julia-pushkina [17]

Answer:

121

Step-by-step explanation:

Since the pattern is that for each 1 driveway, she makes $11, we multiply 11*11 and get 121. We determine that each driveway makes her $11 by dividing the amount earned by the driveways shoveled.

I NEED YALL’S HELP <br> 2x+12=64<br> Step by step
OverLord2011 [107]

Answer:

2x + 12 = 64

x = 26 (mark brain if this helps and is correct)

Step-by-step explanation:

to solve equations with one missing variable we must use the order of operations of equality

step 1: use the subtraction property of equality meaning subtract each side of the equation

ex: 2x + 12 - 12 = 64 - 12   (2x = 52)

step 2: use the division property of equality meaning divide each side of the equation by 2

ex: 2x/2 = 52/2   (x = 26)

step 3: check your answer by putting 26 as x because that is our answer

2(26) + 12 = 64 (multiply 2 * 26)

52 + 12 = 64 (add 52 + 12)

64 = 64 (if both sides of the equation are the same number like 64 = 64 then your answer is true meaning that x is equal to 26)

The midpoint of segment QR is M(-2, 9). One end point of segment QR is Q(-8, 12). Find the coordinates of the other endpoint, R.
DanielleElmas [232]

Here,

The midpoint of segment QR is M

<u>m</u><u>(</u><u>-2</u><u>,</u><u>9</u><u>)</u> x3=-2,y3=9

<u>Q</u><u>=</u><u>(</u><u>-8</u><u>,</u><u>1</u><u>2</u><u>)</u>x1=-8,y1=12

R=x2,y2

we know that,

\tt{ m=\dfrac{Q+R}{2} } ⠀

So,

x3=\tt{\dfrac{x1+x2}{2} } ⠀

\tt{-2=\dfrac{-8+x2}{2}  } ⠀

\tt{-2×2=-8+x2  } ⠀

\tt{x2=8-4  } ⠀

\tt{x2=4  } ⠀

x2=4

now we find the y coordinate y2.

y3=\tt{\dfrac{y1+y2}{2} } ⠀

\tt{9=\dfrac{12+y2}{2}  } ⠀

\tt{9×2=12+y2  } ⠀

\tt{y2=18-12  } ⠀

\tt{y2=6  } ⠀

y2=6

<em>Now</em><em> </em><em>we</em><em> </em><em>get</em><em> </em><em>the</em><em> </em><em>two</em><em> </em><em>coordinate</em><em> </em><em>of</em><em> </em><em>R</em>

<em>so</em><em>,</em>

R=(x2,y2)=(4,6)
