$21000-$16000= $5000
$ 5000/21000 * 100%
= 23.8%
Answer:
3p = $2.10
p = $0.70
Step-by-step explanation:
Cost of a pencil: p
Cost of a pen: p × 2 = 2p
If the cost of 1 pen and 1 pencil is $2.10,
2p + 1p = $2.10
3p = $2.10
p = $0.70
Below are I assume the choices, it can be found elsewhere:
A. 15x+10y≥250
B. x+y≤250
C. x+y≥20
D. 15x+10y≥20
E. x+y≤20
<span>F. 15x+10y≤250
</span>
The inequalities that represent constraints for this situation is 15x+10y<=250 and <span>x+y>20. Thank you for posting your question here. I hope the answer helps. </span>
Answer:
140
Step-by-step explanation:
We have been given two fractions 
and 
. We are asked to find the least common denominator of both fractions.
To find the least common denominator of both fractions, we will find least common multiple of 20 and 28.
Prime factorization of 20: 
Prime factorization of 28: 
Least common multiple of 20 and 28 would be: 
.
Therefore, the least common denominator of both fractions would be 140.
