Answer:
Step-by-step explanation:
1. 6x + 10 = 6x - 8
10≠-8
no solution
2. 6x + 8 = 2x - 6
4x + 8 = -6
4x = -14
x = -14/4= -7/2 one solution
3. 9x - 27 = 9x - 27
0 = 0 All real no. infinitely many solution
Answer:
11/20
Step-by-step explanation:
Finding the common denominator, which is 20, we convert 1/5 into 4/20 and 1/4 into 5/20. Adding those up, the remainder when subtracted from 1, the total, is 11/20.
Answer:
By applying Pythagoras theorem
Answer is √[109] inch
12oz(8in^3orange/1.25oz)=76.8 in^3 of oranges...
Vo=(4p(3.5/2)^3)/3=22.45 in^3 per orange...
76.8 in^3(orange/22.45 in^3)=3.42 oranges...
Round down to 3 oranges.
Answer:
Step-by-step explanation:
a² - b² = (a +b)(a - b)
9x² - 4 = (3x)² - 2²
= (3x + 2 )(3x - 2)
