Answer:
3. x=4
4. EF = 58
5. UW = 67
6. x=7
7. x=14, BC = 27, CD = 61, BD = 88
Step-by-step explanation:
3) 6x+1+x+7 = 36
7x + 8 = 36
7x = 28
x = 4
4) 47+3x+10 = 9x-39
57+3x = 9x-39
6x=96
x = 16
3(16)+10=58
the rest of them act similar to these two, in that the parts of the line add up to the given value of the total line. from there, solve for x and plug that value of x into the part you are trying to find.
