Answer:
(1.5, 3)
Step-by-step explanation:
Given the 2 equations
2x + 3y = 12 → (1)
y = x + 1.5 → (2)
Substitute y = x + 1. 5 into (1)
2x + 3(x + 1.5) = 12 ← distribute and simplify left side
2x + 3x + 4.5 = 12
5x + 4.5 = 12 ( subtract 4.5 from both sides )
5x = 7.5 ( divide both sides by 5 )
x = 1.5
Substitute x = 1.5 into (2) for corresponding value of y
y = 1.5 + 1.5 = 3
Solution is (1.5, 3)
Answer: 12.5
Step-by-step explanation:
1/2 of 25 is 12.5 since when added together they create 25
Step-by-step explanation:
y and x are proportional:
y = kx
When x is 29, y is 275.5.
275.5 = 29k
k = 9.5
y = 9.5x. When y is 408.5:
408.5 = 9.5x
x = 43
A relationship that can be modeled as a line that passes through the origin (y = kx) is a proportional relationship.
