Step 1: 198 ×
= 66, the number of men who left the party
Step 2: 256×
= 64, the number of women who left the party
66+64=130
Since 130 is the number of people that left, you would subtract it from the total number of people at the party originally.
198+256=454
454-130=325
So, 325 people are left at the party
Answer:
5.) b = -2/5 (or -0.4 in decimal form)
6.) 20.5
Trial and error but that will take time so there is a formula for it hope this helps
All you do is multiply across. For example...
1/3 x 2/5
Multiply the numerators and denominators.
(1 x 2) / (3 x 5)
= 2/15
If you need to, you can simplify but in this case you don't have to.
I hope this helps love! :)
