Answer:
D 138
Step-by-step explanation:
the outside angle(x) of a triangle whose base is extended is always equivalent to the farthest 2 inside angles of the triangle.
x = 48 + 90 = 138
Answer:
I believe the answer is A. 130
Answer:
<u>After a 75% increase, it would become</u>
x + 75%x = x + 0.75x = x(1 + 0.75) = 1.75x
<u>After a 50% decrease, it would become</u>
1.75x - 50%(1.75x) = 1.75x - 0.5(1.75x) = 1.75x - 0.875x = 0.875x = 
Because
is less than x, the new amount would be less than the original.
I feel like it’s either 1 or 2
First, turn the fractions into mixed numbers.
21/4 - 27/8
Then. make the denominators the same.
4 * 2 = 8
21 * 2 = 42
42/8 - 27/8
42 - 27 = 15
15/8
15/8 = 1 7/8
