Answer:
equation: 3.5x=31.5
number of hours: 9
Step-by-step explanation:
31.5/3.5=9
Therefore,
x=9, x=number of hours, number of hours=9
<em>Step 1: Subtract x from both sides. </em>
1/3x +4− x =x −2− x
= -2/3 x +4 = -2
<em>Step 2: Subtract 4 from both sides</em>.
-2/3x + 4− 4 =−2− 4
-2/3x = -6
<em>Step 3: Multiply both sides by 3/(-2).</em>
( 3/-2 ) * (-2/3x ) = (3/-2) * (-6)
= 9
So , X=9
13.9%.
7.2 x 10^9 = 7,200,000,000.
Since 1 billion = 1,000,000,000 out of these 7,200,000,000 do not have access to clean water, we find the percent by taking:
1,000,000,000/7,200,000,000 = 10/72 = 13.9%
Answer:
$25,740
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 23400 × 0.05 × 2 = 2340
I = $ 2,340.00
The simple interest accumulated
on a principal of $ 23,400.00
at a rate of 5% per year
for 2 years is $ 2,340.00.
