + 1/b
x = 4.
Distribute, isolate and solve.
231
=
42÷2= 21
9×21= 189
189 students total
42 6th graders
10x + 26 = 2x + 58
10x = 58-26
10x = 32
X = 3.2
I think??
