4 +5 = 9 and 12 + 3 =15 and there is more than this
hope I helped
700-620=80 so 80 reading questions
The Line PQ is cut half equally by point T. MEANING PT=TQ!!! So first, write out the equation.
PT = TQ
20?5x+3=7x-9
21?4x-6=3x+4
22?7x-24=6x-2
The question asks you to find the value of PT, but you’ll have to find the value of x first.
x=6
x=10
x=22
And then just just plug in x in just the PT equation.
5(6)+3= 33
4(10)-6= 34
7(22)-24= 130
and there you have it
20?=33
21?=34
22?=130
Answer:
2
Step-by-step explanation:
Answer: y = -1, y = 6 (choice D)
===========================================================
Work Shown:
y - (6/y) = 5
y*(y - (6/y)) = y*5 <<--- see note 1 below
y^2 - 6 = 5y
y^2 - 5y - 6 = 0
(y+1)(y-6) = 0 <<--- see note 2 below
y+1 = 0 or y-6 = 0
y = -1 or y = 6 which are the two answers
note 1: I multiplied both sides by y to clear out the fraction (the LCD is y)
note 2: I factored the left side by asking myself "what two numbers multiply to -6 and add to +5?" the answer to that question is +1 and -6 which helps lead to the factorization. An alternative route instead factoring is to use the quadratic formula
