Answer:
1. x= -1/3
2. y= -4, x= 2
3. y=-2, x=1
Step-by-step explanation:
Answer:
2.4x +2.2
Step-by-step explanation:
5.4x−1.1−3(x−1.1)
The first step is to distribute the -3
5.4x−1.1−3(x) -3(−1.1)
5.4x -1.1 -3x +3.3
Now we need to combine like terms
5.4x-3x -1.1+3.3
2.4x +2.2
Answer:
x = 14
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + x² = (14
)²
2x² = 392 ( divide both sides by 2 )
x² = 196 ( take the square root of both sides )
x = 
= 14
Thus the congruent legs are 14 cm
Answer:
27
Step-by-step explanation:
Given that :
Dimension of poster board = 1 yd by 1 yd
Dimension of each poster sign = 1/3 yd by 1/9 yd
Number of poster signs that can be cut :
Area of poster sign = 1/3 * 1/9 = 1/27 yard²
Area of poster board = 1 yard²
Number of poster signs that can be cut :
Area of poster board / area of poster sign
1 yard² ÷ (1/27) yard²
1 ÷ 1/27
1 * 27/1
= 27 poster signs
