A: x<-18
B: x>-30
C: x>-18
D: x<-30
Answer:
answer is A: x<-18
Step-by-step explanation:
3-x/2>12
multiply both sides by 2
6-x>24
move constant to right
-x>24-6
subtract numbers
-x>18
change the signs
x<-18
35 tiles
B)
70 tiles
C)
100 tiles
D)
300 tiles
Number of tiles required is 300 tiles
Given that;
Dimensions of room = 15 ft × 20 ft
Area of tiles = 1 ft. square
Find:
Number of tiles required
Computation:
Area of room = 15 × 20
Area of room = 300 ft, square

Answer:
D) 300 tiles
Step-by-step explanation:
20 * 15 = 300
Answer:
see explanation
Step-by-step explanation:
Using the Addition/ Subtraction formulae for cosine
Consider the left side
cos(x - y) - cos(x + y)
= cosxcosy + sinxsiny - (cosxcosy - sinxsiny) ← distribute
= cosxcosy + sinxsiny - cosxcosy + sinxsiny ← collect like terms
= 2sinxsiny = right side ⇒ proven
Answer:
Proceed the next step, then. Whether it is sum/subtract the addends, whether it is subtract. Then isolate the variable, aiming to find out the quantity of x.
Step-by-step explanation:
If an equation whose product does not need the distributive property, then the factors have already been distributed. And
Visualizing it
Suppose the following equation:
Now let's focus the following step, that point of the question, when the equation does not need the distibutive property:
3x +6=4
3x+6 -6=4-6
3x=-2
3x/3=-2/3
x=-2/3
S={-2/3}
