Answer:
Step-by-step explanation
larger angle = 76+2x
smaller angle = x
supplementary angles add up to 180
∴(76+2x)+x=180
76+3x=180
3x= 180-76
3x = 104
x = 104/3
x = 34.7°(smaller angle)≈ 35
larger angle = 76+2(34.7)
=76+69.4
=145.4≈ 145
Answer:
answer is A.
Step-by-step explanation:
divide price by amount of kg to see how much it cost per kg. Find the lowest answer by doing this to all answers. Don't forget to round to the nearest cent!
For this case we must solve the following expression:
![-11 (-7)](https://tex.z-dn.net/?f=-11%20%28-7%29)
By law of multiplication of signs we have to:
![- * - =+\\- * + = -\\+ * - = -\\+ * + =+](https://tex.z-dn.net/?f=-%20%2A%20-%20%3D%2B%5C%5C-%20%2A%20%2B%20%3D%20-%5C%5C%2B%20%2A%20-%20%3D%20-%5C%5C%2B%20%2A%20%2B%20%3D%2B)
Also we must find the product of 11 and 7, this is equivalent to:
![11+ 11+ 11+ 11 +11+ 11 + 11 = 77](https://tex.z-dn.net/?f=11%2B%2011%2B%2011%2B%2011%20%2B11%2B%2011%20%2B%2011%20%3D%2077)
Thus, the result of the expression is +77.
Answer:
![-11 (-7) = 77](https://tex.z-dn.net/?f=-11%20%28-7%29%20%3D%2077)
