Answer:
steps below
Step-by-step explanation:
√576 = √64*9 = √(2)⁶*(3)² = 2³*3 = 24
√15876 = √4*81*49 = √2²*3⁴*7² = 2*3²*7 = 126
3/4+1/3=9/12+4/12=13/12 of an hour
13/12= 1 1/12
41.8 rounded to the nearest tenth
1 gallon= 8.345 pounds
11.81 gallons= ? Ibs
11.81*8.345= 98.5 Ibs (99)
Answer:
The solution is (3/8, -7/8).
Step-by-step explanation:
y = −5x + 1
y = 3x − 2
Since the 2 expressions in x are both equal to y :
−5x + 1 = 3x - 2
-5x - 3x = -2 - 1
-8x = -3
x = 3/8.
So y = 3x - 2
= 3(3/8) - 2
= 9/8 - 2 = -7/8.
