Answer:
Step-by-step explanation:
y = 50x - 165
It should be 12×18. 1:3 means you take where it's at, at 1 and multiply it's size by 3.
Answer:
Step-by-step explanation:
3x + x + 60 = 180.
first, we add the x's together.
4x + 60 = 180
then we see if they all have a common multiple. in this case, they do. they are all divisible by 4, so we can use that.
x + 15 = 45
then, just subtract 15 from both sides, that way we get the variable by itself.
x = 30
also, it is a right triangle. the top angle (3x) multiplied by 3 is 90. any triangle that has a 90 degree angle is automatically a right triangle.
My prediction would be 1,659 defective brakes. I hope this helps you
It would be 60cm because 40 plus 20 equals 60
