⎩ ⎪ ⎪ ⎨ ⎪ ⎪ ⎧ ​ b(1)=−2 b(n)=b(n−1)−7 ​ Find the 3 rd 3 rd 3, start superscript, start text, r, d, end text, end superscript ter
vitfil [10]

Answer:

-16

Step-by-step explanation:

Given the sequence:

b(n)=b(n−1)−7, where b(1)=−2

b(2)=b(2−1)−7

=b(1)−7

=-2-7

b(2)=-9

Therefore, the 3rd term of the sequence

b(3)=b(3−1)−7

=b(2)-7   (Recall b(2)=-9 from above)

=-9-7

b(3)=-16

The 3rd term of the sequence is -16.

Fran has a poster that measures 3/4 square yard in area the length of the poster is 1/3 yard what is the width of the poster
Harrizon [31]

Answer:

9/4 yards

Step-by-step explanation:

A poster is a rectangle.

Area of rectangle = Length × Width

Given:

Area = 3/4 yd

Length = 1/3 yd

Substitute the given values to the equation.

3/4 = 1/3 × w

3/4 = 1/3w

3/4 ÷ 1/3 = w

3/4 × 3/1 = w

9/4 = w
