What are the steps of 5x+1+12x-8=180?

Combine like terms: (5x+12x)+(1+−8)=180

17x- 7 = 180

Add 7 to both sides: 17x = 187

Divide by 17: x=11

Step-by-step explanation:

x = 11

Step-by-step explanation:

First put all the number on one side so its easier to add them up.

add the x's then do the regular numbers.

5x + 12x = -1 + 8 + 180

17x = 187

Then simplify it. so 17 can go into 187 11 times.

X = 11

Hope this helps, have a great day! :)

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

nope.   happens to me as well.
