Let s represent the cost of a pair of socks.
.. 15.95 +5s -4.20 = 10s
.. 11.75 = 5s
.. 2.35 = s
Any of the above equations will get you to the cost of a pair of socks, which is
$2.35.
Answer:
FOR H_2
Step-by-step explanation:
Given data:
concentration
WE KNOW THAT
therefore
Now for conversion of mol to gram need the molar mass of element in which particular value convert to.
let us take
we know that molar mass of is 2 gram
therefore
let take other example, for
we know that molar mass of O_2 is 32 gram
therefore
Answer:
sin∅ = 0.7311
Step-by-step explanation:
Pythagorean Theorem: a² + b² = c²
sin∅ = opposite/hypotenuse
Step 1: Find our hypotenuse
14² + 15² = c²
c = √421
Step 2: Find sin∅
sin∅ = 15/√421
sin∅ = 0.731055
Answer:
x = (22/17), y= (79/17)
Step-by-step explanation:
Just substitute x = 2y - 8 into y = 9x - 7 and solve.
