Answer:

5*x=15;x=3

Step-by-step explanation:

a)Let x represent the number of miles ran each day

b)Number of days*Number of miles=number of miles ran each day (5*x=15)

c)Draw algebra tiles to model the equation. Carolina ran <u>3 miles</u> each day.

P.S. This is not part of the question but I am just letting you know that this (*) symbol that looks like a snow flake means multiplication.

What radius of a circle is required to inscribe a regular hexagon with an area of 210.44 cm2 and an apothem of 7.794 cm
alekssr [168]
We know that

[area of a regular hexagon]=6*[area of one <span>equilateral triangle]
</span>210.44=6*[area of one equilateral triangle]
[area of one equilateral triangle]=210.44/6-----> 35.07 cm²

[area of one equilateral triangle]=b*h/2
h=7.794 cm
b=2*area/h------> b=2*35.07/7.794------>b= 9 cm

the length side of a regular hexagon is 9 cm
<span>applying the Pythagorean theorem
</span>r²=h²+(b/2)²------>r²=7.794²+(4.5)²------> r²=81--------> r=9 cm

<span>this last step was not necessary because the radius is equal to the hexagon side------> (remember the equilateral triangles)
</span>
the answer is
the radius is 9 cm

Since x=8y, subsitute 8y for x in other equation

y=6x-11
y=6(8y)-11
y=48y-11
minus y both sides
0=47y-11
add 11 to both sides
11=47y
divide both sides by 47
\frac{11}{47}=y
subsitute taht for y to find x

x=8y
x=8(\frac{11}{47})
x=\frac{88}{47}



x=\frac{88}{47}
y=\frac{11}{47}
in (x,y) form
(x,y)
(\frac{88}{47},\frac{11}{47})
