First combine like terms ( x's go with x's), so subtract 2x to both sides and you get:

5+ (3x-2x) = 6 + (2x-2x)

5 + x = 6

Isolate x by bringing 5 to the other side by subtraction

(5-5) + x = (6-5)

x = 1

Hope this helped!

Olive and Ryan have picture frames with the same perimeter. Olive’s picture frame has a width 1.25 times the width of Ryan’s pic

Mashcka [7]

Step-by-step explanation:

x=1.25y

perimeter= 2width+2length

olivias p=ryan's p so:

Ryan's p= 2*1.25 Ryan's width+ 2Olivias length

Olivias length= (2,5Ryan's width- Ryan's p)/2

to solve the question we need to recall one of the most important theorem of circle known as two tangent theorem which states that tangents which meet at the same point are equal that is being said

FA=AI=17
CH=CG=2.5

since $\rm BA=FA+FB$ and it's given that FA and BA are 17 and 29 FB should be

$\rm 29=17+FB$

therefore,

$FB=29-17=\boxed{12}$

once again by two tangent theorem we acquire:

$FB=BH=\boxed{12}$

As BC=BH+CH,BC is

12+2.5
$\boxed{14.5}$

likewise,AD=AI+DI so,

21=17+DI [AD=21(given) and AI=17 (by the theorem)]

thus,

DI=21-17= $\boxed{4}$

By the theorem we obtain:

DI=DG=4

Similarly,DC=DG+CH therefore,

DC=4+2.5= $\boxed{6.5}$

Now finding the Perimeter of ABCD

$P_{\text{ABCD}}=\text{AB+AD+BC+DC}$

substitute what we have and got

$P_{\text{ABCD}}=\text{29+21+14.5+6.5}$

simplify addition:

$P_{\text{ABCD}}=\boxed{71}$

hence,

the Perimeter of ABCD is 71
