Answer: 4/15
Step-by-step explanation:
Make the denominators equal first including the numerators. So, the common factor is 15. So 2/3 turns into 10/15 and 2/5 turns into 6/15. Now subtract. 10/15-6/15 is 4/15
Answer:
(-3x+30)
Step-by-step explanation:
We first distribute: 4(x+7) = 4x+28
Then, we bring it down.
4x+28-7x=2
Combine like terms.
4x+(-7x) = -3x ... 28+2 = 30.
Combine both results.
-3x+30
Ok so after a loss of 28% she sold for 160
100-28=72
therefor
160=72%
find 100%
160:72=x:100
160/72=x/100
20/9=x/100
mutlply both sides by 900
2000=9x
divide boht sides by 9
222.2222222222=x
about $222.22
Answer:
Request equation :
y-17x=128
Step-by-step explanation:
As we know that if (x1,y1) & (x2,y2) be two points then it's point slope form equation can be written as
y-y1 = (y2-y1)/(x2-x1) {x-x1}
now we have (-8,-8) and (-7,9) then the equation will become
y-(-8)=(9-(-8))/(-7-(-8)) {x-(-8)}
i.e, y+8=17(x+8)
i.e, y -17x =128
