X = Brandon's age
3x - 34 = x + 2
2x = 36
x = 18
Jason is 20 years old.
It’s option number 1
True me it’s hard to explain but I’m 100% sure it’s number 1
164.38 = (1 x 100) + (6 x 10) + (4 x 1) + (3/10) + (8/100)
Answer:
428.97
Step-by-step explanation:
The first step is to find the sales tax
tax = original price * tax rate
tax = 395 * 8.6%
= 395*.086
=33.97
Now we need to add this to the original price
new price = original price + tax
=395+ 33.97
=428.97
Answer:
Step-by-step explanation:
x^2 - 6x - 40 = 0.....get the -40 to the other side
x^2 - 6x = 40....now take half of ur x term (6)....so its 3...then square it (3^2 = 9)...now add 9 to both sides
x^2 - 6x + 9 = 40 + 9
(x - 3)(x - 3) = 49
(x - 3)^2 = 49...take sqrt of both sides, eliminating the ^2
x - 3 = sqrt 49
x = 3 (+ - ) 7
x = 3 + 7 = 10 or x = 3 - 7 = -4
so x = 10 or x = -4
