Answer:
B) 77
Step-by-step explanation:
The sum of both values is 202. given that the total angle can only be 180 that would have to leave x with the value of -11 to equal 180 leaving the answer to be B 77.
Answer:
Step-by-step explanation:
5x = 3x+18
2x = 18
x = 9°
2y = 10
y = 5
Answer:
500000 people
Step-by-step explanation:
The population grew by 600,000 which is 120% the earlier prediction by the town council.
Using direct proportion
600,000 -------- 120%
X --------- 100%
X = (600000 × 100) ÷ 120 = 500000
Therefore the earlier prediction by the town council is 500000 people
The slope perpendicular to the one given is the opposite reciprocal. So the slope of the "new" line will be -1/5. Using y = mx + b and filling in 3 for y, -10 for x and the slope, m, of -1/5 will help you solve for b. Then use that b to write the new equation. 3= -1/5(-10) + b and b = 1. Your equation, then, is y = -1/5x + 1
