Step-by-step explanation:
because it is a straight line locate at x = 6 that pass to every y coordinate, so it pass -8 too.
To start off, you have to change 2/3 into 3/2 and then multiply it by 3/4. (Which the equation becomes into 3/4 × 3/2.) Then solve 3/4 × 3/2 =9/8 or 1 and 1/8.
Answer:
71˚
Explanation:
To find the <em>mean</em> of a sum of numbers, you add all the numbers together, and then divide by how many numbers there are.
71 + 72 + 68 + 67 + 74 + 72 + 73 = 497
497 ÷ 7 = 71
