Took test. I see the question you was trying to do.
The first term of an AP can be defined as T1 i.e. n=1. According to the given equation,. T1=a=2(1)+9=11.
Answer:
89
Step-by-step explanation:
Money spent + money left over = total money
money spent + 9 = 30
We don't know the price of each shirt, so let x = price of 1 shirt.
Then, 3 shirts cost 3 times as much as x, or 3x.
She spent 3x.
3x + 9 = 30
Answer:
x = 19
Step-by-step explanation:
These are vertical angles, which means that the angle measurements are going to be the same. Set the two angle measurements equal to each other:
3x - 3 = 6(x - 10)
Simplify. First, distribute 6 to all terms within the parenthesis:
3x - 3 = 6(x - 10)
3x - 3 = 6(x) - 6(10)
3x - 3 = 6x - 60
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 3 and subtract 6x from both sides:
3x (-6x) - 3 (+3) = 6x (-6x) - 60 (+3)
3x - 6x = -60 + 3
-3x = -57
Isolate the variable, x. Divide -3 from both sides:
(-3x)/-3 = (-57)/-3
x = -57/-3 = 57/3 = 19
x = 19 is your answer.
