Answer:
b i took the test that was the right answer
Step-by-step explanation:
Applying BODMAS (Order of operations rule)
Where: B is for brackets
O is for 'of' which means multiplication
D is for division
M is for multiplication
A is for addition
S is for subtraction
<u>In this case:</u>
We start with addition then we go to addition and finally we subtract.
(78 × 13) - (8 × 78) + (26 × 78) - 78
= 1014 - 624 + 2028 - 78
= 1014 + 2028 - 624 - 78
= 3042 - 624 - 78
=2340
Two significant figures.
The trailing zero is not significant
M is 3/2 because we need to Multiply to remove the variable from the denominator
17, because you divide 22 in half and add 6 because there are half as many mollies and there are 6 more guppies then goldfish.
