Answer:
640 dm
Step-by-step explanation:
200+40+400=640dm
Since is addition you do the opposite and subtract 12 from 12 and -5 then 12 cancels out and -5-12=-17
Farrah's total score for both rounds will be -3.
Since the leader board shows Farrah's score as 5 on the front nine, this will be: +5
Since the leader board shows Farrah's score as 8 on the back nine, this will be -8. Then we'll add both together to get the total score which will be:
= 5 + (-8)
= 5 - 8
= -3
His total score will be -3.

Answer:
The value of x = 513
Step-by-step explanation:
Let x, y, and z be the three numbers
Given

Assuming x be the number which is 50% more than the sum of the other two numbers.
i.e.
(150)% of (y+z) = 1.5(y+z)
y + z = x/1.5
As we know that

substituting y + z = x / 1.5 in the equation

Multiply both sides by 1.5



Divide both sides by 2.5


Therefore, the value of x = 513
Answer:
y=2x-1
Step-by-step explanation:
straight line equation
y=mx + c
find gradient(m) first,use formula;
m=3-7/2-4
m= -4/-2
m=2
use one the coordinates
(2,3)
3=2(2)+c
3=4+c
c=3-4
c = -1
y = 2x - 1
