Answer:
d = 2r
Step-by-step explanation:
r = price of a regular ticket
d = price of a 3D ticket
The cost of the 3D ticket was double the cost of the regular admission ticket
d = 2r
The equation that represent the relationship between the two types of tickets is d = 2r
Answer:
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180 degrees
so
70 + 35 + x = 180 add like terms
105 + x = 180 subtract 105 from both sides
x = 75
Answer:
c. y=-3x
Step-by-step explanation:
Plug in x=0 and y=0.
0=-3(0)
0=0...the origin
Answer
Find out the how much did the height of the tree sapling increases.
To proof
Let us assume that the height of the tree sapling increases be x.
As given
The high every tree sapling was 3.15 inches last year
this year the high is 5.38 inches.
than the equation is become in the form
x = 5.38 - 3.15
x = 2.23 inches
Therefore the height of the tree sapling increases be 2.23 inches.
Hence proved
Yard to square yard
example: 1yard*1 = 1square yard so 6*6=36 square yards. 7*7=42
36*2.90=104.40
42*2.90=121.8
104.40+121.8=$226.20
