Step-by-step explanation:
The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
7×3 -4(225÷32)×2
7×3 -4(7.03)×2
21 - 8 (7.03)
21 - 56.25
= - 35.25
A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs $68. A season ski pass costs $300. The skier would have to rent skis with either pass for $20 per day. How many days would the skier have to go skiing in order to make the season pass less expensive than the daily passes?
first, ignore the rent for the skies. we could add it to both, but since it's the same, it would not change the number of days here.
this information is meant to test your decision making on what's important for the question.
now just ask how often you can pay $68 dollars per day while staying below 300 in total, you can just count it up.
68, 136, 204, 272, 340
its 4 days
for 5 days or more, the season pass is the better option

What is the value of x?
9514 1404 393
Answer:
x = 98°
Step-by-step explanation:
The polygon has 7 sides, so the sum of its interior angles is ...
180° × (7 -2) = 900°
The missing angle is ...
x = 900° -146° -122° -142° -140° -110° -142°
x = 98°

Answer: I do believe the answer is Y=-135
Step-by-step explanation: Input -3 in for X -3*3=-9*15=-135
Maria determined that these expressions are equivalent expressions using the values of x = 3 and x= 7 Which
statements are true? Check all that apply.
5+3x-2 and x + 2(x+1)+1
The expressions are only equivalent when evaluated with odd values
The expressions are only equivalent for x = 3 and x = 7
The expressions should have been evaluated with one odd value and one even value.
The expressions have equivalent values when X = 6.
When X=0, the first expression has a value of 3 and the second expression has a value of 4.
The expressions have equivalent values for any value of x.
When x= 10, both expressions have a value of 33

After getting 5 new rocks, George gave half of his rock collection to Susan. If George gave Susan 36 rocks, which equation could be used to determine how many rocks George started with?
C: 1/2(x+5)=36
Answer:
im not sure but ik u do 36x2=72-5=67 so thats how many rocks he had then he found 5 and gave away half leaving 36 bc 72/2=3 how you would write that i am not to sure but hope i helped in getting you closer to the answer.

Find the HCF of :32 48 64
Answer:
16
Step-by-step explanation:
The HCF of numbers is the highest common factor, which means it is the biggest number that is a factor of these three numbers.
We can find this by dividing all three numbers by very basic factors such as 2 and divide the remainder of the three numbers by another factor.
This process is shown here:
(32, 48, 64) / 2 = (16, 24, 32)
(16, 24, 32) / 2 = (8, 12, 16)
(8, 12, 16) / 2 = (4, 6, 8)
(4, 6, 8) / 2 = (2, 3, 4)
As you can see 2, 3 and 4 do not have any more common factors. So therefore the HCF of 32, 48 and 64 is 2x2x2x2, which equals to 16.

Really need help quick
Answer:
Total Number of times Spun = 1200
Key sentence: "Pr(Red) is same as Pr(Yellow).
Pr(Green)= 0.2
0.2 = x/1200
x= 0.2 x 1200
x = 240.
It landed on green 240 times
Pr(Brown) =0.54
0.54 = y/1200
y= 1200 x 0.54
y= 648.
Now
To get the Number of times it landed on Red and Yellow
You simply subtract that of Green and Brown from 1200 and divide this result by 2(Since Red and Yellow are have equal occurrence).
1200 – (648 + 240)
= 312.
312/2 = 156.
So It landed on Red and Yellow 156 times each.
Step-by-step explanation:
Red ----- 156times
Green -----240times
Brown ----- 648times
Yellow -----156times

Answer:
y = -4x + 5 is the equation of the line
Step-by-step explanation:
Let's find the y = mx + b
-3 = -4(2) + b
-3 = -8 + b

------------------
5 = b
c(ge + p) = n +j
Solve for c: C=
Answer:
[tex]c(ge + p) = n + j \\ \\ \frac{c(ge + p)}{(ge + p)} = \frac{n + j}{(ge + p)} \\ \\ { \boxed{ \boxed{c = \frac{n + j}{ge + p} }}}[/tex]
B is the midpoint of AC. AB=2x+4; BC=5x-11. Find X
Answer:
x=5
Step-by-step explanation:
AB and BC must be equal if B is a midpoint
Therefore
2x+4=5x-11
Simplify:
add 11 to both sides=
2x+15=5x
subtract 2x both sides:
3x=15
Divide
x=5
Answer:
x=5
Step-by-step explanation:
Since B is the midpoint you would need to form the equation like this:
[tex]2x+4=5x-11\\-2x+11 -2x+11\\15=3x\\x=5[/tex]

What value of t is the velocity greatest?
Answer:
t = 1
Step-by-step explanation:
the greatest velocity could be reached:
v' = 0
12 - 12t =0
or 12t =12
t = 12/12
t = 1
v=12t-6t^2
Find derivative of v
[tex]\\ \sf\longmapsto \dfrac{dv}{dx}[/tex]
[tex]\\ \sf\longmapsto \dfrac{d}{dx}12t-6t^2[/tex]
[tex]\boxed{\sf \dfrac{d(x^n)}{dx}=nx^{n-1}}[/tex]
[tex]\\ \sf\longmapsto 12-12t[/tex]
Let it be 0
[tex]\\ \sf\longmapsto 12-12t=0[/tex]
[tex]\\ \sf\longmapsto 12=12t[/tex]
[tex]\\ \sf\longmapsto t=\dfrac{12}{12}[/tex]
[tex]\\ \sf\longmapsto t=1s[/tex]
