Answer:
7 monkeys and 13 rabbits
Step-by-step explanation:
Let's define x as the number of monkeys that I sold. Then, I sold (x + 6) rabbits.
As I get $6 for each, I need to add the number of monkeys and rabbits I sold and multiply it by 6. That calculation has to be equal to $120 because that's my earnings.
Therefore, the equation we need to resolve is
(x + x + 6)*6 = 120
Let's divide by 6 on each side and add the x's:
(2x + 6)*6/6 = 120/6
2x + 6 = 20
Now we subtract 6 on both sides:
2x + 6 - 6 = 20 - 6
2x = 14
Now we divide by 2:
2x/2 = 14/2
x = 7
Therefore, I sold 7 monkeys and 7 + 6 = 13 rabbits.
Answer:
<T = 81
x = 10, angle = 60
Angle 5 and Angle 3 are vertical angles. They are acute angles
Step-by-step explanation:
Supplementary angles add to 180
(7x+11) + (8x+19) = 180
Combine like terms
15x + 30 = 180
Subtract 30 from each side
15x +30-30 = 180-30
15x= 150
Divide by 15
15x/15 = 150/15
x = 10
We want angle T
T = 7x+11 = 7(10)+11 = 70+11 = 81
The two angles add to 90
5x+10 + 30 = 90
Combine like terms
5x+40 = 90
5x+40-40 = 90-40
5x = 50
Divide by 5
5x/5 = 50/5
x=10
5x+10 = 5(10) +10 = 50+10 = 60
Angle 5 and Angle 3 are vertical angles. They are acute angles
Answer:
Equation in slope-intercept form that goes through (12, 4) and (20,8) is:
Step-by-step explanation:
Given two points are:
Slope intercept form of line is given as:
Here m is the slope of the line and b is the y-intercept.
Slope of a line is calculated by the formula:
Putting the values
Putting the value of slope in slope-intercept form we get
To find the value of b, any one point will be put in the equation
Putting the first point (12,4) in the equation
Putting the value of b
Hence,
Equation in slope-intercept form that goes through (12, 4) and (20,8) is:
