Answer:
x = 8
Step-by-step explanation:
For the triangles to be congruent, then the legs
ED = AB, that is
4x + 2 = 34 ( subtract 2 from both sides )
4x = 32 ( divide both sides by 4 )
x = 8
Answer:
y = - 
x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = 
= 
= -
Since the line crosses the y- axis at (0, 6) ⇒ b = 6
y = - x + 6 ← equation of line
Answer:
108
Step-by-step explanation:
Robin cleans 72 rooms in 6 days,
so he cleans 72 rooms / 6 days = 12 (rooms /day),
so 9 days he could clean (12 rooms / day) * (9 days) = 108 rooms
(total bill)*(percent of bill)=(money paid for that part of bill)
total bill=$132.00
electric %= 0.58 (1-.42)
gas %= 0.42
132*.42=55.44
132*.58=76.56
The Millers paid $55.44 for their gas bill. The Millers paid $76.56 for their electric.
**you can check this because $76.56+$55.44=$132
