The answer is: cosV=39/89=0,43
Answer:
y = x -2
Step-by-step explanation:
Equation of the line : y =mx + b
m = 1
y = 1x + b
Plugin x = 4 and y =2 in this equation
2 = 1*4 + b
2 -4 = b
b = -2
Equation: y = x - 2
Let the perimeter be x.
3x = 75 - 2x
Add 2x from both sides:
5x = 75
Divide both sides by 5:
x = 15
Answer: The perimeter is 15 units.
Answer:
To thirds if I'm not wrong
Step-by-step explanation:
three fourths meaning 3/4 of a number is 1/2
so:
3/4 of number is 1/2
1/4 of number = number ÷ 4
3/4 of number = (number ÷ 4) × 3
(number ÷ 4) × 3 = 1/2
<divide both sides by 3>
number ÷ 4 = 1/6
<multiply both sides by 4>
number = 4/6
<show in lowest term>
number = 2/3
the number is 2/3
Theos number is -2/5
4x + 20 = 10
-20 -20
4x = -10
x = -4/10
x = -2/5
