Step-by-step explanation:
The total number of writing utensils is 6, explaining the denominator. the numbers of pens added together is 5, explaining the numerator.
Answer:
Total charge= -25
Step-by-step explanation:
Given :
Charges of some ions
Aluminium +3
Phosphate -3
Chloride -1
Silver +1
To find total charge on 8 phosphate,7 chloride and 2 Aluminium atoms
Aluminium +3 × 2 =+6
Phosphate -3 × 8 = -24
Chloride -1 × 7 = -7
total charge=
+6-24-7 =+6 -31
= -25
Well, let's use the Euclidean algorithm:
164 = 4×37 + 16
37 = 2×16 + 5
16 = 3×5 + 1
Then working backwards,
1 = 16 - 3×5
1 = 16 - 3×(37 - 2×16) = 7×16 - 3×37
1 = 7×(164 - 4×37) - 3×37 = 7×164 - 31×37
so that x = 7 and y = -31.
$16 is the answer
Maybe I’m actually not sure
