Answer:
x=11, y=2
Step-by-step explanation:
We can set 1 equal to x-5y and then solve for x. and y.
x = 5y+1
y = x-1/5
We can use this information and plug back in the values for 3y-x or x-5y.
We can set -3 = 3y-x or 1 = x-5y.
To solve for x using -3 = 3y-x we can swap the values of x and y which would make it -3 = 3(x-1/5)-5(x-1/5)+1.
We can do a bit of algebra which would get us x = 11.
Knowing that y = x-1/5 we can plug in 11 for x. y = 11-1/5.
y=2
x=11, y=2
By minusing 12 to both sides
d+12=2
-12=-12
d =-10

Answer:
1/4
Step-by-step explanation:
We can use the slope formula to find the slope
m = (y2-y1)/(x2-x1)
= (2-0)/(4 - -4)
= (2-0)/( 4+4)
= ( 2/8)
= 1/4
Answer:
question 67-the answer is Rory has eaten 1 1/4 of all the chocolate he has been given.
question 68-answer A-30 degrees
Step-by-step explanation:
question 67:
first Rory ate 1/2 of his chocolate
then, his sister gave him another whole chocolate bar an hour later.
that is 1/2+1=1 1/2--3/2/2=3/4
add 3/4 and 1/2--3/4 1/2~2/4--2/4+3/4=5/4 or 1 1/4
so the answer is 1 1/4
question 68:
if you draw a base to connect the last side of the angle into a triangle, you find that all three sides are equal, making the triangle an equilateral triangle. An equilateral triangle's angles all equal 30 degrees.
so, the answer is answer A: 30 degrees
