Please help solve for x

Answer:

$69.75

Step-by-step explanation:

$9 x 7 = $63

45 min/60 min = 0.75

$9 x 0.75 = $6.75

$63 + $6.75 = $69.75

Answer:

$69.75

Step-by-step explanation:

$9 x 7 hours = $63

$9 x 3/4 = $6.75

$63 + $6.75 = $69.75

Answer:

The answer would be D

Step-by-step explanation:

Why? because as the temperature increases the amount of lemonade sold increases by 2

This is represented in 2(x) if that makes sense

For every 1-degree increase in high temp of the day, sales decrease by 2 glasses of lemonade. Then the correct option is D.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The function is given below.

f(x) = 2(x – 65) + 12

f(x) = 2x – 130 + 12

f(x) = 2x – 118

For every 1-degree increase in high temp of the day, sales increase by 2 glasses of lemonade. Then the correct option is D.

Step-by-step explanation:

Per our conceptual understanding, when two parallel lines are cut by a transversal line then their corresponding angles are equal.

So, If PQ and RS are two parallel lines and line L1 as shown is the transversal line then the corresponding angles are equal.

Hence, ∠1 = ∠2Or, c0 = 1800 – c02c = 180c = 90°

Therefore, if we get c = 90° then PQ and RS are parallel else PQ and RS are not parallel,

With this understanding, let us now analyse the individual statements.

Step 3: Analyse Statement 1

“b = 2a”

Per conceptual understanding, the sum of all the angles of a triangle is 180.

Hence, a + b + c = 180a + 2a + c = 1803a + c = 180

However, from the above equation, we can get many values of a and c.

Hence, statement 1 is not sufficient to answer the question.

Step 4: Analyse Statement 2

“c = 3a”

a + b + c = 180a + b + 3a = 180b + 4a = 180

However, from the above equation, we can get many values of a and b.

Hence, statement 2 is not sufficient to answer the question.Step 5: Combine Both Statements Together (If Needed)

From statement 1:

3a + c = 180

From statement 2:

c = 3a

Combining both the statements:

3a + 3a = 180.

From the above equation, we can find the value of a. Then we can find c.

Since we could find the answer by combining both the statements, option C is the correct answer.

Answer:

y = -x +2

Step-by-step explanation:

First let's find the slope.

(-1,3) and (4,-2)

3 - -2/ -1 - 4 = 5/-5 = -1

Slope = -1

Now let's use slope intercept form:

y1-y2=m(x1-x2)

Let's plug in our slope for m.

y1-y2= -1 (x1-x2)

And now let's substitute y2 and x2 for one of our points, I'll use (4,-2)

y1+2 = -1(x1- 4)

y= -x + 4 -2

y = -x +2

Step-by-step explanation:

use the pythagorean theorem to figure out what the hypotenuse is

3.5^2+3.5^2=x^2

12.25+12.25=x^2

25=x^2

x=5

now that you know the hypotenuse, you can find the perimeter by adding up all the sides

3.5+3.5+5=12

x > 3

(adding extra characters so its over 20)

Answer:

(a) 19%

(b) 5:6

Step-by-step explanation:

Given: Gh 258,000

salaries Gh 49,020

training Gh 72,000

housing Gh 60,000

entertainment Gh 12,000

exigencies Gh 23,020

(a) Percentage of the income spent on salaries = [tex]\frac{amount of salaries}{total income}[/tex] x 100

                           = [tex]\frac{49020}{258000}[/tex] x 100

                           = 0.19 x 100%

                           = 19%

The percentage of the income spent on salaries is 19%.

(b) Ratio of amount for housing to amount for training = [tex]\frac{amount for housing}{amount for training}[/tex]

                                = [tex]\frac{60000}{72000}[/tex]

                                = [tex]\frac{5}{6}[/tex]

The ratio of the amount for housing to the amount for training is 5:6

Answer:

A) x = -3

Step-by-step explanation:

|3(-3) + 9| = 0

|-9 + 9| = 0

|0| = 0

0 = 0

Answer:

A)x=−3

Step-by-step explanation:

Step 1: Add -6 to both sides.

|3x+9|+6+−6=6+−6

|3x+9|=0

Step 2: Solve Absolute Value.

|3x+9|=0

We know 3x+9=0

3x+9=0(Possibility 1)

3x+9−9=0−9(Subtract 9 from both sides)

3x=−9

3x /3 = −9 /3

(Divide both sides by 3)

x=−3

The value of x that would make the relation a function is x = 3.

Option D is the correct answer.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

{ (-2, -3), (-3, -2), (2, 3), (3, 2), (x, 2) }

A function can not be one-to-many.

A function can be many-to-one and one-to-one

Now,

If x = 2, -3, -2 we get one-to-many.

But if x = 3 we get one-to-one.

Thus,

x = 3.

Answer:

852 students walking to school

Step-by-step explanation:

Lets start with a simple example so you can get it

if 60% of 100 students walk to school that means

60 students walk to school... right??

so lets simplify it more that means you have multiplied 100 (students) by 60%

or [tex]\frac{60}{100}[/tex]  (note: you can say that 60% is equal to [tex]\frac{60}{100}[/tex] )

so the problem told 60% of 1420 students walk to school that means we should

do this:     [tex]1420*\frac{60}{100} = 852[/tex]

Answer:

852 walk to school

Step-by-step explanation:

i got this because i divided the 1420 into 10 which became a 142, multiply by 6 and you get 852

also you could

it is really simple also, all you have to do is multiply the number of student, S times the precent of students who walk, so s times w, which is 60 precent turend into .6 precent so 1420 x .6

Any 3 digit number can be expressed in the form of:

[tex](a*100)+(b*10)+(c*1)[/tex]

Where [tex]a, b, c[/tex] represent any natural number from 0 to 9.

We are told the hundreds number (this means [tex]a*100[/tex] in the expression above) is equal to the value of 40 tens, 40 tens is 400. Then, we know the digit in the tens is greater then 6, this means [tex]b>6[/tex] in the expression above.

So, there are multiple numbers the room number could be, namely:

[tex]400+(b*10)+(c*1)\\[/tex]

where [tex]b[/tex] can be 7, 8, or 9; and [tex]c[/tex] can be  0, 1, 2, 3, 4, 5, 6, 7, 8, or 9. So, there's 30 possible room numbers Lydia may be.
