5b + 9s = 28.75

10b + 10s = 47.5

Multiply all terms in equation #1 by 2.

10b + 18s = 57.5

Subtract both equations from each-other.

8s = 10

Divide both sides by 8.

s = 1.25

The cost of a soda is 1.25, and because we know this, we can plug it into either equation to solve for the cost of b, a burger.

5b + 9(1.25) = 28.75

5b + 11.25 = 28.75

Subtract 11.25 from both sides.

5b = 17.5

Divide both sides by 5.

b = 3.5

<h3>The price of a soda is $1.25.</h3><h3>The price of a burger is $3.5.</h3>

What is the common ratio between successive terms in the sequence? 2, –4, 8, –16, 32, –64, ... –2 –6 6 2
Nataly_w [17]

Answer:

-2

Step-by-step explanation:

You multiply each term by -2 to get the next term.

To find this for this sequence, divide the term on the right by the term on the left.

8 / -4 = -2              or          -4 * -2 = 8

-16 / 8 = -2             or         8 * -2 = -16

32 / -16 = -2           or         -16 * -2 = 32

-64 / 32 = -2           or         32 * -2 = -64

Which balloons traveled 11,595 feet farther than Martin? Draw a strip diagram and write a number sentence to solve the problem.
coldgirl [10]

From the table we notice that:

41507-29912=11595

This means that Diana traveled 11595 ft more than martin; this also means that Jake and Abby traveled more than that amount farther than Martin's balloon (since their distances are greater that Diana's distance)

Therefore, Abby's Jake's and Diana's balloons traveled 11595 ft farther than Martin's balloons.
