Answer:
Part A:
x+y= 95
x = y+25
Part B : 35 minutes
Part C : No
Step-by-step explanation:
Eric plays basketball and volleyball for a total of 95 minutes every day
x+y= 95
Where:
x =the number of minutes Eric plays basketball
y= the number of minutes he plays volleyball
He plays basketball for 25 minutes longer than he plays volleyball.
x = y+25
System:
x+y= 95
x = y+25
Replacing x=y+25 on the first equation:
(y+25) + y =95
Solving for Y
y+25+y =95
25+2y=95
2y=95-25
2y=70
y = 70/2
y = 35 minutes
Part C : No
if x = 35
x+y= 95
35+y =95
y= 95-35
y = 60 minutes
Replacing y=60 on the other equation:
x = y+25
35 = 60+25
35 ≠85

Answer:
Step-by-step explanation:
Given
Solving (a): NK
MK is a diagonal and NK is half of the diagonal. So:
Solving (b): JL
JL is a diagonal, and it is twice of NL.
Solving (c): KL
To solve for KL, we consider triangle KNL where:
and
Solving (d - h):
To do this, we consider triangle JKN
-- diagonals bisect one another at right angle
Alternate interior angles are equal. So:
Similarly:
So:
Simplify:
Solution ===> −7 + 12 − 3(50 − 4(2 + 3)) =========> -85
= 5 − 3(50 − 4(2 + 3))
= 5 − 3(50 − (4)(5))
= 5 − 3(50 − 20)
= 5 − (3)(30)
= 5 − 90
= −85
Answer ================> -85
Simplify:
1/3 + 6(2/3 - 1/6)^2
1/3 + 6(1/2)^2
1/3 + 6(1/4)
1/3 + 3/2
Answer =======> 11/6 =========> Decimal =======> 1.833333.....
Hope that helps!!!! : )
