Answer: 8
Step-by-step explanation:
Since AB is a tangent, angle CAB is a right angle. Thus, by the Pythagorean theorem, 
Answer:
y =
or -3.571
x =
or 1.429
Step-by-step explanation:
x - y = 5
x = 5 + y
Solve for y:
y = -6x + 5
y = -6(5 + y) + 5 Substitute x with 5 + y
y = -6(5) - 6y + 5
y = -30 - 6y + 5
y + 6y = -30 + 5
7y = -25
y =
or -3.571
Solve for x:
x = 5 + y
x = 5 + -25/7
x =
or 1.429
Let number be x and x+13
Then x+x+13=15 (A/q)
2x+13=15
2x=2
X=1
:. X+13= 14
Two numbers are 1 And 14
Answer:
<h2>
6.75+1.25x=31.75</h2>
Step-by-step explanation:
let x be the number of refils
also given is that the cost of one refill is $1.25
hence the total refil will be 1.25x
given that the cost of a mug is $6.75
6.75+1.25x=31.75
therefore the expression that can be used to solve for the number of refills is
6.75+1.25x=31.75
