Let's start by solving the first equation.
a) -3 = 7 + 2t/3
To begin simplifying this equation, we should multiply both sides by 3 to get rid of the denominator on the right side of the equation.
-9 = 7 + 2t
Next, we should subtract 7 from both sides to cancel out the 7 on the right side.
-16 = 2t
Finally, we should divide both sides by 2.
t= -8
Now let's move on to the next equation.
b) 4(5x-2) = 7(2x+3)
Let's use the distributive property to get rid of the parentheses and their coefficients.
20x-8 = 14x + 21
Now, lets subtract 14x from both sides of the equation.
6x - 8 = 21
Next, let's add 8 to both sides of the equation.
6x = 29
And divide both sides by the coefficient of x, which is 6.
x = 29/6 or 4 5/6
Now for the last equation.
C) 2x - 6 = 20 - 2.5x
First, we should add 2.5x to both sides to cancel out the -2.5x on the right side of the equation.
4.5x - 6 = 20
Now, let's add 6 to both sides to get the variable term alone.
4.5x = 26
Finally, we should divide both sides by 4.5 to get x by itself.
x = 5 7/9
Hope this helps! :)

Answer:
48oz for $1.39
Step-by-step explanation:
if you divide 48 by 1.39 and you get 34.5323741007
if you divide 32 by .89 you get 35.9550561798
and 34.5323741007 is less than 35.9550561798 and you want the one that costs the least amount of money so you would get the Big Gulp which is 48oz for $1.39
Thursday: 2 choices {museum, park}
Friday: 4 choices {shopping, jet ski, hiking, and the choice not chosen for Thu}
Saturday: 1 choice {food}
Sunday: 3 choices {the remaining 3 after Friday's choice}
The total number of ways these choices can be arranged is 2×4×1×3 = 24
The apprpropriate selection is A) 24.
I dotn believe that a pair of angles can be vertical and supplementary. because vertical angles are across from each other, and supplementary angles are two angles next to each other (adjacent) that have a sum of 180. im not sure how to give an example/nonexample.
