9 [1+345-(6-8 +48 x 23 -77​
melisa1 [442]

Answer:

1933

Step-by-step explanation:

9 x (1 + 345) - 6 - 8 + 48 x 23 - 77

Use BODMAS method to solve these type of equation

B - Brackets

O - Power

D - Division

M - Multiplication

A - Addition

S - Subtraction

_________________________________________________________

Brackets - 1 + 345 = 346

Multiplication

9 x 346 = 3114

48 x 23 =  1104

Lets rewrite the equation now

3114 - 6 + 1104 - 77

Addition

6 + 1104 = 1110

Subtraction

3114 - 1104 = 2010

2010 - 77 = 1933

Answer = 1933

Hope you understand

If you had a bank that offered 6.1% interest and compounded money 4 times a year, how many years would go by until you could tur
Verdich [7]

Answer:

t = 11.45 years

Step-by-step explanation:

A = p(1+r/n)^nt

A = future value = $12000

P = present value = $6000

n = number of periods = 4

r = interest rate = 6.1% = 0.061

t = number of years = ?

t = log(A/P) / n[log(1 + r/n)]

= log(12000/6000) / 4[log(1+0.061/4)]

= log(2) / 4[log(1 + 0.01525)]

= 0.3010 / 4[log(1.01525)]

= 0.3010 / 4(0.00657)

= 0.3010 / 0.02628

= 11.45 years

ANSWER ASAP <br> Write an equation of a line that passes through the points (2,3) and (2,-6).
Agata [3.3K]
1st you need to fine the slope using 

S = y2-y1/x2-x1

S = -6 - 3/2-2

S = -9/0

S = Undefined 

when we have undefined slope the equation would be a vertical lines. 

Thus the equation would be the x value of the point 

Thus the equation is x = 2
