The number of members going to the tournament is 9(optionC)

Word problem are mathematical problems written and words or sentence. To solve this type of problem we need to interpret the problem into mathematical equation.

Represent the number of members of the club by x and the cost per person be y. The total cost for the trip is $210

therefore 210/x = y equation 1

When 3 students join, the cost per person drops by $5.83

210/(x+3 )= y - 5.83

y = 210/(x+3 )+5.83

210/x = 210/(x+3) + 5.83

multiply all terms by x(x+3)

210(x+3) = 210x + 5.83(x²+9)

210x +630 = 210x + 5.83x²+52.47

630-52.47 = 5.83x²

577.53 = 5.83x²

x²= 577.53/5.83

x² = 99.06

x =✓99.06

x = ± 9.95

since 0.95 is not Up to a person and number of persons is a specific value, then the number of members going for the tournament is 9

Answer:

A

Step-by-step explanation:

The y-intercept is where the line meets the y axis

To do this x has to =0

Your table tells you that when x=0 y=6

this means that 6 is the y intercept

The answer is A

Answer:

the first one

Step-by-step explanation:

slope formula: y2-y1/x2-x1

12-6/3-0

slope=2

from the table, you know the y-intercept is 6

Answer:

Step-by-step explanation:

(a^2 - 5ab) - (7 - 3ab) + (2ab - a^2) = -7

a^2 - 5ab -7 +3ab + 2ab -a^2 = -7 [combine like terms]

a^2 - a^2 = 0

-5ab + 3ab + 2ab = 0

-7 = -7

Answer:

Step-by-step explanation:

you can bring -(7-3ab) to the other side of the equation . then you will have this : (a^2 - 5ab) + (2ab - a^2) = -7 + (7 - 3ab)

now look at this part : -7 + (7 - 3ab) (because adding is a associative procedure) you can get rid of -7 and 7 . then you will have only -3ab

so now this would look like this :  (a^2 - 5ab) + (2ab - a^2) = -3ab

now take a look at the left of the equation : just like the last part we can simplify a^2 and - a^2 . and -5ab + 2ab would result in -3ab

because if you subtract -5ab from a^2 and subtract a^2 from 2ab ... then add then to each other would give you the same result

at the end you will have -3ab = -3ab which is a true conclusion.

3 - 7 = -4

Why?

7 is a bigger number than 3 which makes the answer a negative number.

-9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9

that is a number line and if you start from 3 and go back 7 spaces it would be -4.

In conclusion,

-4 is the absolute value of 3 - 7.

Step-by-step explanation:

b

Answer/Step-by-step explanation  (ac > b² or b² < ac. )

A/c to question, we have to show:-

b² >ac in A.P ........ (1)

b² = ac in G.P .....(2)

b² < ac in H.P. ..... (3)

b = a+c/2 (A.P)

b = √ac ( G.P)

b = 2ac/a+c (H.P)

In A.P :

b² > ac = b² - ac

= (a+c/2)² - ac

= (a²+2ac+c²/4) - ac  = a² + 2ac + c² - 4ac / 4

= a² - 2ac + c² / 4  = ( a - c ) ² / 4 > 0  Hence, b²>ac

In G.P:-

b = √ac

Hence, b² = ac

In H.P :-  b² < ac = ac > b²  = ac - b²  = ac - ( 2ac / a+c)

= ac(a+c) - 2ac / a+c

= a²c + ac² - 2ac / a+c

= ac(2ac - 2) / a+c > 0

Hence, ac > b² or b² < ac.

Answer:

x = 2, y = 6

Step-by-step explanation:

Hi there!

The equation for the cost of baskets of tomatoes can be represented as

3x+5y = 36

The number of baskets can be represented as

x + y = 8

I will be using the substitution method for this question.

First, we have to solve for a variable. X will be easiest in this case.

Multiply the bottom equation by -3 to cancel out 3x and -3x.

Your equation will become [tex]-3x - 3y = -24[/tex]

After the x values are cancelled out, add the values from the top equation into the values of the bottom equation.

this becomes [tex]2y = 12[/tex], or y = 6.

Now that we know the y-value, plug it in either original equation to find x.

x = 2

Answer:

48

Step-by-step explanation:

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

81×61=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

8×61×1=481

Since 48 divided by 1 equals 48 then,

481=48

Therefore:

81÷16=48
