Answer:
Cost of 1 rose bush = x = $5
Cost of 1 geraniums = y = $2
Step-by-step explanation:
DeShawn and Mike each improved their yards by planting rose bushes and geraniums. They bought their supplies from the same store.
Let us represent:
Cost of 1 rose bush = x
Cost of 1 geraniums = y
DeShawn spent $13 on 1 rose bush and 4 geraniums.
x + 4y = 13..... Equation 1
x = 13 - 4y
Mike spent $56 on 10 rose bushes and 3 geraniums.
10x + 3y = 56....... Equation 2
We substitute 13 - 4y for x in Equation 2
10(13 - 4y) + 3y = 56
130 - 40y + 3y = 56
Collect like terms
- 40y + 3y = 56 - 130
-37y = -74
y = -74/37
y = $2
Solving for x
x = 13 - 4y
x = _13 - 4 × $2
x = $13 - $8
x = $5
Therefore,
Cost of 1 rose bush = x = $5
Cost of 1 geraniums = y = $2
The volume (V) of prism is the product of the area (A) of the base and its height (h). The area of the square base is the square of its width, 3 cm.
144 cm³ = (3 cm)² x h
The value of h from the equation is 16. Therefore, the height of the prism is 16 cm.
Answer:
Simplifying
5x + 12 = -13
Reorder the terms:
12 + 5x = -13
Solving
12 + 5x = -13
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-12' to each side of the equation.
12 + -12 + 5x = -13 + -12
Combine like terms: 12 + -12 = 0
0 + 5x = -13 + -12
5x = -13 + -12
Combine like terms: -13 + -12 = -25
5x = -25
Divide each side by '5'.
x = -5
Simplifying
x = -5
