Given
Write the next three terms of the arithmetic sequence. -13, -8, -3, 2, _, _, _
Procedure
-13+5=-8
-8+5=-3
-3+5=2
2+5=7
7+5=12
12+5=17
The sequence is -13, -8, -3, 2, 7, 12, 17
(-x)+2•4/2=6
-x+8/2=6
-x+8=12
-x=4
x=-4
20/3=6.666 repeating times that by 1.02 and you get 6.8. the real plane is 6.8m long.
Answer:
there is an infinet amount of answers.
Step-by-step explanation:
Answer:
The equation is p=34a+12, and a=7
Step-by-step explanation:
Perimeter is all of the sides added together
p=12a+6a+8+6a+8+10a-4
Combine like-terms
p=34a+12
Solve for a by making p equal to 250
250=34a+12
Subtract 12 from both sides
238=34a
Divide both sides by 34
7=a
