Answer: 86

Step-by-step explanation:

Since we want to know the number of walking plans that she will do on the 15th day, we have to use 14 days in our calculations as the first day isn't included.

Therefore, the equation to solve this will be:

= 2 + 6d

where,

d = number of days = 14 days

= 2 + 6d

= 2 + 6(14)

= 2 + 84

= 86

The glass fish tank does not have a cover. Find the total area of the glass panels used to make the tank.
pogonyaev
You will find the area of the 5 surfaces made of glass. There is a front, back, 2 sides, and the bottom. Each face is in the shape of a rectangle, so you will multiply the length by the width.
1. Front- 24 x 27 =648
Back-24 x 27 = 648
2. Side- 21 x 27 =567
Side - 21 x 27 = 567
3. Bottom - 21 x 24 = 504

Add all these together for your total amount of glass needed. The answer is 2934 square cm of glass.

Explain how to solve this, step by step?

Answer:

The cost of  chair is \$260

The cost of  a lamp is \$65

The cost of  a table is \$237

Step-by-step explanation:

Let

x----> the cost of  chair

y----> the cost of  lamp

z----> the cost of table

we know that

x+y+z=562 ----> equation A

x=4y -----> y=x/4 -----> equation B

z=x-23 ------> equation C

substitute equation C and equation B in equation A and solve for x

x+(x/4)+(x-23)=562

(9/4)x=562+23

(9/4)x=585

x=585*4/9=\$260

Find the value of y

y=260/4=\$65

Find the value of z

z=260-23=\$237

therefore

The cost of  chair is \$260

The cost of  a lamp is \$65

The cost of  a table is \$237
