white chocolate costs $2.00 per bar, and dark chocolate costs $2.50 per bar. If you buy 15 bars of chocolate for $34, how many of each bar did you buy?

Answers

Answer 1

Answer:

7 white and 8 dark bars

Step-by-step explanation:

x white bars

15-x dark bars

cost of white bars is 2 * x

cost of dark bars is 2,5 * (15-x)

Write an equation

2x + 2,5 * (15-x) = 34

2x + 37,5 - 2,5x = 34

-0,5 x = - 3,5

x = 7

So we have x = 7 white bars

and 15 - x = 15 - 7 = 8 dark bars

5. Find 7568 more than 16498.​

Answers

just 7,568+16,498? which would equal 24,066

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.

To solve the system of linear equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms. When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 with his graphing

A. calculator, but he could only see one line. Why is this?
B. because the system of equations actually has only one solution
C. because the system of equations actually has no solution

72 is  30 percent of 240  because

240* x/100 = 72

24000x=7200

x=.3

We can check by doing

240*.3= 72

there is a 30% decrease

Dan is stocking up on AA and AAA batteries. He bought 10 packages of batteries for a total of 72 batteries. The AA batteries are sold in packages of 6, and the AAA batteries are sold in packages of 8. Write, but do not solve, a system of equations that can be used to find how many packages of each type of battery Dan bought.

Answers

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

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

One coffee and two slices of cake cost 8 dollars in total. Two coffees and 3 slices of cake cost 14 dollars in total. What are the individual prices of one coffee and of one slice of cake?

Answers

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.

What is Equation?

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.

A scientist mixes x liters of water into a container that had 10 liters of a mixture that is 12% salt and 88% water. The function f(x)=

Answers

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
