Answer:
x= -7
Step-by-step explanation:
1/2(4-6x)=23
Take1/2 of the numbers in the (). It will be 2-3x.
2-3x=23 subtract 2 from both sides to get x by itself
-3x=21 now divide the 21 by -3
x= -7
Answer: The future value of the investment after 2 years is $807.8
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents the principal or amount invested.
R represents interest rate
T represents time in years
I = interest after t years
From the information given
T = 2 years
P = $700
R = 7.7%
Therefore
I = (700 × 7.7 × 2)/100
I = 10780/100
I = 107.8
The total amount in the account after 2 years would be
700 + 107.8 = $807.8
Answer: D) 155
Step-by-step explanation:
let <A, <B,<C are three angles in a triangle.
sum of the three angles in a triangle is 180degree.
<A+<B+<C=180
130+<B+<C=180 since one angle is given
<B+<C =180-130
<B+<C=50
(<B+<C)/2=25----(1)after bisecting sum of the angles
required angle =180-25=155
d is correct answer
