Answer:
0.4
Step-by-step explanation:
15 = 5p - 13
-13 = 5p -13
---------------- ( subtract 13 on both sides )
<u> 2 = 5p</u>
5 = 5p
---------------- ( divide 2 by 5 )
p = 0.4
( p equals 0.4 )
Answer:
11 ft =132in
Step-by-step explanation:
first u multiply the length value which is 12
11 x 12 = 132
We have three similar triangles, let's see if we can get this right, right vertex first, then other vertex from small side:
EDF ~ GDE ~ GEF
As ratios that means
ED:DF:EF = GD:DE:GE = GE:EF:GF
x:20:y = 5:x:GE = GE:y:15
Since we're after y we choose
20/y = y/15
20(15) = y²
y² = 300
y = 10√3
y ≈ 17.32
Answer:
Your teacher is correct.
Step-by-step explanation:
Common knowledge about coordinates:
The first number in a coordinate is the "x coordinate".
The second number is the "Y coordinate".
The X axis is the horizontal line.
The Y axis is the vertical line.
The origin is the middle of the two axis's.
For A, the x coordinate is -4. You go right on the horizontal line because it is a negative number. The y coordinate is 4, so you go up from -4 to 4 because it is a positive number. there, you'll get your coordinate (-4 , 4).
For B, because the x coordinate is 0, you don't move at all, and you stay on the x origin. The y coordinate is 6, so you go up from the origin to 6. There, you'll have (0, 6).
C is pretty self explanatory if you understand the concept.
X should equal 8 because if you add the three numbers they give you. You will get 20 and the whole thing is 28
