Help!!!! 100 POINTS (FIRST CORRECT ANSWER GETS BRAINLIEST)

Answer:

15 percent

Step-by-step explanation: You will substract the new value from the old value.

23-20

Now you will get the difference between them and divide that by the original amount.

3/20

This will equal 0.15 in which you now multiply by 100

Answer: [tex]\frac{17}3}[/tex] or 17:3

Step-by-step explanation:

Since Lydia got 17 out of 20 questions correct, that means she got 3 out of 20 incorrect. To get the ratio of correct (17) to incorrect (3) answers, we can simply divide the two numbers as follows:

[tex]\frac{17}3}[/tex] or 17:3

Since this ratio is already in simplest terms, this is the final answer.

Answer:  Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Number of times the spinner spun = 75

Outcomes     Frequency

A                          20

B                           11

C                           14

D                           30

We need to find the experimental probability of spinning an "A" :

so, Probability of spinning an A is given by

Probability of getting an A is 0.27.

Hence, Option 'c' is correct

Answer:

y = 2x - 5

Step-by-step explanation:

Answer: As x increases, the slope of the graph increases.

Answer:

y=-2/5X-12

Step-by-step explanation:

M=x2-x1/y2-y1

  = -2-(-4)/4-9

  = 2/-5

C was given when u received the point (0, -12)

so C is -12

Answer:

y = -5/2x - 1

Step-by-step explanation:

First, we will figure out the slope. We will use the points (0, -1) and (2, -6). To do this, we look at the y values, -1 and -6, and we look at their rate of change. To get to -6 from -1 we subtract 5, or add -5. Now look at x: 0 and 2. To get from 0 to 2, we add 2. Our slope is [tex]\frac{-5}{2}[/tex].

We can use the point (0, -1) because that's our y-intercept. Your y-intercept is the value of y when x is equal to 0. Now, we put our slope and y-intercept into the slope intercept equation:

y = mx + b: where b is the y-intercept and m is the slope

y = -5/2x - 1 is your answer

Answer:

33% of the marbles were red

Alma was definitely correct to say that the tickets are $14 each.

The total amount in dollars the class have for tickets to the science museum

is $140.

The teacher writes as follows:

Alma says the tickets are $14 each.

Mohammed says that 14 students are going for the trip

The teacher divided 140 by 10. This means the number of student in the class is 10 not 14 as Mohammed enunciated.

The teacher divided the total amount available for the ticket($140) by the number of student in the class(10). Then the quotient ($14) is the amount in dollars which each student will pay for the ticket to the science museum.

Therefore, Alma was definitely correct.

.b- 15 = -12

b = 15 - 12

b = 3

. x - 5 = 7

x = 7 + 5

x = 12

. r + 6 = 11

r = 11 - 6

r = 5

. v/15 = 15

v = 15 × 15

v = 225

Answer:

3. b = 3

5. x = 12

7. r = 5

9. v = -225

Step-by-step explanation:

3. b - 15 = -12  

To get b by itself we have to add 15 to both sides.

b = 15-12

b = 3

5. x-5 = 7

To get x by itself we have to add 5 to both sides.

x = 5+7

x = 12

7. r + 6 = 11

To get r by itself we have to subtract 6 to both sides.

r = 11-6

r = 5

9. [tex]\frac{v}{15}[/tex] = -15

To get v by itself we have to multiply [tex]\frac{v}{15}[/tex] by its opposite reciprocal which is [tex]\frac{15}{1}[/tex]

v = -15(15)

v = -225

Answer:

Marco is 21

Step-by-step explanation:

Let the sister's age = x

Marco's age = 2*x - 5

x + 2x - 5 + 14 = 48            Combine the left side of the equation.

3x + 9 = 48                         Subtract 9 from both sides

3x = 48 - 9

3x = 39                               Divide by 3

x = 39/3

x = 13

So the sister is 13

Marco = 2x - 5 = 2*13 - 5

Marco = 21

The equation to represent the problem is written as

$456.50 = 3.5x + $159

the cost of the labor per hour is $85.

Let x be the cost of the labor per hour.

The technician worked on the computer for 3.5 hours, so the labor cost would be 3.5x.

The total cost, including the labor and parts, was $456.50.

So, we can set up an equation to represent the total cost:

Total cost = Labor cost + Parts cost

$456.50 = 3.5x + $159

Solving for x:

Subtract $159 from both sides:

$456.50 - $159 = 3.5x

$297.50 = 3.5x

Finally, divide both sides by 3.5 to find the value of x:

x = $297.50 / 3.5

x = $85

Therefore, the cost of the labor per hour is $85.

Step-by-step explanation:

-3x + 3y = 27

-x + y = 9

y = x + 9

so the y-intercept is 9 (y value when x =0).

and as point (0, 9)

the x-intercept is the x value when y = 0 :

0 = x + 9

x = -9

and as point (-9, 0)
