Answer:
p=228/5
Step-by-step explanation:
2/3p-7=1/4p+12
12(2/3p-7)=12(1/4p+12)
8p-84=3p+144
5p-84=144
5p=228
p=228/5
Check:
2/3(228/5)-7=1/4(228/5)+12
30.4-7=11.4+12
23.4=23.4

Step-by-step explanation:
Convert to twelfths. Then subtract.
Change 3/4 to 9/12 and 1/3 to 4/12.
4/12 - 9/12 = -5/12

(16.5+1.5n)°(12+2n)°
Answer:
1.7n +28.5
Step-by-step explanation:
you compare like terms first
1.5n add it to 2n
it will equal to 1.7
then add 16.5 to 12
it will equal to 28.5
Your new equation will be
1.7n+ 28.5 if it was equal to something let's say it was equal to 180 as an example:
your equation will be
1.7n + 28.5= 180
-28.5= -28.5
1.7n= 151.5 you would divide it
it would equal 89.1 and change.
Kari wants to measure the height of a tree. She walks exactly 90 feet away from the base of the tree and looks up to the top of it. The angle from the ground to the top of the tree is 32 degrees. This particular tree grows at an angle of 85 degrees with respect to the ground rather than vertically. How tall is the tree to the nearest tenth of a foot? Enter a number answer only.
Answer:
this is a Sin(), Cos() and Tan() function problem. use the Mnemonic (new-monic) SOH CAH TOA (soo caw tow ah ) to remember which function sin() cos() or tan() to use.. :) these types of problems are pretty confusing, Use that Mnemonic to keep the functions in order
Step-by-step explanation:
since we know the distance to the tree.. and we know the angle and we have a formula TOA to figure out the one pieces of info we don't know ... use TOA that tells us our formula.. TOA(Ф)=Opp / Adj where Tan(Ф) is using Ф= to our angle of 32 degrees ( remember Ф can be in degrees or radians, its in degrees for this problem) Adj = the Adjacent side of the triangle from the known angle.. the 32 degree angle , Opp = the Opposite side of the triangle formed by the imaginary lines from Kari to the base of the tree and from Kari to the top of the tree.. and then the tree , from it's base to it's top... we know the angle and the Adj side of that triangle so we can figure out that last part of TOA by saying Tan(Ф)=Opp/ Adj .... or say Tan(32)= Opp / Adj ⇒ Tan(32)=Opp / 90 ⇒ Tan(32) *90 = Opp this will be the height from the ground to the top of the tree.. but.. the tree is at an angle , keep in mind... sooo Tan(32)*90=56.238 feet now take the new triangle that we know one side to... from the ground to the height of the tree.. in a vertical line from the ground to a point at 56.238 feet .. that is the Adj side of this new triangle.. the tree is on the Hypotenuse of this new trialge, which we want to find. we know the Adj side we know the angle to find the Hypotenuse use CAH , from our Mnemonic at the top, the Mnemonic is really important b/c keeping track of which part goes where in the triangles is pretty confusing. Cos(5)=Adj / Hyp ⇒ Cos(5)=56.238 / Hyp ⇒56.238 / Cos(5)= Hyp = 56.453 feet :) that's how tall that tree is , lets chop it down :P and blame it on George Washington :P The tree, to the nearest 10th of a foot, is 56.5 feet

Ingrid and Harish were trying to solve the equation:
22 - 3x = x + 1
Ingrid said, "First, I'll subtract x from both sides so I have a? - 4x = 1. Then I can solve by completing the
square. If I add 4 to each side, I can rewrite the equation as (x - 2)² = 5."
Harish said, “I'll isolate the xạ term by adding 3x to both sides of the equation. Then I'll solve by taking the
square root."
Whose solution strategy would work?
Answer:
Only Ingrid's equation is correct
Answer:
Only Ingrid’s solution works
TJ is think of a number which he calls n he finds 1/3 of the number
Answer:
Step-by-step explanation:
Let the number TJ thinks of be n.
If he finds 1/3 of the number, the expression that models this situation is expressed as:
1/3 of n
= 1/3 * n
= n/3
hence the expression that models the scenario is n/3
Answer:
1/3n-5

3. In the same opera theater personal balcony sections with three rows of seating are being mapped as well. In
these sections there must be an odd number of seats in each row and each row must have two more seats
than the one before it. The last stipulation is that the front row must have one quarter the total seats in the
back 2 rows combined. How many seats will be in each row?
Answer:
Number of seats in first row = 2
Number of seats in 2nd row = 4
Number of seats in 3rd row = 6
Step-by-step explanation:
Let's say number of seats in first row is x.
Now we are told that each row must have two more seats
than the one before it.
Thus, the remaining 2 rows have;
(x + 2) and (x + 4) seats respectively.
We are told that that the front row must have one quarter the total seats in the
back 2 rows combined.
Thus;
x = ¼((x + 2) + (x + 4))
Multiply both sides by 4 to give;
4x = x + 2 + x + 4
4x = 2x + 4
4x - 2x = 4
2x = 4
x = 4/2
x = 2
Thus;
Number of seats in first row = x = 2
Number of seats in 2nd row = (x + 2) = 2 + 2 = 4
Number of seats in 3rd row = (x + 4) = 2 + 4 = 6

If the function 5x + y = 1 has the domain {-2, 1,6}, then what is the corresponding range?
O A.
{-9, 6, 31}
B. {9, -6, -31}
C. {-11, 4, 29}
D. {11, -4,-29}
Answer:
D, R: {11, -4, -29}
Step-by-step explanation:
According to the given set of domains, the corresponding range is found by substituting the x values into the equation and solving for y.
i.e {-2} -> 5x + y = 1, -10 + y = 1, y = 11
{1} -> 5x + y = 1, 5 + y = 1, y = -4
{6} -> 5x + y = 1, 30 + y = 1, y = -29

Answer:
Its's $3 for an adult ticket and $1 for a student ticket
Step-by-step explanation:
Three watches and five lamps cost $176 in all. Five watches and three lamps cost $208 in all. What is the cost of one lamp?
$200/5 lamps= $40 per lamp
Final answer: $40
Using the elimination principle, the cost of one lamp is $16
Let :
watches = a Lamps = b3a + 5b = 176 - - - - (1)
5a + 3b = 208 - - - (2)
Multiply (1) by 5 and (2) by 3
15a + 25b = 880 - - - - (3)
15a + 9b = 624 - - - - - (4)
Subtract (3) and (4)
16b = 256
b = (256 ÷ 16)
b = $16
Therefore, the cost of one lamp is $16
