Answer: -2a + 3b
Solution:
3b - 2a
Simplify
= -2a + 3b
The value is
or
, since it is in the tenths place.
3 plus 1 equals 4 so its 4/6. When you simplify it the answer is 2/3
Given problem is -4.2y+2.1>-2.52.
To solve this, we combine numbers by transposing -2.52 to the left side and transposing variable term in the right side as shown below:
2.1+2.52>4.2y
Perform addition of values 2.1 and 2.52,
4.62>4.2y
Then, divide both sides with 4.2 and the result is 1.1>y.
The answer is y<1.1.
Answer:
$1.5 and $8.75
Step-by-step explanation:
Given data
let tables be x and chairs be y
The total cost to rent 3 chairs and 2 tables is $22
so
3x+2y=22----------1
The total cost to rent 5 chairs and 6 tables is $60
so
5x+6y=60---------2
the system of equation is
3x+2y=22----------1X 6
5x+6y=60---------2X 2
18x+12y= 132
- 10x+12y=120
8x+0y= 12
8x= 12
divide both sides by 8
x= 12/8
x=$1.5
put x= 1.5 in 2
5(1.5)+6y=60---------2
7.5+6y=60
6y=60-7.5
6y=52.5
divide both sides by 6
y= 52.5/6
y=$8.75
