<h3>Answer:  d = -8</h3>

==========================================================

Explanation:

Pick any term that isn't the first term. Then subtract off the previous term. If we get the same result each time, then the sequence is arithmetic, and that result is the common difference.

  • term2 - term1 = 2-10 = -8
  • term3 - term2 = -6-2 = -8
  • term4 - term3 = -14-(-6) = -14+6 = -8
  • term5 - term4 = -22-(-14) = -22+14 = -8

We get -8 each time, so the sequence is arithmetic with common difference d = -8. It says to add -8 to each term to get the next term. This is the same as subtracting 8 from each term to get the next term.

Note how:

  • 10-8 = 2
  • 2-8 = -6
  • -6-8 = -14
  • -14-8 = -22

Directions: Find each missing measure. please help me find T and U
adoni [48]

Answer:

m∠U = 54°

m∠T = 72°

Step-by-step explanation:

The triangle shown is an isosceles triangle. Therefore, the 2 sides and angles that are marked must be congruent:

m∠S = m∠U

m∠S = 54°

m∠U = 54°

All angles in a triangle add up to 180°:

m∠S + m∠U + m∠T = 180°

54° + 54° + m∠T = 180°

108° + m∠T = 180°

m∠T = 72°

Answer:

0.25

Step-by-step explanation:

Average means \frac{total \: number}{number \:  \: of  \: \: individuals}

According to the formula, each student in Mr. Goldwasser's class read

\frac{66}{24}  = 2.75

books on average, and each student in Mr. Welch's class read

\frac{65}{26}  = 2.5

books on average.

Therefore, the answer will be

2.75 - 2.5 = 0.25

Help me please!!!!!!!!!!!!

Answer: 0.25g<2.50.... g<10

Step-by-step explanation: Let us say that the number of gumballs bought is represented by the variable g. In this case, the question is asking how many gumballs can be bought without surpassing the price of $2.50. We know that each gumball is $0.25, therefore the number of gumballs we buy times $0.25 has to be less than $2.50. Hence, the inequality would be 0.25g<2.50. If we were to solve this then g<2.50/0.25-----> g<10. In conclusion, the number of gumballs you can buy has to be less than 10. Thank you!
