-15/-18=10/x
what is X?

Answers

Answer 1

Answer:

12

Step-by-step explanation:

(-15)/(-18) = 10/x cross multiply expressions

-15x = -180 since both sides are negative we can write without the sign

15x = 180 divide both sides by 15

x = 12

Answer 2
The answer you are looking for is 12

Answers

Answer:

length= 35 feet and width= 10 feet

Step-by-step explanation:

You are given the perimeter of the rectangular deck is

90 feet.

2 x length + 2 x width = 90 You are also given that the deck's length is 5 feet less than 4 times it's width. That is length = 4 x width - 5

Those two equations are your system of linear equations. The second equation can be plugged into the first equation. This gives us an equation entirely in terms of width.  

2x (4 x width - 5) + 2 x width =90

Distribute the 2 though

8 x width - 10 + 2 x width = 90

Combine like terms with width.

10 x width - 10 = 90

Add 10 to both sides.

10 x width = 100

Divide both sides by 10 width = 100

Now you can plug width into your original equation for length above. Recall: length = 4 x width - 5

Length = 4 x 10 - 5

Length = 40 - 5

Length = 35

length is 35 feet and width is 10 feet

5. Using the equation y=2x+5, construct a table and graph the line

Answers

Step-by-step explanation:

What you are going to do is for each value of x (which is the value to the right on the table) you will find the Y value.

So for X = 0

y = 2(0)+5 = 5

x = 1

y = 2(1)+5 = 7

x = 3

y = 2(3)+5 = 11

x = 5

y = 2(5)+5 = 15

x = 10

y = 2(10)+5 = 25

Now for what you do is place the correspanding value into the graph.

(x,y) = (0,5), (1,7), (3,11),(5,15),(10,25)

Answer: See the graph below.

A chef needs to choose a pan that will allow food to cook as quickly as possible for a special recipe and has decided that he will use one of three pans. Each pan has the same dimensions and design but is made of a different type of metal. The chef will design an experiment that will test and rank the thermal conductivity of the pans by cooking a hamburger patty to an internal temperature of 170 °F in each pan on the same stove burner. The thermal conductivity is the rate of transfer of energy in the form of heat over a period of time through a material.
Describe how thermal conductivity can be measured and compared for each of the pans.

4) Not Similar. 13/16 does not equal 16/21.

5) Not Similar. 28/48 and 42/36 do not reduce to the same value.

6)No. The angles are not the same.

In other words, ifthe corresponding sides reduce down to the same value, they are similar.

Answers

Answer:

All Real Numbers

Step-by-step explanation:

First, use the distributive property to expand everything:

8v-6=10v-6-2v

Then, combine like terms:

8v-6=8v-6

Then, subtract 8v from both sides to isolate the variable:

0-6=-6

-6=-6

Any real number you substitute with v will make the equation always true, as -6 always is equal to -6. Therefore, the answer is All Real Numbers.

Alll that equals -6 hope this helps
