Can someone explain me how to solve this?
sesenic [268]

Answer:

X=12

Step-by-step explanation:

since it is an isosceles triangle opposite sides are congruent which means 7x+24=13x-48 you then would need to subtract either the whole numbers or the variables from each side so add 48 on each side it equals to 7x+72=13x then subtract 7x from 13x and you get 72=6x divide both sides 6/6=x, 72/6 Therefore x=12 HOPE that helped mark me brainiest pls

You conduct a quality check after running 350 parts 49 of the parts do not need this specifications what percent of the parts do
zepelin [54]

Answer:

14%

Step-by-step explanation:

<em><u>49 parts of 350 parts</u></em> do not need specifications...

= 49/350

So, 49/350 = x/100

= <u>49(100) = 350x</u>

= 4900 = 350x

= 4900/350 = x

x = 14%

Why is the answer to a subtraction problem called the difference...
lana [24]
Maybe because you're finding the "difference" between the two numbers. We could also question why the answer to an addition problem is called sum.
Well, 'sum'body said that's what they should be called a long time ago, that's why we're using that term to call them now.
