Seven times a number minus the number is -48. Find the number.
A. the number is -8
B. the number is 8
C. the number is 6

Answers

Answer 1

Answer:

x = -8

Step-by-step explanation:

let's say the number is equal to x; seven times the number is 7x;

then it says minus the number so 7x-x is equal to -48

7x-x=-48; combine the x's

6x = -48; now divide by 6

x = -8

Answer 2

Answer:

The anwser would be A: -8

Step-by-step explanation:

7 x -8 = -56

-56 - (-8) = -48

How many solutions does this system of equations have?

A. No Solutions
B. 2
C. 1
D. An infinite number of solutions

Answers

Answer: D) infinitely many solutions

===================================================

Explanation:

Let's solve the first equation for y

4x - 2y = 6

4x-6 = 2y

2y = 4x-6

y = (4x-6)/2

y = (4x/2) - (6/2)

y = 2x - 3

After doing so, we see that 4x-2y = 6 is equivalent to y = 2x-3

Therefore, the original system of equations is effectively listing the same equation twice (one has a different form compared to the other).

Both equations in this system produce the same graph, which leads to infinitely many solutions. All solutions are on the line y = 2x-3.

You can say that all solutions are in the form (x, 2x-3) where x is any real number you want.

-------------------------------

Here's another approach using substitution

4x - 2y = 6 ... start with the first equation

4x - 2( y ) = 6

4x - 2( 2x-3 ) = 6 .... replace y with 2x-3; ie plug in y = 2x-3

4x - 2(2x) - 2(-3) = 6

4x - 4x + 6 = 6

0x + 6 = 6

0 + 6 = 6

6 = 6

We get a true statement. The last equation is always true regardless of what we plug in for x, so this is another way to see how we get to infinitely many solutions.

Side note: the system is considered dependent since one equation depends on the other. The system is also consistent since it has at least one solution.

Students are making ornaments and each takes 1/4 of a piece of Bristol board. They go to the cupboard and find 2 1/2 pieces of Bristol board. How many ornaments can they make?

Answers

Answer: 10 ornaments

Step-by-step explanation:

From the question, we are informed that students are making ornaments and each takes 1/4 of a piece of Bristol board. We are further told that they go to the cupboard and find 2 1/2 pieces of Bristol board.

The number of ornaments that they make will be gotten by dividing 2 1/2 by 1/4. This will be:

= 2 1/2 ÷ 1/4

= 5/2 ÷ 1/4

= 5/2 × 4/1

= 10

They can make 10 ornaments

By selling an article for $320, the profit was 20% of the cost price. What was the cost price of the article?

Answers

Answer:

70 percent

Step-by-step explanation:

Lets assume initial cost price (CP) which is 100.

The profit (P) is 320 (320% of 100 is 320)  understood?

Selling Price (SP) is CP +P. So SP must be 420

so basically Now CP increases by 25%. So new cost price (CP1) is 125.

SP remains constant at 420

New profit (P1) is SP - CP1 = 295

P1 as a percentage of SP is (295/420) x 100 = 70%

Answers

X is equal to 7 and y is equal to 63
you get this by equaling the two y= equations to each other so 9x=2x+49 then you would solve algebraically to get x so 7x=49.
X=7
Then you would go back to the two original y= equations and place the value of x into the equation to find the value of y so
Y=9(7)
Y=63 and if you want to check it to make sure its right you can place it into the other y= equation and the values should be the same and in this case they are so the values are correct .

Geraldo has a gold chain that is 34 inches long. He cuts it into 2-inch-long chains. How many gold
chains does Geraldo have now?

Answers

Geraldo has 17 gold chains as calculated by the basic arithmetic operation of division.

Division is an arithmetic operation in which a number is broken down into smaller pieces.

One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division.The other operations are multiplication, addition, and subtraction.In its most basic form, the division of two natural numbers involves, among other things, counting how many times one number appears inside another. This count does not necessarily have to be an integer.The number that is divided is called the dividend, the number that is dividing is called divisor and the quotient is the number that is result of the division.

Now Geraldo has a 34 inch long gold chain. Therefore if he cuts it into 2-inch long pieces then we will divide 34 by 2 and the quotient will give us the number of chains.

∴ 34 ÷ 2 = 17

Hence Geraldo will have 17 chains.

5. Among 70 students , 40 like tea 24 like coffee and 12 like both drinks then find

a. how many like only coffee?
b. how many like neither of the drinks?

Answers

Answer:

12 students like only coffee

12 students like neither of the drinks

Step-by-step explanation:

There are 70 students in total. 40 of them line tea, 24 of them like coffee, and 12 of them like both drinks.

Let's go reasoning step by step.

a.

We have 24 students who like coffee, and we know 12 of them also like tea. The number of students who like only coffee is the difference between those numbers: 24 - 12 =12

12 students like only coffee

b.

With similar reasoning as for part a, 40 students like tea, 12 of which also like coffee, then 40 - 12 = 28 students like only tea.

We have a total of 12 students who like only coffee, 28 students who like only tea, and 12 students who like both. In total there are 12 + 28 + 12 = 52 students who like any or both drinks.

Since there are 70 students in all, we can say 70 - 58 = 12 students don't like coffee nor tea.

12 students like neither of the drinks
