Answer:
(3, 4 )
Step-by-step explanation:
3x - y = 5 → (1)
x + y = 7 → (2)
adding the 2 equations term by term will eliminate y
4x + 0 = 12
4x = 12 ( divide both sides by 4 )
x = 3
substitute x = 3 into either of the 2 equations and solve for y
substituting into (2)
3 + y = 7 ( subtract 3 from both sides )
y = 4
solution is (3, 4 )
Answer:
It will take her 20 more minutes
Step-by-step explanation:
24=60 minutes
32=x
60/24=2.5
32(2.5)=80
32=80 minutes
80-60=20
I believe it is 27%. 54/200=27/100=27%
Answer:
The 25th term of the sequence is 147
Step-by-step explanation:
For an nth term in an arithmetic sequence
U(n) = a + (n - 1)d
Where
n is the number of terms
a is the first term
d is the common difference
From the above sequence
a = 3
d = 9 - 3 = 6
So the 25th terms for the sequence is
U(25) = 3 + ( 25 - 1) 6
= 3 + 24(6)
= 3 + 144
The final answer is
= 147
Hope this helps you.
