Answer:
- 1 pound- $4.7
- 2 pounds- $9.4
- 3 pounds- $14.1
- 4 pounds- $18.8
Step-by-step explanation:
Just hardware's prices are 0.30 greater per pound, so the equation would be y=4.7x. Substitute x in for each of the values to get the prices above.
Simplifying
30c + -45d
Factor out the Greatest Common Factor (GCF), '15'.
15(2c + -3d)
Final result:
15(2c + -3d)
Answer is c
use pythagorean
a^2 + b^2 = c^2
8^2+15^2= c^2
289=c^2
sqrt both sides
c=17
BC=17
(−4) − 6
<u>Remove Parenthesis</u>
-4 - 6
<u>Subtract the numbers: </u>
- 4 - 6 = 10
= −4 −6
= −4 + −6
<u>Answer = −10</u>
Hope that helps!!! : )
