Answer:
131.25= 17.50+8.75x is the equation
Step-by-step explanation:
solve it to find x
131.25=17.50+8.75x
(subtract 17.50 from both sides)
113.75=8.75x
(divide both sides by 8.75)

Answer = 4
10^2 = 100
8^2 = 64
100 + 64 = 164
180 - 164 = 16
Square root of 16 = 4
(3x − 5) − (4x + 6)
Pretend that there is a 1 in front of the first bracket.
Pretend that there is a -1 in front of the second bracket.
Multiply the first bracket by 1
(1)(3x)=3x, (1)(-5)=-5
Multiply the second bracket by -1
(-1)(4)=-4, (-1)(6)=-6
3x-5-4x-6
3x-4x-5-6 ( combine like terms)
-x-11
Answer: -x-11 or -11-x
