Multiplied by the cross
4/15 = x /75
15•x=4•75
15x=300
x= 300 : 15
x=20
t/9 = 35/6
9•35 = t•6
315 =6t
315 : 6 = t
52,5 = t
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
