Answer:
I think it's -6x-18, this queston uses distributive property, so you must multiply each term inside the parenthesis to the number outside the parenthesis.
Answer:
m∠RST = 155°
m∠RSU = 102°
Step-by-step explanation:
m∠RST = m∠RSU + m∠UST
12x - 1 = 9x - 15 + 53
12x - 9x = 1- 15 + 53
3x = 39
x = 39/3
x = 13°
m∠RST = (12x -1)° = (12 * 13 - 1)° = (156 - 1 )° = 155°
m∠RSU = (9x -15)° = (9 * 13 - 15)° = ( 117 - 15)° = 102°
The answer to the question is x=-12.1hopes this helps you.
<span> Step 1: subtract X from both sides.
0.5x-6-x=x+0.05-x
-0.5x-6=0.05</span>
Step 2: Add 6 to both sides.
-0.5x-6+6=0.05+6
-0.5x=6.05
Step 3: Divide both sides by -0.5.−0.5x−0.5=6.05−0.5
For this case we have the following expression in units of minutes:

As the exponent is positive we run the decimal six spaces to the right:

We have 1 hour has 60 min, then:

On the other hand, we have one day has 24 hours.

Likewise, a month has 30 days:

Also, one year has 365 days:

Finally, Mia is 13 years old equivalent to 160 months, which is equal to 4817 days.
