what is this type of question called and how can i solve it?

Answer:

[tex]\frac{3x+4}{x+5}[/tex]

Step-by-step explanation:

Given

[tex]\frac{2x+7}{x+5}[/tex] + [tex]\frac{x-3}{x+5}[/tex]

Since both fractions have a common denominator then add the numerators, placed over the common denominator.

= [tex]\frac{2x+7+x-3}{x+5}[/tex]

= [tex]\frac{3x+4}{x+5}[/tex]

Answer:

The answer is

[tex] \frac{3x + 4}{x + 5} [/tex]

Step-by-step explanation:

We can do this by using the denominators.

[tex]then \\ \frac{2x + 7}{x + 5} + \frac{x - 3}{x + 5} \\ = \frac{2x + 7 + x - 3}{x + 5} \\ = \frac{3x + 4}{x + 5} [/tex]

Step-by-step explanation:

that is the formula for calculating pythagoras

16498 + 7568 = 24066.So, the correct answer is 24066 To find 7568 more than 16498, we can perform the following calculation:

16498 + 7568 = 24066.

We can perform sum via many ways:

Place value: This approach adds numbers by using their place values. For instance, we would arrange the numbers according to their decimal places and add each place value column separately to get the sum of 23 and 45. 68 would be the total.

Comparable to place value addition, but with the integers arranged in columns, is the column addition technique. For adding higher numbers, this can be useful. For instance, we would arrange the numbers in columns and add each column separately to equal 234 + 567. 801 would be the total.

Mental addition: To add numbers quickly, utilize this technique. For instance, we may consider about 23 as 20 + 3 and 45 as 40 to add 23 and 45.

Answer:

Step-by-step explanation:

coffee=c

cakes=d

c+2d=8

2c+3d=14

c=8-2d

2(8-2d)+3d=14

16-4d+3d=14

-d=-2

d=2

c+4=8

c=4

coffee=4 dollars each

cakes=2 dollars each

The price of coffee is $4 and price of slice of cake is $2.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

One coffee and two slices of cake cost 8 dollars in total.

Two coffees and 3 slices of cake cost 14 dollars in total.

let the price of coffees sold be x

let the price of slices of cake sold be y

Then, the system of equations are

x+ 2y = 8

2x+ 3y = 14

On solving

2(8- 2y)+ 3y= 14

16 - 4y + 3y= 14

-y= -2

y= 2

and, x = 8- 2(2)= 8- 4= 4

Hence,  price of coffee is $4 and price of slice of cake is $2.

Answer:

x + y = 10

6x + 8y = 72

Step-by-step explanation:

Number of packages = 10

Total batteries = 72

For AA:

batteries per package = 6

Let number of packages = x

For AAA:

batteries per package = 8

Let number of packages = y

Number of AA packages + number of AAA packages = 10

Sum of AA + sum of AAA equals 72 batteries

x + y = 10

6x + 8y = 72

Answer:Answer:

x + y = 10

6x + 8y = 72

Step-by-step explanation:

Number of packages = 10

Total batteries = 72

For AA:

batteries per package = 6

Let number of packages = x

For AAA:

batteries per package = 8

Let number of packages = y

Number of AA packages + number of AAA packages = 10

Sum of AA + sum of AAA equals 72 batteries

x + y = 10

6x + 8y = 72

Answer:

30% and $30

Step-by-step explanation:

Well  240-168 is 72

72 is  30 percent of 240  because

240* x/100 = 72

24000x=7200

x=.3

.3 is percentage is 30%

We can check by doing

240*.3= 72

there is a 30% decrease

Next question

If the total price of something is 31.20 with a 4% tax we do

x * .04 + x = 31.20

because 4% added to the price of that object is 3.20

1.04x = 31.20

x= 30

we can check by doing

30*.04+ 30= 31.2

Step-by-step explanation:

We are given:

[tex]1-5|n-9|=-74[/tex]

Subtract 1 from both sides:

[tex]-5|n-9|=-75[/tex]

Divide both sides by -5:

[tex]|n-9|=15[/tex]

By definition of absolute value:

[tex](n-9)=15\text{ or } -(n-9)=15[/tex]

Solve for each case:

[tex]n=24\text{ or } n=-15+9=-6[/tex]

Answer:

110 liters of water

Step-by-step explanation:

The computation of the number of liters of water added is shown below:

Let us assume the x be the liters of water

f(x) represents the salt percentage in the mixture

Given that

f(x) = 1.2 ÷ x + 10

f(x) = 1% = 1 ÷ 100  = 0.01

Now out the f(x) value in the above equation

0.01 = 1.2 ÷ x + 10

x + 10  = 1.2 ÷ 0.01

x + 10 = 120

x = 110 liters

Step-by-step explanation:
