Answer:
446
Step-by-step explanation:
9n-4
9(50)-4
450-4
=496
Two equations two unknowns
1. 3a + 6s = 60
2. 5a + 3s = 44
solve for a in 1, a = (60 - 6s)/3 = 20 - 2s
substitute into 2
5(20 - 2s) + 3s = 44
solve for s
s = 8
substitute in 1
a = 4
Answer:
-4,-5
Step-by-step explanation:
first set the equation equal to 0, v^2+9v+20, factor v^2+4v+5v+20, v(v+4) 5(v+4), so the 2 factors are (v+5) and (v+4), set both equal to that 0. v+5=0 v=-5 and v+4=0 v=-4, so the answer is -4 and -5
Answer:
see explanation
Step-by-step explanation:
Substitute n = 1 into each of the expressions
8n + 6
= 8(1) + 6
= 8 + 6
= 14
2(4n + 3)
= 2(4(1) + 3)
= 2(4 + 3)
= 2(7)
= 14
14n
= 14(1)
= 14
