Answer:
18-4y=62, u can solve it if u want and u can also subsitute any variable or a constant
Answer:
x = 36 and y = 72
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
y is an external angle to the triangle on the right, thus
y = 2x
The sum of the 3 angles in a triangle = 180
Consider the triangle on the left. then
x + 2y = 180 ← substitute y = 2x
x + 4x = 180
5x = 180 ( divide both sides by 5 )
x = 36 and y = 2x = 2 × 36 = 72
If for every 2 to that get in 1 has to go out. keep the 2:1 ratio and make it equal 28:e. use cross multiplication to get that e=14
Hello! Just by looking at the answer choices, the second and third choices are eliminated, because while you do get a 30% discount, you still have to pay 70% of the remaining price. You don't know the discounted price, so the first choice is also out. The best answer is the last one, because you find the discount price by multiplying 70% (0.7) by 2.40. The fourth choice is the correct answer.
