(a) Coordinates:
A (0, 0)
B (3, 2)
C (9, 6)
Triangle A to B has a change of +3 in x values, but Triangle B to C has a change of +6 values so each triangle doesn’t have the same changes in x values.
Triangle A to B has a change of +2 in y values, Triangle B to C has a change of +4 values so each triangle doesn’t have same change in values.
Triangle A to B change in y over change in x = 2/3, Triangle B to C change in y over change in x = 4/6, both have decimal values of 0.66. Therefore, each triangles has the same ratio of change in y over change in x.
Answer:
80% of 20 is 16.
Step-by-step explanation:
Answer: Width=2.86 in.
Explanation: Since we have a proportion, we can use the equation 1.8/4.4=1.17/x.
Cross multiplying gives us 1.17*4.4=1.8x and solving for x gives us 2.86 in.
Answer:
16
Step-by-step explanation:
Parentheses first then multiplication and then add those two
Answer:
8.) -120
9.) -5
10.) -1
Step-by-step explanation:
8.) ab - c
5(-12) - 60
-60 - 60 = -120
9.) -10 - (-7) + 2 (3 - 4)
-3 + 2(-1)
-3 + (-2) = -5
10.) Add all the numbers up then divide by how many numbers there are.
