Answer:
The length of AA' = √29 = 5.39
Step-by-step explanation:
* Lets revise how to find the length of a line joining between
any two points in the coordinates system
- If point A is (x1 , y1) and point B is (x2 , y2)
- The length of AB segment √[(x2 - x1)² + (y2 - y1)²]
* Lets use this rule to solve the problem
∵ Point A is (0 , 0)
∵ Point A' = (5 , 2)
∵ (x2 - x1)² = (5 - 0)² = 5² = 25
∵ (y2 - y1)² = (2 - 0)² = 2² = 4
∴ The length of AA' = √(25 + 4) = √29 = 5.39
U can find the unit rate by looking where is the point so in that pic the unit rate I see is: 3/5
Answer: The answer would be x < 10/7
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
7*x (10)>0
Step by step solution :
STEP
1
:
Pulling out like terms
1.1 Pull out like factors :
7x - 10 = -1 • (7x + 10)
Equation at the end of step
1
:
STEP 2
:
2.1 Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number
7x+10 < 0
2.2 Divide both sides by 7
x+(10/7) < 0
Solve Basic Inequality :
2.3 Subtract 10/7 from both sides
x < 10/7
Inequality Plot :
2.4 Inequality plot for
7.000 x - 10.000 > 0
One solution was found :
x < 10/7
The first step is to find out the value of one diaper for each equation
39.98/216 = 0.18
Therefore one diaper is for 0.18 cents
24.99/88 = 0.28
Therefore one diaper is for 0.28 cents
At the end the first deal is better
