Answer:
Part 3) Miguel scored 29 points and Alonzo scored 25 points
Part 4) Morgan's age is 14 1/2 years and Mr Santos' age is 29 1/2 years
Step-by-step explanation:
Part 3) Let
x ----> the number of points that Miguel scored
y ---> the number of points that Alonzo scored
we know that
----> equation A
----> equation B
substitute equation B in equation A and solve for y
Find the value of x
the solution is the point (29,25)
That means ----> Miguel scored 29 points and Alonzo scored 25 points
Part 4) Let
x ----> Morgan's age
y ---> Mr Santos' age
we know that
-----> equation A
----> equation B
substitute equation B in equation A and solve for y
Find the value of x
the solution is the point (14.5,29.5)
That means ----> Morgan's age is 14 1/2 years and Mr Santos' age is 29 1/2 years
-0.15 is the correct answer I suppose!

Look at the graph and you can see that 1 week later the plant grew 2 inches. if you look at the other choices it is false because it didn't corresponding to the graph.
Answer:
Step-by-step explanation:
Since x represents the length in feet, and the width is 2 ft shorter than 3 times the length, the width is 3x-2.
The perimeter is twice the sum of length and width, so we can write the equation ...
76 = 2(x + (3x-2))
38 = 4x -2 . . . . . divide by 2, simplify
40 = 4x . . . . . . . .add 2
10 = x . . . . . . . . . the length of the garden is 10 ft
The width of the garden is ...
3·10 -2 = 28 . . . feet
The width of the garden is 28 feet.
