10/100 x 2000 = 200
2000-200 = 1800
then it decreases by 20% so
20/100 x 1800 = 360
1800-360 = 1440
im not sure about this part
25% of 2000
25/100 x 2000 = 500
so 1440 + 500 = 1940
7x + 3 ≥ 52
7x ≥ 49
x ≥ 7
The only graph that works for this one is B, so we don't even need to check the other one.
Answer:
x = 38°
Step-by-step explanation:
An external angle is equal to the sum of the opposite internal angles of a triangle. Either of the internal angles at the base can be found as the supllement of its external angle.
∠OLM = 180° -134° = 46°
Then
... x +46° = 84°
... x = 38° . . . . . subtract 46°
A + 5 > -7....subtract 5 from both sides
a > -7 - 5
a > - 12
