Answer:
x = 37
Step-by-step explanation:
3y - 20 + x + 13 = 3x + 9
3y - 16 = 2x
1.5y - 8 = x
2y + 3x + 9 = 180
2y + 3x = 171
2y + 3(1.5y - 8) = 171
2y + 4.5y - 24 = 171
6.5y = 195
y = 30
1.5y - 8 = x
1.5 * 30 - 8 = x
45 - 8 = x
37 = x
0.40x + 55 = 0.15x + 80
0.40x - 0.15x = 80 - 55
0.25x = 25
x = 25 / 0.25
x = 100 minutes <=
To find the length of the yellow segment, we have to use Pythagorean's Theorem. But first, we have to find the length of the black line at the bottom.
Where a = 4ft and b = 9ft.
So, the length of the black segment is 9.8 feet.
Now, we find the yellow line length
Where a = 4 and b = 6.
<h2>Therefore, the length of the yellow line is 7.2 feet.</h2>
Answer:
x = 1/2 or 3
Step-by-step explanation:
Compare the given equation to the standard form equation to identify the values of the variables in the formula. Then put those values in the formula and do the arithmetic.
