Step-by-step explanation:
to find the sum of nth term
equation is
n/2 ( 2a + (n-1)d) where a is the 1st term and d is the common difference
5/2 ( 120 +( 4 × 31))
5/2 ( 120 + 124)
5/2 × 244
5 × 122 <em>dividing</em><em> </em><em>2</em><em>4</em><em>4</em><em> </em><em>by</em><em> </em><em>2</em>

You could draw a circle for the first two and split it into 4. Shade in 1 section and label 25%. Then say that 25% is 1/4 of the circle. For 50%, draw another circle, and split it into 4 again. This time, shade in 2 sections. Label as 50%. Then say that 50% is 1/2 of a circle. Draw another circle and split it into 6 sections. Label as 150%. Then label that each section is 25% and a circle split in 6 at each section at 25% would be 150% for the whole circle.
-3/4(x+2)=6
-3/4 is turned into a decimal, -0.75
-0.75(x+2)=6 distribute -0.75 to x and 2 (multiply)
-0.75x-1.5=6 add -1.5 under 6
-0.75x=7.5 divide -0.75 on both sides
-0.75x/-0.75 = 7.5/0.75
x=10
The formula for the money multiplier is :
1/ Reserve rate
so, the answer would be :
1/0.05
