Multiply, then you get 2a - 10 = -2. Then isolate the variable by adding 10 on both sides. you get 2a = 8. divide both by 2 and you get a = 4
Answer:
1
Step-by-step explanation:
I believe the answer to this is one. A numerical coefficient is a constant multiplier of the variables in a term. Since the term is only an x, you always put a one before an x. Therefore, the numerical coefficient is 1.
convert to exponential form
8^x=512=8^3
x=3
The logarithm of 512 to the base 8=3
Answer:
Subtract:
2/3 - 1/2 = 2/3 • 2/2 - 1/2 • 3/3 = 4/6 - 3/6 = 4-3/6 = 1/6
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(3, 2) = 6. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 3 × 2 = 6. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - two thirds minus one half = one sixth.
