Step-by-step explanation:
With the given information, we can create several equations:
120 = 12x + 2y
150 = 10x + 10y
With x being the number of rose bushes, and y being the number of gardenias.
To find the values of the variables, we can use two methods: Substitution or Elimination
For this case, let us use elimination. To begin, let's be clear that we are going to be adding these equations together. Therefore, in order to get the value of one variable, we must cancel one of them out - it could be x or y, it doesn't matter which one you decide to cancel out. Let's cancel the x out:
We first need to multiply the equations by numbers that would cause the x's to cancel out - and this can be done as follows:
-10(120 = 12x + 2y)
12(150 = 10x + 10y) => Notice how one of these is negative
Multiply out:
-1200 = -120x - 20y
+ 1800 = 120x + 120y => Add these two equations together
---------------------------------
600 = 100y
Now we can solve for y:
y = 6
With this value of y known, we can then pick an equation from the beginning of the question, and plug y in to solve for x:
120 = 12x + 2y => 120 = 12x + 2(6)
Now we can solve for x:
120 = 12x + 12 => 108 = 12x
x = 9
So now we know that x = 9, and y = 6.
With rose bushes being x, we now know that the cost of 1 rose bush is $9.
With gardenias being y, we now know that the cost of 1 gardenia is $6.
Answer:
The greatest common factor is 6.
Step-by-step explanation:
Greatest common factor is 6. If you use the distributive property then the answer would be 6(4) + 6(6) or 6(4+6). Then you distribute the 6 to each digit and should get 24+36.
Answer:
x = 5.
First angle = 20°, Second angle = 85°, Third angle = 75°
Step-by-step explanation:
The first angle of the triangle = (4 x)
The second angle of the triangle = (6x + 55)
The third angle of the triangle = (9x + 30)
By ANGLE SUM PROPERTY of a triangle:
First angle + Second angle + Third angle = 180°
⇒ (4 x) + (6x+55) + (9x+30) = 180°
or, (4x + 6x + 9x) + ( 55 + 30) = 180°
or, 19x = 180 - 85
or, 19 x = 95 ⇒ x = 95 /19 = 5
or, x = 5
Hence, first angle of the triangle = (4 x) = 4 x 5 = 20°
Second angle = ( 6x + 30) = 6(5) + 55 = 85°
Third angle = (9x + 30 = 9(5) + 30 = 75°
