Answer:
DC = 2
Step-by-step explanation:
The wrong equation was used.
The right equation to use based on the midsegment theorem of a trapezoid is:
MN = ½(AB + DC)
MN = 8
AB = 14
Substitute
8 = ½(14 + DC)
Multiply both sides by 2
8*2 = ½(14 + DC)*2
2*8 = 14 + DC
16 = 14 + DC
16 - 14 = 14 + DC - 14
2 = DC
DC = 2
Answer:
64 times 7.5 and you will get your answer
Step-by-step explanation:
16*4=64
64*7.5=x
x is what you need to find
Answer:
38.5
Step-by-step explanation:
Lets say, first number = x
Second number = 3x+7
Total = 49
(x)+(3x+7)= 49
4x+7 = 49
4x = 42
x = 42/4
x= 10.5
x= 10.5
3x+7 = 3(10.5)+7 = 38.5
Hope this helps!!
Answer:
Step-by-step explanation:
4x+8=6x-1
<u>-4x . =-4x .</u>
8 = 2x-1
<u>-1+8=2x-1+1 </u>
7=2x
7/2= 2x/2
3.5=x
