Answer:
9 hours
Step-by-step explanation:
If she makes $ 20 for each car, washing 9 cars in 3 hours would get $ 180.
So she will need to work 9 hours 180 + 180 + 180, washing 9 cars in 3 hours and would get $ 540. This is enough to buy her phone and she will have a surplus of $ 120.
In summary she must work 9 hours

Answer with explanation:
We have to graph the Linear equation:
→ y-4 =x+2
⇒To draw a line you need two points that lies on the line.
→Point (-2,4) lies on the line,as
L HS→4-4=0
R HS → -2 +2=0
→From Point (-2,4) finding a point which is left 1 unit and down 3 units is equal to = (-2-1 ,4-3)
= (-3,1)
→And from Point (-2,4) finding a point which is left 3 unit and down 1 unit is equal to = (-2-3 ,4-1)
= (-5,3)
→None of the two points that is (-3,1) and (-5,3) lie on the linear function
which is, y-4 =x+2.
≡None of the option

Answer:
9 3/5
Step-by-step explanation:
When we see a percentage, we know that the base is 100. In other words, 960% is equal to 960/100
With this, its just a matter of transforming the improper fraction to a mixed number.
100 fits 9 times in 960 so there will be 9 wholes
the remaining 60/100 can be simplified to 3/5 through this process:
60/100 = 6/10 = 3/5
Answer:
2bc
Step-by-step explanation:
The product of c and b means c X b. However, in algebra, we typically miss out the X (multiply) symbol. We also like to put letters in alphabetical order. So this means the product of c and b is written as bc.
Then, to double a number, this just means to multiply by 2.
so we have 2Xbc. But, again, we don't write in the multiply symbol. We also put numbers in front of letters.
So this becomes 2bc.
