Answer:
Step-by-step explanation:
The two inside angles will sum to 180°.
The top to angles are equal.
Think about this as what if both of the parallel lines were intersected by a perpendicuar line. Every angle would be a right triangle 90°. The inside angles will sum to 180° and the opposite angles are again equal.
(2x + 18) + (8x + 12) = 180
10x + 30 = 180
10x = 150
x = 15
-------------------------
(3y - 18) = (8x + 12) x = 15
(3y - 18) = (8(15) + 12)
(3y - 18) = (120 + 12)
(3y - 18) = 132
3y = 132 + 18
3y = 150
y = 50
Answer:
Monthly deposit= $323.78
Step-by-step explanation:
Giving the following information:
Future Value (FV)= 12,000*0.7= $8,400
Number of periods (n)= 2*12= 24
<u>We weren't provided with the interest rate, suppose an annual interest rate of 8%.</u>
Interest rate= 0.08/12= 0.00067
<u>Now, to calculate the monthly deposit, we need to use the following formula:</u>
<u></u>
FV= {A*[(1+i)^n-1]}/i
A= monthly deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (8,400*0.0067) / [(1.0067^24) - 1]
A= $323.78
