Answer:
t = 20 + q in minutes
Step-by-step explanation:
Company meeting = president speech + questions + answers
President speech = 20 minutes
Questions and answers = q minutes
Total time spent = t minutes
Total time spent = President speech + Total time spent
t = 20 + q
The equation that represents the relationship between q and t is
t = 20 + q in minutes
Answer:
31.35/ 2.85= 11 packages (it's exact, no decimals)
It is a simple linear equation with one unknown, we can solve it:
(x/2) - 2 = 9
<span>(x/2) = 9 + 2 = 11
</span>x = 2*11
x = 22
that is the equation's solution
Hello there!
-6x + 5 - 4(x - 1) = -4x - (5x - 3) + 4
We need to use the distributive form
-6x + 5 + (-4)(x) + (-4)(-1) = -4x - 5x + 3 + 4
-6x + 5 - 4x + 4 = -4x - 5x + 3 + 4
-10x + 9 = -9x + 7
Now we can subtract 9 from both sides
-10x + 9 - 9 = -9x + 7 - 9
-10x = -9x - 2
Add 9x to both sides
-10x + 9x = -9x + 9x - 2
-x = -2
We cannot leave it with a negative sign, divide both sides by -1
-x/-1 = -2/-1
x = 2
I hope the steps are clear to understand. If you have any misunderstanding feel free to let me know.

Answer:
3 * 10 ^-2
Step-by-step explanation:
When we divide numbers in scientific notation first divide the number portion
2.7 /9 =.3
Then divide the exponents
10 ^5 / 10 ^6 = 10 ^ (5-6) = 10 ^ -1
.3 * 10 ^-1
We cannot leave the .3 since the first number has to be between 1 and less then 10
Move the decimal 1 place to the right which means subtract 1 from the exponent
3 * 10 ^-2
