What is the value of x?

Answers

Answer 1

Value of x is used to consider unknown value. The letter “x” is commonly used in algebra to indicate an unknown value. It is referred to as a “variable” or, in some cases, a “unknown.” In x + 2 = 7, x is a variable

Answer 2

Answer:

A triangle is 180 degrees and you have a 30 and 50 angle so the third angle should equal 100. so the answer should be 45 and here's why

Step-by-step explanation:

Subtract 10 from both sides

2x+10=100

2x+10-10=100-10

Simplify

Subtract the numbers

2x=90

Divide both sides by the same factor

2x=90

2x/2 = 90/2

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

x=45

Step-by-step explanation:

You first divide the shape into two parts; into a square and a rectangle. Then you multiply 5 x 5, (representing the square) becomes 25. Then you multiply 10 x 5, (representing the rectangle) becomes 50. Now you add 25 and 50 to get the answer 75.

75m
Divide the shape then multiply 5x5 and 10x5 to get 25 and 50. Add them together to get 75m

using addition and subtraction.

Note:

To get from a small number to a big number will use addition and

to get from a big number to a small number will use subtraction.

from IN: 11 to OUT: 26

11 + ? = 26

Compare the two numbers by making the difference 26 - 11= 15

11 + 15 = 26

Rule: Add 15

HELP! 6th-grade math PLEASE HELP!

Answers

first, find the area of prism ll by multiplying 5/2, 9/4, and 2

this will result in 45/4, or 11.25

now, you have to figure out how many small cubes will fit inside prism ll

we know that the side lengths of the small cubes are 1/4, and since cubes have equal side lengths, you can multiply 1/4, 1/4, and 1/4 to find the area

this will result in 1/64

divide the area of prism ll, 11.25, by the area of the small cubes, 1/64, to get 720

then, do the same thing for prism l

multiply 7/4, 3/2, and 5/4 to get 105/32

divide this by the previous 1/64 to get 210

lastly, to determine how many more small cubes can fit into prism ll, subtract 210 from 720

720-210=510

final answer: 510 cubes

hope this helped!!

Can anyone solve this?

Answers

Answer:

324 inches squared

Step-by-step explanation:

The question is most likely asking for the surface area of the rectangular prism.

The Formula for this is:

2(wl+hl+hw)

h = 6in

w = 5in

l = 12in

Plug in the varibles:

2( 5*12 + 6*12 + 6*5)

Simplify:

2( 60 + 72 + 30) =

2(162) =

324

So the answer is 324 inches squared!

Hope this helps! :)

Answer:

The surface area of the rectangular prism is: 324

The volume of the rectangular prism is: 360

Step-by-step explanation:

Surface area is calculated with the formula:

2(wl + hl + hw)

w*l = 6*12 = 72

h*l = 5*12 = 60

h*w = 5*6 = 30

Now add up 72, 60, and 30.

72+60+30 = 162.

This leaves us with the equation:

2(162)

So, we multiply 2 and 162 to get the surface area.

2*162 = 324.

For the volume, we multiply the length, width, and height altogther.

l*w*h

So, we plug in the values, and multiply:

12*6*5 = 360

The volume is 360 in^3

Stephanie is helping her band collect money to fund a field trip.
The band decided to sell boxes of chocolate bars. Each bar sells
for $1.50 and each box contains 20 bars. Below is a partial table
of monies collected for different numbers of boxes sold.
Boxes Sold (b) Money Collected (m)
1 $30
2 $60
3 $90
4 $120
5 $150
6 $180
7 $210
8 $240

1.) Complete the table above for all values of m.

2.) Which is the independent variable?

3.) Which is the dependent variable?

4.) Write an equation for the amount of money, m, that will be
collected if b boxes of chocolate bars are sold.

5.) Graph the equation using the ordered pairs from the table
above.
(Don’t forget to label your axes and increments!)

6.) How much money will be collected if 100 boxes of chocolate
bars are sold?

7.) The band collected $1530 from chocolate bar sales. How
many boxes did they sell?

Answers

Answer:

O P=20($1.50)

They will make $3,000 if they sell 100 boxes of chocolates

Step-by-step explanation:

It is multiplication because it is $1.50 per each chocolate bar, and since there is 20 per box, we need to find the profit for the entire box

using that info, we find that each box of chocolates is 30 dollars

multiplied by 100 boxes is $3000.
