The perimeter of Stephanie’s triangle is half the perimeter of Juan’s triangle. Juan’s triangle is shown. Write a numerical expr

denpristay [2]

The perimeter of a triangle is the sum of all side lengths of the triangle. The numerical expression for the perimeter of Stephanie's triangle is: $\frac 12 \times 25$

Let the sides of Juan's triangle be x, y and z. So:

$x = 5 \\ y = 8\\ z = 12$

The perimeter (J) of Juan's triangle is calculated by adding all sides.

So:

$J =x +y +z$

This gives:

$J =5 + 8 + 12$

$J =25$

From the question, we understand that:

The perimeter (S) of Stephanie's triangle is half that of Juan.

This means that:

$S = \frac 12J$

Substitute 25 for J

$S = \frac 12 \times 25$

Hence, the numerical expression for the perimeter of Stephanie's triangle is: $\frac 12 \times 25$

Part A) $7(a+b)=7a+$

Using the distributive property

$7(a+b)=7a+7b$

therefore

the answer Part A is

$9-----> A$

Part R) $4(5+x)=20+$

Using the distributive property

$4(5+x)=20+4x$

therefore

the answer Part R is

$14-----> R$

Part Y) $3(2x+9)=6x+$

Using the distributive property

$3(2x+9)=6x+27$

therefore

the answer Part Y is

$4-----> Y$

Part S) $8(3x+1)=+8$

Using the distributive property

$8(3x+1)=24x+8$

therefore

the answer Part S is

$23-----> S$

Part O) $a(4+b)=+ab$

Using the distributive property

$a(4+b)=4a+ab$

therefore

the answer Part O is

$17-----> O$

Part E) $x(y+10)=+10x$

Using the distributive property

$x(y+10)=xy+10x$

therefore

the answer Part E is

$3-----> E$

Part I) $2(7x+4y)=14x+$

Using the distributive property

$2(7x+4y)=14x+8y$

therefore

the answer Part I is

$20-----> I$

Part D) $6(9+5x)=54+$

Using the distributive property

$6(9+5x)=54+30x$

therefore

the answer Part D is

$10-----> D$

Part W) $x(a+3b)=+3bx$

Using the distributive property

$x(a+3b)=ax+3bx$

therefore

the answer Part W is

$18-----> W$

Part E) $a(8x+2y)=8ax+$

Using the distributive property

$a(8x+2y)=8ax+2ay$

therefore

the answer Part E is

$7-----> E$

Part T) $0.5(4a+10)=2a+$

Using the distributive property

Part T) $0.5(4a+10)=2a+5$

therefore

the answer Part T is

$1-----> T$

Part R) $(2/3)(12+9y)=8+$

Using the distributive property

$(2/3)(12+9y)=8+6y$

therefore

the answer Part R is

$6-----> R$

Part O) $5x+5y=5(x+\ )$

$5x+5y=5(x+y)$

therefore

the answer Part O is

$13-----> O$

Part T) $9a+9b=9(\ +b)$

$9a+9b=9(a+b)$

therefore

the answer Part T is

$22-----> T$

Part W) $4m+4n=\ (m+n)$

$4m+4n=4(m+n)$

therefore

the answer Part W is

$16-----> W$

Part H) $ab+3a=a(b+\ )$

$ab+3a=a(b+3)$

therefore

the answer Part H is

$2-----> H$

Part E) $xy+15x=\ (y+15)$

$xy+15x=x(y+15)$

therefore

the answer Part E is

$11-----> E$

Part A) $bu+uv=\ (b+v)$

$bu+uv=u(b+v)$

therefore

the answer Part A is

$5-----> A$

Part F) $(2/5)m+(2/5)n=(2/5)( \ +n)$

$(2/5)m+(2/5)n=(2/5)(m+n)$

therefore

the answer Part F is

$12-----> F$

Part M) $(3/4)a+(3/4)b+(3/4)c=\ (a+b+c)$

$(3/4)a+(3/4)b+(3/4)c=(3/4)(a+b+c)$

therefore

the answer Part M is

$8-----> M$

Part S) $7ax+2ay=a(7x+\ )$

$7ax+2ay=a(7x+2y)$

therefore

the answer Part S is

$21-----> S$

They want to use the numbers 0-9

Count the number of timers a color shos on the wheel and assign 1 number for each time the color shows:

Blue shows 4 times so you would assign blue the numbers: 0,1,2,and 3

There are 3 yellows so you would assign that 4, 5, and 6

There are 2 reds so , 7 and 8

and 1 green would be 9

The question is in the pic please be specific

vichka [17]

Box 1) (LxW) 20x6=120
box 2) (LxW) 15x4=60
box 1 cost) (size of box x price of box) 120x1.25=150
box 2 cost) (size of box x price of box) 60x1.25=75
subtract 150 and 75 to get 75

answer: the company is saving $75 by choosing to make 50 of box 2 instead of 50 of box 1

hope this makes sense comment if you need more explanation
