Answer:

Let's solve your system by elimination.

2a + 3c =66 ; 3a + 5c = 105

Multiply the first equation by 5,and multiply the second equation by -3.

5 (2a + 3c = 66)

−3 (3a + 5c = 105)

Becomes:

10a + 15c = 330

−9a − 15c = −315

Add these equations to eliminate c:

a = 15

Now that we've found a let's plug it back in to solve for c.

Write down an original equation:

2a + 3c = 66

Substitute 15 for a in 2a + 3c = 66:

(2)(15) + 3c = 66

3c + 30 = 66 (Simplify both sides of the equation)

3c + 30 −30 = 66 −30 (Add -30 to both sides)

3c = 36

3c3= 363 (Divide both sides by 3)

c = 12

Answer:

a = 15 and c = 12

Step-by-step explanation:

It takes 20 seconds for the cheetah to catch up to the antelope

Speed is the ratio of distance to time taken. It is given by:

Speed = distance / time

Let d represent the distance covered by the cheetah at time t, hence:

30 = d / t

t = d / 30

The antelope is 100 yards away, hence:

25 = (d - 100) / t

t = (d - 100)/25

d/30 = (d - 100)/25

25d = 30d - 3000

d = 600 yards

t = d/30 = 600/30 = 20 seconds

It takes 20 seconds for the cheetah to catch up to the antelope

Step-by-step explanation:

He has widht, heigh and length.

The cubic function is used to represent the length, width or height of a box. The correct option is C.

The cubic function is defined as a function having a degree of three. It is the same as that of cubic polynomials.

A cubic function is defined in mathematics as a function of form f(x)=ax³+bx²+cx+d, where the coefficients a, b, c, and d are complex numbers and the variable x takes real values.

The box has three dimensions that are length, width, and height. The volume of the box will be calculated by the product of the three sides of the box.

There are three dimensions involved in the calculation of the volume of the box. It means that the volume will be a cubic function.

The value of the equation A = ( 8 . 4 ) + ( 2 . 4 ) + 2 = 42

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = ( 8 + 2 ) . 4 + 2   be equation (1)

On simplifying the equation , we get

A = ( 10 ) 4 + 2

A = 40 + 2

A = 42

Substitute the value of A as

A = ( 8 . 4 ) + ( 2 . 4 ) + 2

On simplifying the equation , we get

A = 32 + 8 + 2

A = 40 + 2

A = 42

Hence , the equation is A = ( 8 . 4 ) + ( 2 . 4 ) + 2

-1.25 is less than -1.02 and 1.4.

> -1.25 + 1.02 = -0.23

1.4 is a greater amount because it is a positive number

So, if you put it this way, -1.25 is lesser, -1.02 is the 2nd least, & 1.4 is the greatest.

Which means your overall answer should be -1.25 < -1.02 < 1.4

Answer:

Step-by-step explanation:

If the angle of elevation at point B is 7.4°, then the sun is 90° -7.4° = 82.6° from the vertical. This is the measure of the central angle between the two points. That represents a fraction of a circle that is ...

  82.6°/360° = 413/1800 ≈ 0.229444...(repeating)

The relation between the given distance and the circumference is ...

  0.294444C = 2105 mi

  C = 2105 mi/0.294444 ≈ 9174 mi

The radius of the spherical planet is this divided by 2π:

  r = C/(2π) = 9174 mi/(2π) ≈ 1460 mi

The radius of the planet is about 1460 miles; the circumference is about 9174 miles.

Step-by-step explanation:

the numbers : x, y

x = 5 + 3y

x + y = 33

when using the first equation in the second we get the mentioned equation (it does not matter which of the 2 numbers is x and which is y, it can all be vice versa, as you can see) :

5 + 3y + y = 33

5 + 4y = 33

4y = 28

y = 7

so, when you try the numbers above in the unsimplified equation, you will also find that 7 is the right answer.

the other number is based on my equations (with the reversed names) :

x = 5 + 3y = 5 + 3×7 = 5 + 21 = 26

the smaller number is 7.

the larger number is 26.
