Answer:
What graph
Step-by-step explanation:
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
16 ounces in a pound.
100 divided by 16 = 6.25 pounds, or 6lb 4oz.
The first figure, on left, is the composition of two areas, the area of a 7cm circle and the area of a 7 cm square so:
A=7^2+7^2π/4
A=49+49π/4
A=49(1+π/4) cm^2
A≈87.48 cm^2 (to nearest hundredth of a square centimeter)
...
The second figure is the area of a 15cm by 8cm rectangle minus the area of a 3cm circle so:
A=15(8)-3^2π/4
A=120-9π/4
A=120-2.25π cm^2
A≈112.93 cm^2 (to nearest hundredth of a square centimeter)
Well, whenever a number is next to a variable or next to parenthesis, (a variable is the letter[s] used to represent a value in the problem, such as 3b in this question), that means you would multiply the number times the letter, or the number times the answer in the parenthesis. So since we know a = 9, and b = 2, let's solve the equation now! :D
Now according to the order of operations of PEMDAS, let's solve what's in parenthesis first.
5(a + 3b)
⇒ a + 3b
⇒ a (a = 9), + 3 times b (b = 2)
⇒ 9 + 3 × 2
⇒ 9 + 6
⇒ 15.
⇒ 5(15)
⇒ 5 × 15
⇒ 75.
After doing all steps with the help of the order of operations of PEMDAS, your final answer would be 75. =)
I hope I helped! ^-^
