Answer:

UMBC scored 10,14 and 12 one - point free throws, two point baskets and three point baskets respectively.

Step-by-step explanation:

Let's start defining the variables.

X : ''Number of 1 - point free throws''

Y : ''Number of 2 - point baskets''

Z : ''Number of 3 - point baskets''

UMBC scored a total of 74 points. Therefore,

X.1+Y.2+Z.3=74 (I)

Where X.1 represents the total points from 1 - point free throws.

Where Y.2 represents the total points from 2 - point baskets.

And finally Z.3 represents the total points from 3 - point baskets.

Reading the exercise, we can write two more equations :

Y=Z+2\\Z=X+2

Let's write Y and X in terms of Z

Y=Z+2 (II)

Z=X+2 ⇒ X=Z-2 (III)

Replacing (II) and (III) in (I) :

(Z-2).1+(Z+2).2+Z.3=74

Z-2+2Z+4+3Z=74

6Z+2=74\\6Z=72\\Z=12

We find that the variable Z is 12. Replacing this value in (II) and (III) ⇒

Y=12+2=14\\Y=14

X=12-2=10\\X=10

Finally, UMBC scored 10 baskets from 1 - point free throws,14 baskets from of 2 - point and 12 baskets of 3 - point.

We can verify by replacing X = 10 , Y = 14 and Z = 12 in equation (I) :

10.1+14.2+12.3=74\\10+28+36=74\\74=74

The length of a model car is 1/20 of the length of the actual car. If the model. is 8.7 inch long, how long is the actual car? E
madam [21]
This means that if the model is 1 in lengh then th ereal car is 20 times of that or 20 in legnth

so to find the answer, just multiply model by 20
8.7 =model
real=8.7 times 20=174
real car is 174 inches

12 inches=1 foot
conversion factor
1 ft/12in=1=convesion

so
174 times 1/12=14 and 6/12

the answer is 14 feet and 6 inches or 14.5 feet
