Answer:
A variable is a quantity that may change within the context of a mathematical problem or experiment. ... The letters x, y, and z are common generic symbols used for variables. Sometimes, we will choose a letter that reminds us of the quantity it represents, such as t for time, v for voltage, or b for bacteria.

Total would be $67.2! Each shirt would cost $16.8 with tax!
First you'll take 18/2 which equals 9. Then 30/2 which equals 15. Then you can divide both 9 and 15 by 3. So 9/3 equals 3 and 15/3 equals 5. So the answer is 3:5.
The value of x=9° and ∠B=40°
Step-by-step explanation:
From angles relationship, ∠A =∠B=corresponding angles
5x-5°=3x+13°
5x-3x=13°+5°
2x=18°
x=18/2 =9°
∠B=3x+13°= 3×9°+13° = 27° +13° =40°

Answer:
B. (-2, 0) and (1, 0)
Step-by-step explanation:
The equation can be factored as ...
y = 2(x^2 +x -2) = 2(x +2)(x -1)
The x-intercepts are the values of x where y=0, so will be the values of x that make one or the other of the binomial factors zero:
x = -2
x = 1
Then the intercept points are (-2, 0) and (1, 0). . . . . . . . . matches choice B
