Answer:
2x+ 2.1 = 7.5
x=2.7
Step-by-step explanation:
The perimeter of an isosceles triangle with sides x and y is
2x+y = P
I put y as the single side since the question said y is the shortest side. It should say shorter sides if the two sides with the same length are smaller than the third.
We know y =2.1 and P = 7.5
Substituting these values in, we get
2x+ 2.1 = 7.5
Subtract 2.1 from each side
2x+2.1 -2.1 = 7.5 -2.1
2x= 5.4
Divide each side by 2
2x/2 = 5.4/2
x = 2.7 m

Answer: Hello! After being distributed, your answer should be 10x-20y+40z, hope this helps!
Step-by-step explanation: First multiply 5 and 2x and get 10x, then multiply 5 and 4y and get 20y, and lastly, multiply 5 an 8z and get 40z!
8,020 divided by 10 is 802.
Hope this helps!
