Answer:
66
Step-by-step explanation:
One way of solving this is to first add 12 to get the number to 0. Then add another 54 to get to 54 degrees. Then you can add these two numbers together to get 66.

Answer:
q= -10
Step-by-step explanation:
1. add 3 to both sides : -q=10
2. divide by -1
3. 10 / -1 = -10
q=-10
Answer:
Equal sides = 6cm each
Unequal side = 12cm
Step-by-step explanation:
Perimeter of a triangle = side a + side b + side c
Let
Side a = side b = x
Side c = 2x
Perimeter of the triangle=24cm
Perimeter of a triangle = side a + side b + side c
24 = x + x + 2x
24 = 4x
Divide both sides by 4
24 / 4 = 4x / 4
6 = x
x = 6
The equal sides = x = 6cm each
The unequal side = 2x
= 2(6)
= 12cm
Check:
Perimeter of a triangle = side a + side b + side c
= 6cm + 6cm + 12cm
= 24cm
Answer:
The Answer is: Lower Level seats = 150. Upper level seats = 200.
Step-by-step explanation:
Start with two known equations:
1 - the number of Lower Level times 35 + the number of Upper level times 25 = the total dollar amount of $10,250.
35L + 25u = 10250
The number of both types of tickets = 350
L + u = 350
Solve for u:
u = 350 - L
Substitute and solve for L, Lower level seats:
35L + 25(350 - L) = 10250
35L + 8750 - 25L = 10250
10L + 8750 = 10250
10L = 1500
L = 150
There are 150 Lower Level seats.
u = 350 - L
Subtract to get the number of upper level seats:
u = 200
Proof:
35(150) + 25(200) =
$5,250 + $5,000 = $10,250
