I believe the answer is a trapezoid.
Hope this helps!

For a sequence to be arithmetic, it means that the common difference between the terms must be a constant. We see here that from the previous term to the next, it always increases by a constant 3 if the pattern were to continue. That means our sequence is arithmetic with a common difference of 3. (+3+3+3, yes)
The answer is B
Hope it helps!!
A straight line is 180°. The angles of QRT (2x + 33) and TRS (5x - 21) make up the 180° angle. So you can do:
∠QRT + ∠TRS = 180°
(2x + 33) + (5x - 21) = 180°
2x + 33 + 5x - 21 = 180 Combine like terms
7x + 12 = 180 Subtract 12 on both sides
7x = 168 Divide 7 on both sides
x = 24
Now that you found x, you can find the angles of QRT and TRS.
m∠QRT = 2x + 33
= 2(24) + 33
= 48 + 33
∠QRT = 81°
m∠TRS = 5x - 21
= 5(24) - 21
= 120 - 21
∠TRS = 99°
Answer:
use a ratio
Step-by-step explanation:
you work 10 hours and make $25. How much do you earn per hour? (this is your unit rate.)
<u>10 hours</u>
$25
divide and you get an answer of $2.50 per hour
to check your answer work the problem backwards, take $2.50 times 10 hours = $25
