Step-by-step explanation:
5y=60
y=60/5
y=12
Answer:
9
Step-by-step explanation:
The sum of ten and four gives you 14, so if the other line has the same angle, 5 and 9 give you 14
Answer:
9x + 1 = 7x + 13
<=> 2x = 12
<=> x = 6
with x = 6, UW = 7.6 + 13 = 55

Answer:
1 zinc
2 chlorine
Step-by-step explanation:
check your periodic table
In this problem we need to find the value of a and b. So given that t<span>he function should be in the form f(n) = an + b and we know each value of n, then out goal is to find a and b.
For getting this purpose, we need to find a system of two equations (given that we have two unknown variables)
Therefore:
(1) f(0) = a(1) + b = 18
</span>∴ a + b = 18
<span>
(2) f(1) = a(2) + b = 24
</span>∴ 2a + b = 24<span>
Solving for a and b we have:
a = 6
b = 12
Finally:
f(n) = 6n + 12</span>
