Answer:
One solution
Step-by-step explanation:
First, organize the equations by moving y to the left hand side:
5x + 2y = 6, subtract 5x from both sides and we get: 2y=6-5x
3y = 2x + 9 is already done
Next, set the coeficcient of both y values equal to the least common multiple of 2 and 3 which is 6:
2y=6-5x multiply both sides by 3, 6y = 18-15x
3y=2x+9 multiply both sides by 2, 6y = 4x+18
Substitute y on both sides and we get 18-15x=4x+18
Simplify that and you get 19x=0, x equals 0, so there is one solution

Answer:
1.3 < 1 3/5
Step-by-step explanation:
You could convert the decimal to a fraction.
1.3 - 1 3/10
1 3/5 = 1 6/10
Another method would be to convert the fraction to a decimal.
3/5 = 6/10 so 1 3/5 = 1.6
1.3 < 1.6
<span>The ramp's horizontal distance is the distance in the x-axis. So the ramp's vertical distance I.e y-axis is 14 inches. And its length which is actually the hypotenuse ofthe right angled triangle 16 feet. But let's convert feet to inches first.
1 feet makes 12 inches
Hence 16 feet makes 192 inches.
From pythagoras
a^2 =b^2 + c^2 where a the hypotenuse is 192 and b is 14. C is the ramp's horizontal distance.
So we have (192)^2 = (14)^2 + c^2
C^2 = 192^2 - 14^2 = 36668
C = 191.48
From SOHCAHTOA. We have to use Sin
So sin theta = (14/192)
Theta = sin^(-1) (14/192) = 4.1815.
Yes, it meets the FAC standard since the ramp's angle is less than 4.78</span>
