Answer:
8 years.
Step-by-step explanation:
The simple interest formula is principal × rate (as a decimal) × time = interest. In this question, you want to find the time.
First, plug in your numbers. 350 × .055 × t = 154. Then, to find t, divide to get t one side.
t = 154 / 350 × .055
Then solve.
350 × .055 is 19.25. 154 / 19.25 is 8.
So, your answer is 8 years.
154/350*.055 = t
F ( x ) = x + 4
x = 3 p
f ( 3 p ) = 3 p + 4
Answer. D )
The ordered pair is:
( x, y ) = ( 3 p, 3 p + 4 )
Thank you.
Answer:
1. c
2.d
Step-by-step explanation:
It should take around 37 minutes.
The first given equation is:
4x + 3y = 6
which can be rewritten as:
2(2x) + 3y = 6 .............> equation I
The second given equation is:
2x + 2y = 5
which can be rewritten as:
2x = 5 - 2y ........> equation II
Substitute with equation II in equation I to get the value of y as follows:
2(5-2y) + 3y = 6
10 - 4y + 3y = 6
-y = 6-10 = -4
y = 4
Substitute with the y in equation II to get x as follows:
2x = 5 - 2y
2x = 5 - 2(4)
2x = 5 - 8 = -3
x = -3/2
From the above calculations:
x = -3/2
y = 4
