1/3 + -7/4

I am very confused

Answer:

Step-by-step explanation:

Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

X COULD BE 2 OR 7

Step-by-step explanation:

Answer:

A. x= -3

Step-by-step explanation:

firstly collect all the terms . then move the term so it'd look like 5x+14 = -2x - 7 then calculate it then it would look like this : 5x+2x = -7 -14 after you move the terms you again calculate it and then the finish product would look like this : 7x = -21 so after you get that you divide by both sides and the answer is -3 . (im sorry if that don't make sense) but the answer is A.

Answer:

9,945,936,000.

Step-by-step explanation:

This is the number of permutations of 6 letters from 26 multiplied by number of permutations of 3 odd digits between 0 and 9.

The total number of odd digits between 0 and 9 are 1,3,5,7,9 = 5.

So the number of choices are

26P6 * 5P3.

=  26!/(26-6)! * 5!/ 2!

= 26!/20! * 5!/2!

= 165765600 * 60

= 9945936000.

Answer:

They use 741 dollars

Step-by-step explanation:

Write 65% as

65/100

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have

65/100 of 1140 = 65/100× 1140

Therefore, the answer is 741

If you are using a calculator, simply enter 65÷100×1140 which will give you 741 as the answer.

Amount of budget spend on costume is $741

Given that;

Total budget of student firm = $1140

Percentage of budget used = 65%

Find:

Amount of budget spend on costume

Computation:

Amount of budget spend on costume = Total budget of student firm × Percentage of budget used

Amount of budget spend on costume = 1,140 × 65%

Amount of budget spend on costume = 1,140 × 0.65

Amount of budget spend on costume = $741

Answer:

The yearly value of the card 25 years later is $16.93.

Step-by-step explanation:

You can use the following formula to find the future value:

FV=PV(1+r)^n

FV= future value

PV= present value= 5

r=rate= 0.05

n=number of periods of time= 25

Now, you can replace the values in the formula:

FV=5(1+0.05)^25

FV=5(1.05)^25

FV=16.93

According to this, the answer is that the yearly value of the card 25 years later is $16.93.

Answer:

27°C

Step-by-step explanation:

The temperature on February 9th 1934 = -15°C

The next day the temperature rose 42 degrees.

We need to find an expression for the temperature on February 10th.

February 10th temperature = -15 + 42

= 27°C

So, the temperature on February 10th is 27°C.

Answer: it would be 42+(-15)

Answer:

Step-by-step explanation:

Given the coordinate points (3, 2) and (3, 6), to get the x intercept, we need to first get the equation of the line passing through the points

Form the coordinate, we can see that the line passes through the points x = 3 on both coordinates. This shows that the line is a horizontal line cutting the x axis at x =3. Hence the x-intercept for the line will be 3

Answer:

0.8 gallons of red paint or 4/5 gallons of red paint

Step-by-step explanation:

Jan and Jerome are mixing red paint with white paint to make pink paint, in the ratio of 4 parts red to 5 parts white. How many gallons of red paint should they mix with 1 gallon of white paint? Express your answer as a common fraction

How many gallons of red paint should they mix with 1 gallon of white paint?

Let parts be represented as x

Hence:

Red : white

4 : 5

4/5 = x/ 1

We cross Multiply

5x = 4

x = 4/5

x = 0.8 gallons of red paint or 4/5 gallons of red paint

Answer:

Number of vegetarian wraps = 80

Number of chicken wraps = 37

Step-by-step explanation:

Let

Number of vegetarian wraps = x

Number of chicken wraps = y

x + y = 117 (1)

x + 1.5y = 135.50 (2)

Subtract (1) from (2) to eliminate x

1.50y - y = 135.50 - 117

0.50y = 18.50

y = 18.50/0.50

y = 37

Substitute y = 37 into (1)

x + y = 117 (1)

x + 37 = 117

x = 117 - 37

x = 80

Number of vegetarian wraps = 80

Number of chicken wraps = 37

Answer:

$231,813

Step-by-step explanation:

The estimated expenses after 6 months is $231,812.5

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

Expense = 4,000 + 20,000 x [tex](1.5)^t[/tex]

Now, for t= 6 months

Expense = 4,000 + 20,000 x [tex](1.5)^6[/tex]

Expense = 4,000 + 20,000 x 11.390625

Expense = 4,000 + 2,27,812.5

Expense = 231,812.5

Hence, The estimated expenses after 6 months is $231,812.5.

Answer:

0.166

Step-by-step explanation:

Bought 18 cards for $2.99, so you can write it like this:

18 = 2.99

Since you want to find the value of one card, u could write that like this:

1 = x  (where x is the unknown value of 1 card)

To get from 18 to 1, you divide by 18, so to get to 2.99 to x you must divide by 18 as well.

So 2.99/18 = 0.166

therefore x = 0.166

So you can say that each card costs about 17 c
