Answer:

x = 65

Step-by-step explanation:

Complete question is:

Which is the correct solution?

x = 1.8

x = 2.6

x = 45

x = 65

SOLUTION:

The given equation is : [tex]\frac{x}{5}-2=11[/tex]

Substituting all the values of 'x' one by one

-> For  x = 1.8  : [tex]\frac{1.8}{5}-2=11[/tex]

-1.64≠11

-> For x = 2.6 : [tex]\frac{2.6}{5}-2=11[/tex]

-1.48≠11

-> For x = 45 : [tex]\frac{45}{5}-2=11[/tex]

7≠11

-> For x = 65 : [tex]\frac{65}{5}-2=11[/tex]

11=11

Therefore, by substituting x in every equation, x = 65

Answer:

Substitute 7 for a.

Simplify the equation after substituting the value for a.

Verify that a = 7 is correct when the result is a true statement.

Step-by-step explanation:

Here, the given equation is,,

And, after solving it the result is,

a = 7

We can check whether a result is the solution of an equation by substituting the result in the given equation.

If we get a true statement, then the result is the solution of the equation.

Thus, for verifying the solution, steps are as follow,

Step 1 : Substitute 7 ,

-9(7-5) = -18

Step 2 : Simplify the equation after substituting the value of a  

-9(2) = -18    

Step 3 : Verify that a = 7 is correct when the result is a true statement.

-18 = -18      

Answer:

The total distance is  [tex]d_T = 6250 \ m[/tex]

Step-by-step explanation:

From the question we are told that

     The distance from bailey start point to her friends house is  [tex]d = 3 \ km = 3*1000 = 3000 \ m[/tex]

       The distance covered going to and from the park is [tex]d_2 = 250 m[/tex]

The total distance covered is mathematically evaluated as

         [tex]d_T = (2 * d_1) + d_2[/tex]

Substituting values

          [tex]d_T = (2 * 3000) + 250[/tex]

          [tex]d_T = 6250 \ m[/tex]

Answer: A degree

Step-by-step explanation:

Answer:

I also think it is a degree like the other guy

Step-by-step explanation:

Degree of length=1

Degree of width=1

Degree of height=3

Degree of volume=5

The [SUM] of the degree of each factor is the degree of the product

Why does this make sense Answer is C

Since a linear function has a degree of 1, hence the degree of the length, width and height is 1. The degree of the volume is 3

The degree of an equation is the power of the leading variable.

Given the following measures

length = 4x - 1

width = x

height = x -3

Since a linear function has a degree of 1, hence the degree of the length, width and height is 1. The degree of the volume is 3

Answer:

x = -3

Step-by-step explanation:

In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 4 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.

4 ( 2x - 1 ) = 3x - 19

→ Expand the brackets

8x - 4 = 3x - 19

→ Minus 3x from both sides to isolate -19 and bring all the x coefficients to one side

5x - 4 = -19

→ Add -4 to both sides to isolate 5x

5x = -15

→ Divide both sides by 5 to isolate x and therefore find the value of x

x = -3

→ We can substitute x = -3 back into 4 ( 2x - 1 ) = 3x - 19 to see if we have the correct solution, if we end with the same number on both sides then  x = -3 is correct.

4 ( 2x - 1 ) = 3x - 19

8x - 4 = 3x - 19

( 8 × -3 ) - 4 = ( 3 × -3 ) - 19

-24 - 4 = - 9 - 19

-28 = -28

So x = -3 is correct

Answer:

10 hours

Step-by-step explanation:

We can actually solve this problem simply as if it were an equation instead of an inequality. We have:

15 + 8h ≤ 95

Subtract 15 from both sides:

8h ≤ 95 - 15

8h ≤ 80

Divide by 8 from both sides:

h ≤ 80/8

h ≤ 10

So, the number of hours cannot exceed 10, which means the maximum number of hours Susie can rent is 10 hours.

Answer:

34 cm; 48 cm^2

Step-by-step explanation:

5+5+12+12=10+24=34

12(4)=48

The equation to find the sum of interior angles of a n-sided polygon is:

(n - 2) * 180

So, we don't know what n is but we can make it look like this:

(n - 2) * 180 = 8,280

Solve for n.

(n - 2) * 180 = 8,280

~Divide 180 to both sides

(n - 2) * 180/180 = 8,280/180

~Simplify

n - 2 = 46

~Add 2 to both sides

n - 2 + 2 = 46 + 2

~Simplify

n = 48

Therefore, the polygon has 48 sides.

Best of Luck!

Answer:

-The volume of a cylinder can be either:

In terms of pi: [tex]54\pi[/tex]

             or

Using 3.14 for pi: [tex]169.646[/tex] [tex]in^3[/tex]

Step-by-step explanation:

Use the formula for the volume of a cylinder and use the given radius and height for the formula:

[tex]V = \pi r^2 h[/tex]

[tex]V = \pi 3^26[/tex]

Then, solve the formula:

[tex]V = \pi \times 3^2 \times 6[/tex]

[tex]V = \pi \times 9 \times 6[/tex]

[tex]V = \pi \times 54[/tex]

[tex]V = 54\pi \approx 169.646[/tex]

-So, the answers would be:

In terms of pi: [tex]54\pi[/tex]

You can use the sine rule

a / sinA = b / sinB

Substitute the values in:

15 / sin112 = b / sin33

Multiply both sides by sin(33) to get b by itself

b = (15 / sin112) x sin33

Calculate this to get your answer of:

BC = 8.8 cm

2.

You can also use the sine rule here

sinA / a = sinB / b

Sub your values in:

sin84 / 32.4 = sin(y) / 21

Multiply both sides by 21 to isolate sin(y)

(sin84 / 32.4) x 21 = sin(y)

Calculate sin(y)

sin(y) = 0.6445975248

You now need to sin-1 this value to get u:

y = 40.13550596

To 1d.p, y = 40.1 degrees

-13x - 13x = 13 - 12

-29x = 1

x = [tex] \frac{-29}{1} [/tex]

SI = P × R × T

SI = 1000 × 6/100 × 2 = $120

Answer:

see below

Step-by-step explanation:

A: radius of 12 ft

    Changing to meter

 12 ft * .305 m/ ft =3.66 meter

The radius is 3.66 meters

The diameter is twice the radius = 2*3.66 =7.32 meters

The circumference is

C = pi*d = 3.14 * 7.32 =22.9848 = 22.98 meters

B diameter is 7.5 meters

Pool B has a bigger diameter

C = pi * d = 3.14 * 7.5m = 23.55 meters

The difference is .57 meters

Answer:

7.32

B

Larger/greater

0.57

Step-by-step explanation:

Diameter = 2 × radius

= 2 × 12 = 24 feet

24 × 0.305 = 7.32 meters

7.5 > 7.32

So the diameter of pool B is greater

Difference in circumferences:

(3.14 × 7.5) - (3.14 × 7.32)

23.55 - 22.98

0.57 meters
