6x - 6 - 7x = -13/2
Multiply both sides by 2:
12x - 12 - 14x = -13
Simplify:
-2x - 12 = -13
Add 12 to both sides:
-2x = -1
Divide both sides by 2:
-x = -1
Change to a positive value of x:
x = 1
Answer:
366.
-1493.
Step-by-step explanation:
54.8-6.9-12
You perform the multiplications first:
= 432 - 54 - 12
= 378 - 12
= 366.
5-2.83.9-4
= 5 - 166* 9 - 4
= 5 - 1494 - 4
= -1489 - 4
= -1493
Answer:
If R is equal 5.1, Let x be A/A0
Then we have logx=5.1
Solving this we have x=125893
Answer:
The chances are very high because there are more nickels then there quarters, dimes, and pennies.
Step-by-step explanation:
The first expression 3^2 · 5 · 7 and the fourth expression 3^3 · 11 show a number as a product of prime numbers in exponential form.
3^2 · 5 · 7 shows 315 as a product of prime numbers 3, 5 and 7, that is 3 · 3 · 5 · 7
In 4^2 · 5 · 7, the number 4 is composite which can still be written as product 2 · 2
For the third one 3^3 · 8, the number 8 is composite which can still be written as product 2 · 2 · 2
The fourth expression 3^3 · 11 shows 99 as a product of prime numbers 3 and 11 which is 3 · 3 · 11
