Answer: There are 4 tubes of paint she purchased.
Step-by-step explanation:
Since we have given that
Amount spend on tubes of paint and brushes for an art project = $16
Cost of each tube of paint = $3
Cost of each brush = $0.50
Let the price of tube of paint be 'x'.
Let the price of brush be '2x'.
So, According to question, it becomes,
Hence, there are 4 tubes of paint she purchased.
I have a strong felling the answer is the fourth shoice according to my calculations.
Answer:
y=2x+10
Step-by-step explanation:
In line equations its helpful to write your line in the form y = ax + b. This helps because a is always the gadient of the line and b is always the y intercept.
In this case it is y=2x+3
All parallel lines have the same gradient. The gradient of this line = 2.
If the line crosses the x axis at x=-5, then when x =-5 y = 0.
If you put all this in the form y =ax + b you get 0 = 2(-5) +b
So all you need to do to find b is rearrange. b = 10.
Therefore your line has gradient 2 and y intercept 10.
y = 2x + 10
The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.
