Yes it is zero because it has no number just a variable with a percentage sign
x+y = -19
x*y = 35
x=-19-y
(-19-y)y = 35
y^2 +19y +35 = 0
y = -2.066965626
therefore x=35/y = -16.93303437
Answer:
15
Step-by-step explanation:
y=mx+b
b is the intercept
in this equation "m", the slope, would be one. the y-intercept, or "b" would be 15
The computation shows that the value of blue which is represented by x is 12.
<h3>How to calculate the value?</h3>
From the information given, it was stated that 30 people were in the kindergarten.
Green = 10
Red = 8
Blue (x) = 30 - (10 + 8)
= 30 - 18
= 12
Since the teacher want to paint the class with the most favorite color, the appropriate color to use will be blue.

Answer: x = 10°
(2x + 50) = 70°
(3x - 10) = 20°
Steps:
(2x + 50)° + (3x -10)° = 90°
2x + 50 + 3x - 10 = 90°
5x + 40 = 90°
5x = 50°
x = 10°
(2x + 50)
2(10) + 50
20 + 50
70
(3x - 10)
3(10) - 10
30 - 10
20
Check:
70 + 20 = 90
90 = 90 ✅
