Answer:
PL 4
GL 12
HJ 10
Step-by-step explanation:
PL pythagoras theorem
-8x+2=-7x+10
-x+2=10
-x=8
x=-8
This is basically a system of 3 linear equations with variables x, y and c.
x+y = 6...................................(1)
5x/3 + y = c .........................(2)
2y = c-4x .............................(3)
(2)-(1)
5x/3-x +y-y = c-6 => 2x/3 = c-6 => x = (3/2)(c-6)=3c/2-9 ..............(4)
(3) - 2(2)
2y-2y - 10x/3 = c -4x -2c
=> 2x/3 = -c
=> x = -(3/2)c.............................................................................................(5)
Finally, equate (4) & (5) to get
3c/2-9 = -3c/2
=>
3c = 9
=> c=3
If she has finished 20%, she still has 80% to do. So just calculate .8 times 150.
Answer: just read
Step-by-step explanation:
So first you plot the points, then calculate how many units it takes from the point that is Sean’s house to his School. Show your work on that by drawing out your skip counting. Then you plot the rest of the points and fpro this calculation: the distance from Sean’s house to his school+ from his school to the grocery store. Then you calculate the distance (in units! ! ! Which means one box is one unit) : distance from Sean’s house to the school+ from school to the commmunity center. Then two calculations you made above you compare. So whichever one is greater is your answer for part b.
