Answer: 8+18W
Step-by-step explanation:
1. First multiply the 4 by 2, equalling 8.
2. Then multiply the 9W by 2, equalling 18W.
3. 8 and 18W are unlike terms, so they can not be added together.
4. The answer would stay as 8+18W.
Let books =x and games =y
2x+2y=26
4x+1y=28
If you solve for x and y, x=5 and y=8
Answer:
9514 1404 393
Answer:
C The unit rates are the same.
Step-by-step explanation:
The rate of change for the equation is the coefficient of x: 4.5.
The rate of change for the table is computed as described in the problem statement:
unit rate of change = ∆y/∆x = (18-9)/(4 -2) = 9/2 = 4.5
The unit rates are the same.
Step-by-step explanation:
Answer:
108
Step-by-step explanation:
You start by finding the area of the trapezoid, which is ((3+5)/2) 3 = 12, then you multiply 12 by 9 which is 12*9 = 108
Answer: The equation has one solution
Step-by-step explanation: First , open the brackets
7( 12 - 2x ) = 4 (3 - 3x )
84 - 14x = 12 - 12x
collect the like terms
84 - 12 = - 12x + 14x
72 = 2x
Therefore divide through by 2
x = 72/2
x = 36
Therefore, the equation has only one solution
