Answer:
Step-by-step explanation:
Total interior angles in a triangle=180 degrees
That is: 3x + 10 + 5x - 1 + x =180
9x+9=180
9x=180-9
9x=171
x=171/9
x=19
Therefore
Angle A =67 degrees
Angle B= 94 degrees
Angle C = 19 degrees
Answer:
(9,3)
Step-by-step explanation:
4(.25x + .5y = 3.75) → x + 2y = 15
(4x – 8y = 12) → x – 2y = 3
2x = 18
Divide both sides by 2
x = 9
Substitute x = 9 into x + 2y = 15
9 + 2y = 15
Subtract 9 from both sides
2y = 6
Divide both sides by 2
y = 3
Solution
(9, 3)
Answer: m= 3
Step-by-step explanation:
Because 4xm=12 4x3=12 so the answer will be 3

Answer:
slope = -1/2 and y-intercept = 80
Step-by-step explanation:
A water tank has 80 gallons of water. But the tank has a leak from which water flows at a rate of 1 gallon every 2 minutes
Rate of change is the slope
Given that rate of change is 1 gallon every 2 minutes that is 1/2. The water flows out at the rate of 1/2. since it flows out the slope is negative.
So slope = -1/2
y intercept is the initial amount of water in the tank
A water tank has 80 gallons of water. so y intercept is 80 gallons of water
y intercept = 80
