Answer:
a. 14
b. 1
c. 2
Step-by-step explanation:
If there are 4 one point questions and 5 two point questions, then 5 multiplied by two is 10 and adding it to 4 is 14. The quiz would be 14 points total. If you scored 87.5% on the quiz then you would know that you got 12 of the questions correct and you would know that by finding 87.5% of 14 which the equation to do so would be 87.5/100= 0.875, then 0.875* 14= 12.25. If you round 12.25 to the nearest whole number then it's 12. And since you got all the 1 point questions right, then you must of gotten 1 two point question wrong.
I hope this helps!
The x-coordinate of the midpoint is the average of the x-coordinates of the endpoints. The y-coordinate of the midpoint is the average of the y-coordinates of the endpoints.
x-coordinate of midpoint: (-4 + 0)/2 = -4/2 = -2
y-coordinate of midpoint: (9 + 7)/2 = 16/2 = 8
Answer: The midpoint is (-2, 8).
that is true if that's 1/3n=7/12
if it's 1/3n-7/12 then the first step is to equal it to zero
Answer:
The answer is seven
Step-by-step explanation:
To solve
if you have |a|=b, solve a=b and a=-b
|4x+12|=16
solve
4x+12=16 and 4x+12=-16
minus 12 both sides
4x=4 and 4x=-28
divide both sides by 4
x=1 and x=-7
