Answer:
this angle is a right angle(90°)
and one of the 2 angles is 30
3x+30=90
3x=90-30
3x=60
x=20
==> B
Since the sign is greater than or equal to, it’s a closed circle. I think that means it has a solution. Draw your number line than draw a circle on the 15th line. Make sure the circle is shaded in. Then draw a n arrow a cross the number line, pointing to the right because this equation is say the variable m is greater than or equal to 15
Answer:
First term: <u>A(1) = 5 </u>
Fourth term: <u>A(4) = 5 1/2 </u>
Tenth term: <u>A (10) = 6 1/2</u>
Step-by-step explanation:
Let's find the first, fourth and tenth terms of the arithmetic sequence described by the given rule:
A(n) = 5 + (n-1) (1/6)
First term:
A(1) = 5 + (1-1) (1/6)
A(1) = 5 + (0) (1/6)
<u>A(1) = 5 </u>
Fourth term:
A(4) = 5 + (4-1) (1/6)
A(4) = 5 + (3) (1/6)
<u>A(4) = 5 + 3/6 = 5 3/6 = 5 1/2 </u>(simplifying)
Tenth term
A(10) = 5 + (10-1) (1/6)
A(10) = 5 + (9) (1/6)
<u>A (10) = 5 + 9/6 = 6 3/6 = 6 1/2</u> (simplifying)
