what is the answer of the problem??????because i got 98.

Answer:

7/5

Step-by-step explanation:

2−x+10−4x=5

2−x+10−4x=5

2+−x+10+−4x=5

(−x+−4x)+(2+10)=5(Combine Like Terms)

−5x+12=5

−5x+12=5

−5x+12−12=5−12

−5x=−7

−5x /−5 = −7 /−5

x= 7 /5

Answer:

a. The T-shirt on discount is $24.30

b. x = 0.9r

c. The regular price of the socks is $15

Step-by-step explanation:

If everything in the mall is at a 10% discount then you must multiply every regular sale by 0.9(90%). To get the regular price of the socks, you must divide by 0.9(10%).

Answer:

1500 kg

Step-by-step explanation:

8 bags = 400 kg

1 bag = 400/8

= 50 kg

30 bags = 30×50

= 1500 kg

Answer:

Step-by-step explanation:

First of all, calculate the weight of 1 bag of sugar first.

400/8=50

So 1 bag of sugar is 50 Kg.

There are 30 bags of sugar so multiply 50 by 30

You will get 1,500Kg for 30 bags of sugar.

Answer:

Maximum daily revenue = $2,249,600

Step-by-step explanation:

If you approach this problem with a trail and error mindset you can quickly calculate that if you take an increase of $6  per ticket or $76 per ticket, then subtract the equivalent loss of visitors which would be 800 * 3 or 2,400 then you get 29,600 visitors. By simply multiplying this number by the cost of the tickets you achive  2,249,600 daily. This could be wrong as I did not use a formula.    

Answer:

15 feets ; 45 feets ; 60 feets ; 75 feets

Step-by-step explanation:

Given that:

Moving at a constant speed ; Distance traveled in 2 seconds = 30 feets

The traveling speed = distance / time

Traveling speed = 30 feets / 2 seconds

Traveling speed = 15 ft/s

Distance traveled = traveling speed * time

Distance traveled after 1 second :

Time = 1 second

15ft/s * 1s = 15 ft

Distance traveled after 3 second :

Time = 3 second

15ft/s * 3s = 45 ft

Distance traveled after 4 second :

Time = 4 second

15ft/s * 4s = 60 ft

Distance traveled after 5 second :

Time = 5 second

15ft/s * 5s = 75 ft

Answer:

We have 250 sixth-grade students are at the school

Step-by-step explanation:

Let the total number of sixth graders be represented as x

Therefore we solve the question nas shown below:

40% of x = 100 sixth grade students that prefer Hip -pop

= 40/100 × x = 100

= 40x /100 = 1000

Cross y

40x = 100 × 100

40x = 10000

x = 10000/40

x = 250 students

Hence, we have 250 sixth-grade students are at the school

Answer:

$13.50

Step-by-step explanation:

Multiply the price by the discount, then subtract that number from the original price.

15.00 x 10% = $1.50

$15.00-$1.50 = $13.50

Answer:

$13.5

Step-by-step explanation:

Discount is 10%

So 15*10/100=$1.5

$15-$1.5=$13.5

Answer:

It will take 18 weeks

Step-by-step explanation:

Here, we are told that she owes a total of $81 which decreases at a rate of $4.50 per week

The number of weeks it will take to finish paying the debt will be the amount owed divided by the payment per week

Mathematically that is 81/4.5 = 18

First, find the converting ratio for kilometers to miles, which is

1km = 1.61 miles.

Then, divide 410 on the side for miles on the ratio.

410km=254.67miles

Therefore, 410 km is equal to 254.67 miles.

Answer:

  see below

Step-by-step explanation:

The given equation is in "slope-intercept" form:

  y = mx + b

where m represents the slope, and b represents the y-intercept.

Your equation has b=2, so one of the points will be on the y-axis at y=2.

__

The slope is m = 3/4. The slope is "rise"/"run" which is the ratio of vertical travel to horizontal travel. The 3/4 means the line will rise 3 units for each 4 units to the right. You can count off the grid squares from (0, 2), the y-intercept, to find another point 4 units right and 3 units up, at (4, 5).

Your line will go through these points.

Answer:

4

Step-by-step explanation:

Given that:

Let the two numbers = a and b

H. C. F of the two numbers = 2

L.C.M of the two numbers = 54

If a = 27 ; b =?

The product of a and b = product of their L. C. M and H. C. F ;

HENCE ;

27 * b = 2 * 54

27b = 108

b = 108/27

b = 4

Hence, second number is 4

Answer:

The best time is 56.81 seconds

Average leg time is 58.3825 seconds

Step-by-step explanation:

Here, we want to start by stating the team’s best time for the race

The team’s best time for the race is the smallest time spent on a lap

From the times given, the best time is 56.81 seconds

Now, we want to calculate the average time

We simply add up all these and divide by count

Mathematically, that will be;

(56.81 + 59.22 + 57.39 + 60.11)/4 = 58.3825 seconds

Answer:

3x + 4y = 16  The rule is you can do any valid operation on both sides of an equation and it will still be equal. Subtract 4y.

3x = -4y + 16  Divide by 3.

x = -4y/3 + 16/3  Answer B.

The solution for the equation 3x + 4y = 16 for x is (16 - 4y)/3 or 16/3 - 4y/3. The correct option is D.

The slope-intercept form of the equation of a line is y = mx + b.

To solve for x, we need to isolate x on one side of the equation. To do this, we can follow these steps:

Move the term containing y to the other side of the equation by subtracting 4y from both sides:

3x + 4y - 4y = 16 - 4y

Simplifying the left-hand side gives:

3x = 16 - 4y

Divide both sides by 3 to isolate x:

3x/3 = (16 - 4y)/3

Simplifying the left-hand side gives:

x = (16 - 4y)/3

So the solution for x is:

x = (16 - 4y)/3

Thus, the correct option is D.

Answer:

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi * r

176 = 2 * pi * r

Divide each side by 2 pi

176 / 2 pi = r

88/ pi = r

We can find the area by

A = pi r^2

A = pi ( 88/ pi) ^2

A =7744/pi

Letting pi = pi button

A =2464.991759 cm^2

A = 2465 cm^2

Letting pi = 3.14

A =2466.242038 cm^2

A = 2466.2 cm^2

Answer:

2463.01 cm²

Step-by-step explanation:

First, find the radius using the circumference formula:

C = 2[tex]\pi[/tex]r

176 = 2[tex]\pi[/tex]r

Divide each side by 2 pi

28 = r

Then, use the circle area formula:

A = [tex]\pi[/tex]r²

A = [tex]\pi[/tex](28²)

A = 2463.01

So, the area of the circle is 2463.01 cm²
