Answer:
p=56
Step-by-step explanation:
multiply by 7 to get it out of denominator
You are given the
length of the chain equal to 28.9cm. For each link, the length is 1.7cm long. You
are required to find how many links are there in the chain. You just divide
28.9 cm by 1.7 cm to get the answer. The solution is,
<span>
Number of links =
chain length/link length</span>
Number of links = (28.9cm)/(1.7cm)
<span>Number of links =
chain length/link length</span>
Number of links = 17
<span><u><span>There are 17
links in a 28.9cm chain length.</span></u><u /></span>
Answer:
(2, - 4 )
Step-by-step explanation:
Given the 2 equations
x + 2y = - 6 → (1)
3x + y = 2 → (2)
Multiplying (2) by - 2 and adding to (1) will eliminate the term in y
- 6x - 2y = - 4 → (3)
Add (1) and (3) term by term to eliminate y
- 5x = - 10 ( divide both sides by - 5 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
2 + 2y = - 6 ( subtract 2 from both sides )
2y = - 8 ( divide both sides by 2 )
y = - 4
Solution is (2, - 4 )
