Answer: the amount of interest that she would earn is $192.
Step-by-step explanation:
We would apply the formula for determining simple interest which is expressed as
I = PRT/100
Where
I represents interest paid on the amount of money deposited.
P represents the principal or amount of money deposited.
R represents interest rate on the deposit.
T represents the duration of the deposit in years.
From the information given,
P = $800
R = 4%
T = 6 years
Therefore,
I = (800 × 4 × 6)/100
I = $192
2/3x-1/5=x-1
Add similar elements 23x-15=8x
Subtract x from both sides 8x-x=x-1-x
Simply 7x=-x
Divide both sides by 7 7x = -1
__ __. *Simply: x=-1/7
7 7
Answer:
<em>3. x = 8</em>
<em>4. lines r and s</em>
Step-by-step explanation:
3.
The angles shown are same side interior angles, so they are supplementary. Their measures add to 180 deg.
5x + 10 + 130 = 180
5x + 140 = 180
5x = 40
x = 8
4.
Lines r and s are cut by a transversal, line l. Angles 3 and 6 are alternate interior angles. Lines r and s are parallel.
Answer:
y = -4/3x - 1
Step-by-step explanation:
(0,-1) and (4,2)
3/4 is the slope
-4/3 is its perpendicular
y +1 = -4/3(x - 0)
y = -4/3x - 1
