Answer:
The player answer correctly 30 questions
Step-by-step explanation:
First we have to develop the information that gives us as 2 equations
x = correct answer
y = incorrect answer
z = score = 40
h = total answer = 50
2x - y = z x + y = h
2x - y = 40 x + y = 50
we clear the x of one equation and replace the value of x in the other equation
x = 50 - y
2x - y = 40
2(50 - y) - y = 40
100 - 2y - y = 40
-3y = 40 -100
y = -60/-3
y = 20
x = 50 - y
x = 50 - 20
x = 30
Answer:
1 7/12 cups
Step-by-step explanation:
3/4 + 5/6
LCM of 4 and 6 is 12 so we have
9/12 + 10/12
=19 / 12
= 1 7/12 cups of milk
1) add 8x on both sides
3y=12+8x
2)divide by 3 to solve for y
y=4+8/3x
y=8/3x+4
8/3x is the slope, 4 is the y-intercept
Answer:
Frank was going around his school and was asking fellow students how many scoops of ice cream they like for desert. He learned that zero students like 3 scoops of ice cream. The more students he asked the smaller the amounts got. The amounts got smaller by half a scoop per person. When he asked a 6th person they did not want any ice cream scoops for desert.
Step-by-step explanation:
Y intercept: 3
Slope: - 1/2
