Im begging someone to please please help me, like please! its just 3 problems :( 1.The sum of three consecutive numbers minus 12 is 75
2.The Sum of two consecutive odd numbers plus eighteen is 170
3.Noah goes to the bank to deposit $5,000 in a savings account. The teller offers Justin a choice. He can either put his money in a checking account which compounds 5% annually or he can get an account which compounds his interest by 0.5% monthly. How much will he have in both accounts after 1 year, 3 years, and 10 years? Which option should Justin Pick?

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
