Answer:
X= 31
Step-by-step explanation:
13x- 15= 12x+ 16
-12x -12x
x- 15= 16
+15 +15
x= 16+ 15
x= 31
At least $73.50 for 7x3 is 21 gallons and 10.50x7 is $73.50
Answer:
x = 4.1 cm
Step-by-step explanation:
To find x, apply pythagorean theorem, which is given as:
c² = b² + a²
Where,
c = 8.8 cm
b = ½(15.6) = 7.8 cm
a = x
Plug in the values
8.8² = 7.8² + x²
77.44 = 60.84 + x²
Subtract both sides by 60.84
77.44 - 60.84 = x²
16.6 = x²
Take the square root of both sides
√16.6 = x
x = 4.07430976
x = 4.1 cm (nearest tenth)
Answer:
All real numbers except 6
Yeah I'm pretty sure that's the simplest form
