You need to convert lbs into ounces, so do 5×16, to get 80ounces and after doing jt, it woukd appear that 80 ounces and 5 lbs are equal to each other
Answer:
25 degrees
Step-by-step explanation:
The sum of the 80 and 55 degree angles and the unknown angle x must be 180 degrees. Thus, x + 80 + 55 = 180, or x + 155 = 180, or x = 25.
x is 25 degrees.
This is based upon the "corresponding angles" principle. Lines AB and CD are parallel and are intersected by the longer diagonal line if we extend this line past the 80 and 55 degree angles.
<span>-x + 5y= -18 so x = 5y + 18
5x-9y=10
substitute </span>x = 5y + 18 into 5x - 9y = 10
5x - 9y = 10
5(5y + 18) - 9y = 10
25y + 90 - 9y = 10
16y = - 80
y = -5
x = 5y + 18
x = 5(-5) + 18
x = -25 + 18
x = -7
answer
(-7, -5)
