Step-by-step explanation:
-288 points (the total) divided by the player's 9 turns equals -32. This means that they got negative 32 points on average every round.
Answer:
20
Step-by-step explanation:
u-t = 2
u+t= 5
(u-t) (u²-t²)
(u-t) (u-t) (u+t) (a²-b²= (a+b) (a-b))
put the values
(2)(2)(5)
=20
To find the ratio of centimeters to meters you need to divide 66 by 33 to get 2.
Then multiply 2727 by 2 to get 5454.
The answer is <span>b.3x + 15 = 55 - x
</span>
x - Jill's present age
y - dad's present age
<span>In 5 years, Dad will be three times as old as his daughter Jill will be then:
y + 5 = 3(x + 5)
</span><span>The sum of their present ages is 50:
x + y = 50
We have the system of two equations now:
</span>y + 5 = 3(x + 5)
x + y = 50
Let's rearrange the second equation:
If: x + y = 50
Then: y = 50 - x
Now, substitute y from the second equation (y = 50 - x) into the first one:
y + 5 = 3(x + 5)
50 - x + 5 = 3(x + 5)
50 + 5 - x = 3*x + 3*5
55 - x = 3x + 15
Rearrange it a bit:
3x + 15 = 55 - x
Therefore, the correct choice is b.
