RS=2x-8, ST = 11, RT = x+10

Answer:

$Equation~=~\Large\boxed{2x+3=x+10}$

$x~=~\Large\boxed{7}$

$RS~=~\Large\boxed{6}$

$RT~=~\Large\boxed{17}$

Step-by-step explanation:

Given information

$RS=2x-8$

$ST=11$

$RT=x+10$

Derived expression from the given information

Presumably, I think this is a combination of segments

$RS+ST=RT$

Substitute values into the given expression

$(2x-8)+(11)=(x+10)$

Combine like terms

The following is the expression

$\Large\boxed{2x+3=x+10}$

Subtract 3 on both sides

$2x+3-3=x+10-3$

$2x=x+7$

Subtract x on both sides

$2x-x=x+7-x$

$\Large\boxed{x=7}$

Substitute the x value into corresponding expressions to determine the final value

$RS=2x-8=2(7)-8=14-8=\Large\boxed{6}$

$RT=x+10=(7)+10=\Large\boxed{17}$

Hope this helps!! :)

The perimeter of UVW is 22 2/1. And VZ = 2 1/2. Find UW and VW.

Cerrena [4.2K]

UW and VW are the same so 9
22.5-4.5= 18 then divide the 18 by 2 so 9

Answer:

E (3,-1) D (-2, -2) G (-1, 3) F (3, 2)

Step-by-step explanation:

90 degrees = (y, -x)

that means you take the ordered pair you want to rotate and plug the x and y into the new spots.

for example, point E is at (1,3) so the point rotated 90 degrees is (3,-1)

Why can’t we add 5x and 11 together

Because they don’t have the same variables

-7=7d-8 solve for the variable d

kvv77 [185]

-7 = 7d - 8

Add 8 to both sides.

1 = 7d

Divide both sides by 7.
