Let x be the original cost for the sofa.
X x (1 + 0.07) =3210
X = 3000
Now we know the cost for the sofa.
Let p be the profit percent.
3000 x (1 + p) = 3360
P = 0.12
So the percentage profit is 12%
Answer:
Step-by-step explanation:
The two acute angles add up to 90 degrees. That's because every triangle has 180 degrees and a right angle is 90 degrees.
<m1 + <m2 + 90 = 180 Subtract 90 from both sides.
<m1 + <m2 + 90 - 90 = 180 - 90 Combine
<m1 + <m2 = 90
Let m1 = 9*m2 Substitute.
9m2 + m2 = 90 Combine
10 m2 = 90 Divide by 10
10m2/10 = 90/10
m2 = 9
m1 = 9*m2
m1 = 9 * 9
m1 = 81
The right angle = 90
m1 = 81
m2 = 9
Answer:
y = -x +3
Step-by-step explanation:
Think about the Y= mx + b
m = -1 so it's -x
b = 3, so it's +3
y intercept goes after the slope:
Y= Mx + B
Y = -x + 3
