X+127 = 180
x = 180 - 127
x =53
y + 74 = 180
y = 180 -74
y = 106
answer B.
x = 53, y = 106
Answer:
perimeter = 20 m
Step-by-step explanation:
given the area of the square = 25 m² and
area of a square = s² ( where s is the side length ), then
s² = 25 ( take the square root of both sides )
s = = 5 ← length of side
perimeter = 4s = 4 × 5 = 20 m
Unit price is total price/ quantity purchased.
21.16 / 4 = 5.29
Unit price = $5.29 per pair
ANSWER :
A 180 degrees rotation about the origin.
EXPLANATION.
Let us name the vertices of the triangle as follows.
If we reflect the triangle across the y-axis, then we have to negate the x-coordinates
to get,
If we now reflect triangle ∆A'B'C' in the x-axis, we will have to negate the y-values to obtain,
The single transformation that will map ∆ABC to ∆A''B''C'' is
This is a rotation of 180 degrees about the origin.
Answer:
3x
Step-by-step explanation:
2y + 1 + x + ? = 2y + 1 + 4x
Subtract 2y from each side
2y -2y+ 1 + x + ? = 2y-2y + 1 + 4x
1 + x + ? = 1 + 4x
Subtract 1 from each side
1 -1+ x + ? = 1 -1+ 4x
x + ? = 4x
Subtract x from each side
x-x+? = 4x-x
? = 3x
