Answer:
The answer is 3
Step-by-step explanation:
25% of 2.40 equals 0.6
so 3 will be the total price and he will get 0.6 profit.
Answer:The scale factor is (√10) / (4)
Explanation:The complete question as well as the rule for the distance between two points are shown in the attached image.
To get the scale factor, we will follow these steps:1- Length of AB:AB = √(5-9)²+(-4-4)²
AB = √80
AB = 4√5 units
2- Length of A'B':A'B' = √(5-6)²+(-4-3)²
A'B' = √50
A'B' = 5√2
3- getting the scale factor:A'B' = k AB where k is the scale factor
5√2 = k * 4√5
k = (√10) / (4)
Hope this helps :)
Answer: y = 2 x = -2
Step-by-step explanation:
-x + y = 4
x + 3y = 4
Since x and -x are opposite, we can use the system of elimination
To do that, we add the first equation and the second equation together
-x + y = 4
+
x + 3y = 4
↓
4y = 8
Now we solve for y
4y = 8
Divide both sides by 4
y = 2
Since we now know y, we can solve for x by substituting y for 2 in one of the equations.
x + 3y = 4
Substitute y for 2
x + 3 (2) = 4
x + 6 = 4
Subtract 6 from both sides
x = -2
