BARSIC [14]
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

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

x+y=54 ----> equation A

x=y+4 ----> equation B

substitute equation B in equation A and solve for y

(y+4)+y=54\\2y=54-4\\2y=50\\y=25

Find the value of x

x=25+4=29

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

x+y=44 -----> equation A

x=y-15 ----> equation B

substitute equation B in equation A and solve for y

(y-15)+y=44\\2y=44+15\\2y=59\\y=29.5

Find the value of x

x=29.5-15=14.5

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
