Solve for X, and show the equation you would use to solve.

Answer:

C, 55c + 70x  ≥ 750

Step-by-step explanation:

He needs a minimum of $750.

The equation 55c + 70x 750 can be used to calculate how many of each he needs detail in order to make at least $750. The right answer is A.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

Given that,

Number of cars = c

Number of SUVs = x

Amount paid for detailed car = $55

Amount paid for detailed SUV = $70

Cost of coolest cellphone = $750

The inequality for the given data will be written as below,

(Amount paid for detailed car × Number of cars) + (Amount paid for detailed SUV × Number of SUV) ≤ Cost of coolest cellphone

55c + 70x ≤ 750

Therefore, the equation 55c + 70x 750 can be used to calculate how many of each he needs detail in order to make at least $750. The right answer is A.

sqaure root of both times each other gives 5

There is an increase in total participants.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

number of boys = 28

Number of girls = 16

Total participants = 28 + 16 = 44

Now, there is decrease in number of boys by 8%

= 28- 8%  x 28

=28- 8/100 x 28

=28 - 0.08*28

=28 -2.24

= 25.76

and, there is 19% increase in number of girls

=16 + 0.19 x 16

=16 + 3.04

=19.04

So, total participants = 25.76 + 19.04

= 44.8

Hence, there is an increase in total participants.

Answer:

20 miles per hour (20 mi/h)

Step-by-step explanation:

100 miles/5 hours = 20 miles/ 1 hour

(simplify the proportion)

Consider the following formula s=d/t, with

s being the speed, d as the distance, and t as the time.

this is because miles per hour is a measurement of speed.

In this case, 100 miles is the distance. 5 hours is the time, and we are solving for s.

s = 100/5, s = 20/1, s = 20 which is 20. So the rate or the speed is 20 miles per hour.

Anything multiplied or divided by 1 will remain the same.

Okay, let's define what a circumference is.

Circumference - The entire outside of a circle, think of it as the "perimeter" of the circle, like how there is a perimeter for a triangle or square.

The equation for finding the circumference is as follows:

[tex]2\pi r[/tex]

r - the radius, or half-way line is a circle.

So, you see the number thats on a half way line in the circle? That is the radius. All you have to do is plug in that number into the equation (for r), and you get the answer.

#3

r = 15

[tex]2\pi (15) = 30\pi \\[/tex]

Now use a calculator and type in 30, then times it by pi (which is this symbol: [tex]\pi[/tex])

Circumference = 94.248

#4

r = 10

[tex]2\pi (10) = 20\pi \\[/tex]

Circumference = 62.832

We can tell that the whole L shaped angle is 90 degrees because it has the little box in the corner. Now, the 90 degree angle is split into two parts with that line coming from the box. Those two parts of the whole 90 degree angle add up to 90 degrees.

90 = 4v + 2 + 9v - 3

Now, let's solve for v. Combine like terms.

90 = 13v - 1

Add 1 to both sides.

91 = 13v

Divide both sides by 13

7 = v

Answer:

a). k = 0.75

b). y = 0.75x

Step-by-step explanation:

a). Graph is showing the relation between number of pages (P) illustrated by Indira and number of days taken (D).

   P ∝ D

   P = kD

   Where 'k' is the proportionality constant.

   k = [tex]\frac{P}{D}[/tex]

  From the graph attached,

  For a point with ordered pair (2, 1.5),

Answer:

x= 9/8 , -15/8

Step-by-step explanation:

Answer:

x = 1.125 , x = 9/8

Step-by-step explanation:

|8x+3| = 12

=> 8x + 3 = 12

=> 8x = 12-3 = 9

=> 8x = 9

=> x = 9/8

As 9/8 is a fraction let's make it a decimal.

9/8 * 125/125 (To make it into a power of ten so that we can convert)

=> 1125 / 1000

=> 1.125

Step-by-step explanation:

4x - 6 + 2x = 18

You are solving for x so obviously you have to have your x variable on one side of the equal sign by itself.

So how do you do that? Combine the same calues together and seperate the rest

4x + 2x = 6x

6x = 18 + 6

6x = 24

x = 3

Practice practice practice. Simple stuff. You got this!

Answer:

A. x = 4

Step-by-step explanation:

To answer this question, we first have to combine like terms:

4x - 6 + 2x = 18

6x - 6 = 18

Now, we take away 6 from the left side and add it to the right side:

6x - 6 = 18

     +6   +6

6x = 24

Then, we isolate the variable:

6x = 24

/6     /6

x = 4

Answer:

$3.6 = cost of a t-shirt

$10 = cost of a  sweatshirt

Step-by-step explanation:

Given:

10 t-shirts and 2 sweatshirts = $56.

5 t-shirts and 3 sweatshirts = $48.

x = cost of a t-shirt

y = cost of a  sweatshirt

Find:

Price

Computation:

10x + 2y = 56.......eq1

5x + 3y = 48........eq2

From 2 x eq2

10x + 6y = 96.........eq3

From eq3 - eq1

4y = 40

y = 10

from eq1

10x + 2(10) = 56

10x + 20 = 56

10x = 36

x = 3.6

$3.6 = cost of a t-shirt

$10 = cost of a  sweatshirt
