Answer:

Yes, both have the same value ( 20) when x = 5.

Step-by-step explanation:

We have two functions:

y = 15 + x

y = 4*x

We want to see if these functions have the same value when x = 5.

Then we just need to replace x by 5 in both equations, and see if the values of y are the same

first function:

y = 15 + 5 = 20

second function:

y = 4*5 = 20

So yes, both functions are equal to 20 when x = 5.

Answer:

Yes.

Step-by-step explanation:

4(5)=20

15+5=20

Answer:

15 boys

Step-by-step explanation:

About 0.2of all the students in the fifth grade are boys. If the fifth grade has ​75 students, how many of the students are ​boys?

The number of boys can be calculated as:

0.2 × Number of fifth grade students

Number of fifth grade students = 75 students

Therefore,

The number of boys =

0.2 × 75 students = 15

The number of boys = 15 boys

The answer of expression is 632184, it in fraction is 1264368/2.

The adding of groups is called as Multiplication. When we multiply, the number of things in the group increases.

The combination of numbers, variables and operators is known as Expression

In the given expression multiplication or product is the operator.

213×212×14

When we multiply we get 632184.

Now we have to write 632184 in fractional form.

For this let us multiply numerator and denominator by 2.

So we get 1264368/2

and this can also we can write in mixed number.

We can write this value in fraction as 1264368/2

and we can also write in mixed number 4 632164/5.

Hence the answer as fraction is 1264368/2.

Answer:

Width: 4 meters. Length: 11 meters

Step-by-step explanation:

If you do it correctly, the length should be 3 more greater than 4*2. 4*2= 8 +3= 11. Your perimeter= 30 meters. 11+11 accounting for both long sides of the rectangle= 22. Accounting for both sides of the width, so 4*2=8 + our 22= 30 meters. Yw.

The length of the rectangle​ width 4 meters and length 11 meters.

If you do it correctly,

The length should be 3 more greater than

P=2(l+w)

L= Length

W = Width

4*2. 4*2= 8 +3= 11.

Your perimeter= 30 meters.

11+11 accounting for both long sides of the rectangle= 22.

Accounting for both sides of the width,

So 4*2=8 + our 22= 30 meters.

Therefore we get the length of a rectangle is  11 meters.

Answer:

12 ≤ x

Explanation:

Kids 12 and under, meaning that the age of someone who enters the restaurant has to be less than or equal to 12 to eat free

The inequality which represents the age of the people who do not get the discount is x > 12.

Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.

Given that,

Children 12 and under eat free at a local restaurant.

Let x represents the age of the people.

Since the children who are 12 and under will get the discount, the age of the people who do not get the discount is the people with age greater than 12.

That is the inequality representing this situation is,

x > 12

Hence the required inequality is x > 12.

Answer:

Y-Int = -12

Step-by-step explanation:

First, I would change the equation to slope intercept form:

-3y = 36 + 4x

3y = -36 - 4x

y = -12-4/3x

y = -4/3x - 12

-12 is the y-intercepts to graph the equation-4x - 3y = 36

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The given equation is -4x-3y=36

Now let us convert the given equation to slope intercept form y=mx+b

where m is the slope and b is the y intercept

Isolate the term y

-3y=36+4x

Divide both sides by 3

-y=36/3+4/3x

Multiply both sides by -

y=-12-4/3x

y=-4/3x-12

Slope is -4/3 and y intercept is -12

Hence, -12 is the y-intercepts to graph the equation-4x - 3y = 36
