Answer:
d = 2.75 or 11/4
Step-by-step explanation:
15 = 5 + 4(2d - 3)
15 = 5 + 8d - 12
15 = 8d - 7
<u>+7 + 7</u>
22 = 8d
22/8 = d
2.75 = d
Check:
15 = 5 + 4(2(2.75) - 3)
Answer:
Step-by-step explanation:
1. This is a arithmetic sequence, so the equation is 
.
is -33 and the d is -33.
So, the equation is 
.
Absolute value is always positive.
2 = 4
Not true.
First add the ratios together:
2 + 7 = 9
Then divide this from 747:
747 / 8 = 83
Finally, multiply this by the ratios
2 x 83 = 166
7 x 83 = 581
So 747 would be shared by :
166 to 581
Write it out as an equation:
3 < 1/3P
Rewrite so P is on the left side:
1/3P >3
Multiply each side by 3:
1/3P x 3 > 3 x 3
Simplify:
P > 9
