- 1/2 - 2/3v = 4/5 please help

- 1/2 - 2/3v = 4/5 Please Help

Answers

Answer 1

Answer:

-39/20 (decimal is -1.95)

Step-by-step explanation:

First, you have to isolate the variable term (-2/3v). You can do this by moving -1/2 to the other side. Then, the right side would be 4/5+1/2. Make this side common by changing the denominators to being the same thing (8/10+5/10=13/10). Now, we know that 13/10 is equal to -2/3v. You can then divide both sides by -2/3 to get v. If you're lazy like me, just use a calculator to divide 13/10 by -2/3. What you get then is your answer!

Hope this helps! Please mark me as brainliest!

Answer 2

Answer:

v = - 39/20

Step-by-step explanation:

-1/2 - 2/3v = 4/5

-2/3v= 4/5 + 1/2

-2/3v = 8/10 + 5/10

-2/3v = 13/10

v = 13/10 * -3/2

v = - 39/20

Hope this helps!

Please define the following terms:

condensation, pressure, temperature, thermal energy.

Answers

Answer:

Step-by-step explanation:

Condensation-water which collects as droplets on a cold surface when humid air is in contact with it: the conversion of a vapor or gas to a liquid:

Pressure-is the force applied perpendicular to the surface of an object per unit area over which that force is distributed

Temperature-Temperature is a physical quantity that expresses hot and cold. It is the manifestation of thermal energy, present in all matter, which is the source of the occurrence of heat, a flow of energy, when a body is in contact with another that is colder.

Thermal energy-Thermal energy refers to several distinct physical concepts, such as the internal energy of a system; heat or sensible heat, which are defined as types of energy transfer (as is work); or for the characteristic energy of a degree of freedom in a thermal system

Kato must write 60 percent of a 20-page report by tomorrow. Kato wants to determine the number of pages that he needs to write by tomorrow. Kato’s work is shown below.

Step 1: Write 60 percent as a ratio. part/whole = 60/100
Step 2: Write an equivalent ratio that has the answer in the numerator and 20 in the denominator.
Step 3: 100 divided by 20 = 5
Step 4: 60(5) = 180

What mistake did Kato make?
In Step 1, Kato should have written the ratio as 100/60.
In Step 2, Kato should have put 20 in the numerator.
In Step 3, Kato should have multiplied 100 by 5.
In Step 4, Kato should have divided 60 by 5.

Phone A
Phone B
Phone C
Phone D

Answers

Answer:

Using quick mental math, we can do 8% of 10 to get 0.8, which is close to the value of 0.0845*10. Also fairly quick is moving the decimal point over 1 spot to the right and we go from 0.0845 to 0.845 and that rounds to 0.8 when rounding to one decimal place. Recall that 8.45% = (8.45/100) = 0.0845

If you want to compute out the four results with a calculator, then it would look like this:

0.0845*20 = 1.69

0.0845*25 = 2.1125

0.0845*10 = 0.845

0.0845*18 = 1.521

and this shows that no other result (but choice C) is close to 0.8

So that's why the answer is choice C

Answers

Answer:

27

Step-by-step explanation:

180-(90+33)=57

90-57=33

180-(120+33)=27

Answer:

? = 27

Step-by-step explanation:

Keep in mind that all angles in a triangle equal 180

Add up all the known angles in triangle 1

90 + 33 = 123

and subtract it by 180 to find the third angle

180 - 123 = 57

then subtract 57 by 90 to find the other side of 90 degree angle the to triangles share

90 - 57 = 33

next add the angle we just found by 120

120 + 33 = 153

finally subtract 180 by 153

180 - 153 = 27

Steve had $140.50 dollars. He loaned $50 dollars to a friend, spent $31.25 dollars, and received his $80.75 dollars paycheck from work. How much money does he have now? Show your work

Answers

Answer:

Steve has a total of $140.

Step-by-step explanation:

At first, we know that Steve has $140.50. Next, he loaned $50 to a friend. This tells us that this money went out of his account.

140.50 - 50 = $90.50

So now, Steve has only $90.50 left.

Then, he spent $31.25. This also tells us that his went out of his account, so we must subtract it.

90.50 - 31.25 = $59.25

Now, Steve has $59.25 left.

Finally, Steve received an $80.75 paycheck from work. This tells us that this money went in to his account.

59.25 + 80.75 = $140

Therefore, Steve now has a total of $140.

A square has a perimeter of 36millimeters.
What is the area of the square?
square millimeters

Answers

i think it’s gonna be 144 mm, the area of a square is equal to one side length times 4, in this case it would be 36x4 which equals 144 :)
If a square has a perimeter of 36 mm, then all four sides were added. 36/4 = 9 mm
So 1 side equals to 9 mm.
As in area, one side times another side will be your area.
So 9 x 9 = 81

So your answer will be 81 square mm.

Step-by-step explanation:

Option C is the correct answer.

What is an expression?

An expression is a combination of numbers, variables, functions such as addition, subtraction, multiplication or division, etc.

We have,

Three box sizes:

Small, Medium, and Large.

The volume of the medium box is x.

The volume of the medium box = x ____(1)

The small box has half the volume of the medium box.

The volume of the small box = x/2 _______(2)

The large box has twice the volume of the medium box.

The volume of the large box = 2x _____(3)

Combining (1), (2), and (3) we get,

= x + x/2 + 2x

= (2x + x + 4x) / 2

= (7/2)x

= 3.5x

Thus the expression that shows the combined volume of the three boxes is 3.5x.
