Sum of angle in a triangle is 180, so 33+70+x=180
x=77
x and y are vertical angles so y=77
A ∩ B = {2, 4} [intersection (∩) means the common terms]
Answer:
9.6p + 0.4q + 2.2r meters (answer A)
Step-by-step explanation:
We sum up the three side lengths to obtain the perimeter of the triangle:
(6.2p + 4.5q) meters, , and (2.9r – 4.1q) meters
+ (3.4p – 0.7r) meters
+ (2.9r – 4.1q) meters
---------------------------------
9.6p + 0.4q + 2.2r meters (answer A)
Answer:
D
Step-by-step explanation:
When you flip a point around the y axis the x value is inverted since the point is moved to the opposite side across the y axis.
Let x equal the cost of one muffin and y equal the cost of quart of milk
8x+2y=18
3x+y=7.50
See if you can solve it from there. If not let me know
