Answer: Distance from Belmont to Carson is 2\dfrac{1}{3}\ miles

Step-by-step explanation:

Since we have given that

Distance from Atherton to Carson = 13 miles

Distance from Atherton to Belomont = 10\dfrac{2}{3}=\dfrac{32}{3}\ miles

Now, the distance from Belmont to Carson is given by

Distance from Atherton to Carson - Distance from Atherton to Carson

13-\dfrac{32}{3}\\\\=\dfrac{39-32}{3}\\\\=\dfrac{7}{3}\\\\=2\dfrac{1}{3}\ miles

Hence, distance from Belmont to Carson is 2\dfrac{1}{3}\ miles

Graph the solution if the this inequality 4/9x-10>x/3-12
cupoosta [38]

You want to isolate the x-term from the constant term, so you can subtract x/3 and add 10. This gives you

... 4/9x -10 -x/3 +10 > x/3 -12 -x/3 +10

... 1/9x > -2 . . . . . . collect terms

Now, you can multiply by 9 to see the condition on x.

... 9(1/9x) > -2(9)

... x > -18


On the x-y plane, the graph of this will be a dashed line at x=-18, and the half-plane to the right of that line will be shaded.


On a number line, there will be an open circle at x=-18, and the number line to the right of that circle will be marked (bold, colored, shaded, whatever).

write a step by step proof. the givens are c is the midpoint of segment AB, and point c measures 10cm. prove AC=5cm plz help wil
Sliva [168]

Answer:

Step-by-step explanation:

GIRL! You should add diagrams to these types of questions. It would really help

That 10cm does not mean point C is 10cm. It means the line AB is 10 cm in total.

And since point C is the midpoint, which means that point C cuts the line AB in half, that makes AC = 5cm

wlad13 [49]

Step-by-step explanation:

100%=>$2,300

45%=>x

x=$2,300×45÷100=$1035

The pay left for other purposes

$2300-$1035=$1265

Or:

100%=>$2,300

55%=>x

x=$2,300×55÷100=$1265.
