Trevon have 692 paper clips after buying 500 more clips.
Step-by-step explanation:
Let,
Paper clips Caroline have = x
Paper clips Trevon have = y
According to given statement;
x = 5y Eqn 1
After Trevon buys another 500 paper clips, he has 268 paper clips fewer than Caroline.
y + 500 = x - 268
y + 500 +268 = x
y + 768 = x Eqn 2
Putting value of x from Eqn 2 in Eqn 1
Dividing both sides by 4
Number of paper clips Trevon has now = y+500 = 192+500 = 692
Trevon have 692 paper clips after buying 500 more clips.

Answer:
- 4% fund: $39,000
- 52% fund: $1000
Step-by-step explanation:
Let x represent the amount invested at 52%. Then (40000-x) is the amount invested at 4%. The total annual interest is ...
0.52x +0.04(40000-x) = 2080
0.48x = 480 . . . . . . . . . subtract 1600, simplify
x = 1000 . . . . . . . . . divide by 0.48
Then the amounts invested in each fund are ...
4% fund: $39,000
52% fund: $1000
Answer:
105/8 = 13 1/8 = 13.125
Step-by-step explanation:
The first step is to turn the (-5 5/8) into a mixed number. The mixed number you should be getting is - 45/8. The second step is to convert the (-2 1/3) into a mixed number as well, your second mixed number should be -7/3. Next multiply the two fractions, - 45/8 x (-7/3) = 315/24.
We can simplify 315/24 by dividing by 3, so you'll divide 315 divided by 3 and 24 divided by 3 and you should get ... 105/8. So 105/ 8 is equal to
13 1/8. If you need this fraction in decimal form it is 13.125.
The value of x is 14 I think
