Answer:
60+80+x=180
Step-by-step explanation:
__ + __ + __ = __ fill in the blanks
if 60, 80, and y have a sum of 180, the equation is 60+80+x=180
The third answer
1 quarter, 6 dimes, 1 nickel, 7 pennies
Answer:
y =
x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = - 3x + 13 is in this form
with m = - 3
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 
y =
x + c ← is the partial equation
To find c substitute (6, 10) into the partial equation
10 = 2 + c ⇒ c = 10 - 2 = 8
y =
x + 8 ← equation of line
X+y=8
multiply the first equation by 3 to get rid of x
3x+3y=24
3x+2y=14
subtract equation 1 from 2
y=10
substitute to find the value of x
x+10=8
x=-2
