Answer:
x=8
Step-by-step explanation:
(6x+4)+(4x+6)=90
10x+10=90
-10 -10
<u>10x</u>=<u>80</u>
10 10
x=8
Answer:
Step-by-step explanation:
- No different person will have different drawings because you had not mentioned the sides length so every person will take only angle of 50 degree in account not sides, he will draw the sides of his own well,
- and also may be there is some instruments error also .
The answer is x is equal to 2
Answer:
3.5x + 15 ≥ 55
Step-by-step explanation:
I think the question below contains the missing information.
<em>Josh has a rewards card for a movie theater. - He receives 15 points for becoming a rewards card holder. - He earns 3.5 points for each visit to the movie theatre. - He needs at least 55 points to earn a free movie ticket. Which inequality can Josh use to determine x, the minimum number of visits he needs to earn his firs free movie ticket?
</em>
My answer:
- Becoming a member = 15 points
- Visiting the moving theater = 3.5 points
- Total points needed for a free movie ticket = 55
Let x is the number of times he visits = 3.5x
Total points = Points received on becoming a member + Points received on x visits
So,
Total Points = 15 + 3.5x
We know the total points must be at least 55 for a free movie ticket. This can be expressed as:
3.5x + 15 ≥ 55
Use the FOIL method: First, Outside, Inside, Last
3x(2x) = 6x²
3x(-4) = -12x
3(2x) = 6x
3(-4) = -12
6x² -12x + 6x-12
Combine like terms
-12x + 6x = -6x
6x² - 6x - 12 is your answer
hope this helps
