Answer:
The tip should be $9.00
Step-by-step explanation:
Answer:
x = 35
y = 7
Step-by-step explanation:
See how the image looks like two overlapping triangles. It is given that the triangles are congruent. Its easier to see whats what if you draw the triangles separately. I also flipped over the triangle on the right so they match. Record the given angle measures. Since A is 45° then D is also 45°. DBC is 30°, so we can find the missing angle in triangle DBC. Angles in a triangle add up to 180° so
C + 45 + 30 = 180
C + 75 = 180
C = 105°
This is angle DCB.
Now all the angles are marked. We can set up equations to find x and y. see image.
Answer:
10.5
Step-by-step explanation:
-10p+9=12
-9 -9
-10p=3
—— —
-10 -10
P=3/-10 or -0.3
Answer:
6
Step-by-step explanation:
I think you mean 2x=12. Divide 2 on both sides to get x=6
