Step-by-step explanation:
1.
(a) n ≤ 21
(b) n ≥ 5
(c) n > 3/5
2.
(d) n < 14
(e) n ≥ 14
Answer:
True
Step-by-step explanation:
True because if AC = BC, then the triangles are the same.
The equation would be .05x+50=100 Then you would solve for x
Answer:
DCB = 84
Step-by-step explanation:
Here, we want to calculate the value of the angle
To do this, we use an important parallelogram angle property
The adjacent sides are supplementary, meaning they add up to 180
We have this as;
180-96 = 84 degrees
Answer:
Solve by adding or subtracting like terms. (Ex. 2k + 4k = 6k; 9 + 7 = 16)
- 6k + 7k = 1k = k
(7 - 6 = 1)
12r - 8 - 12 = 12r - 20
(8 + 12 = 20 but sign is negative) 12r will stay the same because there are no terms with a letter r.
n - 10 + 9n - 3 = 9n + n - 10 - 3 = 10n - 10 - 3 = 10n - 13
(n = 1 so 9 + 1 = 10; 10 + 3 = 13 but negative sign)
- 4x - 10x = 14x
(10 + 4 = 14)
- r - 10r = 11r
(r = 1 so 10 + 1 = 11)
