Answer:
The first five terms would be 2,4,6,8,10,12
Step-by-step explanation:
2+2=4
4+2=6
6+2=8
8+2=10
10+2=12
x = number of questions
3y = points for a correct answer
-1x or -x = points for an incorrect answer
Adding up the correct and incorrect points/answers gives us the final score. We can solve to see how many questions were incorrect. (We are told 10 were correct)
3y + (-1x) = 20
3(10) + (-1x) = 20
30 - x = 20
10 = x
x = 10
So she got 10 correct and 10 incorrect, and there were 20 questions in all.
According to Newton's second law of motion, the force acting on an object is equal to the mass multiplied by the acceleration of the moving object. Since the object is moving in a constant velocity, acceleration is zero. Hence regardless of the mass of the car, the force acting is zero provided that air resistance and friction is negligible
I think The answer is b. 17
To find out how much Marie will save you have to multiply the 20% with the original praise which is $40.00. So we’ll change the 20% to 0.20 to multiply it with 40.
0.20 x 40 = 8
So Marie will save $8.00 using the coupon
