In a recent golf match,Becky’s score was 5 less than Cathy’s score their combined score totaled 185 let b represent Becky’s score and c represent Cathy’s score which pair equation can be used to determine their scores
Answers
It says that b represents Becky’s score and c represents Cathy’s score.
Becky’s score was 5 less than Cathy’s score, its equation can be written as :-
b = c - 5
It says that their combined score totaled 185, its equation can be written as :-
b + c = 185
So, correct pair of equations is b = c - 5 and b + c = 185.
If Becky’s score was 5 less than Cathy’s, then we would write:
b = c - 5
If Becky’s and Cathy’s scores add up to 185, then we would write:
b + c = 185
These are the two equations:
b = c - 5
b + c = 185

B. Find the area of the triangle if 8 and 12 are a leg and hypotenuse.
Answers
where a and b are both legs of the triangle.
A) a = 8 inches ; b = 12 inches
A = (8in x 12in)/2 = 96/2 = 48 in²
B.) a = 8 inches ; b = ? ; hypotenuse = 12 inches
Pythagorean theorem is used to get the measurement of the hypotenuse. It can also be used to get the measurement of the missing leg.
a² + b² = c² ⇒ b² = c² - a²
b² = 12² - 8²
b² = 144 - 64
b² = 80
b = √80
b = 8.94
A = ab/2 ⇒ (8 inches * 8.94 inches)/2
A = 71.52 in² / 2
A = 35.76 in²

Answer:
(1/2)(10)(x + 15 + x) = (2/5)(10)(20 + x)
(1/2)(2x + 15) = (2/5)(x + 20)
5(2x + 15) = 4(x + 20)
10x + 75 = 4x + 80
6x = 5
x = 5/6
NB = 5/6
