Answer:
C. 19
Step-by-step explanation:
90+26=116
180-116=64
3x+7=64
3x=57
x=19
Answer:
C
Step-by-step explanation:
(6 * 4 ) * 2 = 48
( 4 * 12 ) * 2 = 96
( 6 * 12 ) * 2 = 144
48 + 96 + 144 = 288
Hey there!
To start, you have one of your angles given, 40.5. Now, given that the airplane is directly over point A of the triangle, you can conclude that ∠A is 90 degrees.
Knowing that the sum of all the angles of a triangle is 180 degrees, to find ∠P, you can set up this equation (where x is the missing angle of ∠P):
40.5+90+x=180
Simplify and solve for x:
40.5+90+x=180
130.5+x=180
x=49.5
Therefore, m∠P is equal to 49.5 degrees.
Hope this helps and have a marvelous day!
Answer:8 weeks
Step-by-step explanation:
So here is our equation for your question: 125 + 15x = 245
You then have to subtract 125 from both sides so we can isolate our variable which will give us 15x = 120 . Divide 15 from both sides : 15x/15 = 120/15 which will give us x = 8.
So it will take 8 weeks for her to buy a bike.
So y=9....
9=-3x+6
3=-3x
x=-1
so answer.....-1,9.....that is C
