Number 10

Answer:

a = 50

c = 20

Step-by-step explanation:

Let a = adult tickets

Let c = child tickets
Equations:

9a + 5c = 550 ————> (1)

a + c = 70 ————> (2)

Solve for a using second equation

a = 70 - c

Plug in for a using first equation

9(70 - c) + 5c = 550

Solve for c

c = 20

Plug in for c using second equation

a + 20 = 70

a = 50

There is relationship between miles and feet. 1 mile has 5280 feet.

Option A: Ellen's house is 898 feet farther away than Dirk’s. is correct.

Miles and feet both measures distance. The relationship between the two is given by the expression:

1 mile = 5280 feet.

You can use the above given relation to find how many miles are there houses apart.

[tex]1 \: \rm mile = 5280 \: \rm feet.\\\\ 1 \: feet = \dfrac{1}{5280} \: miles\\\\ 6547\: feet = \dfrac{6547}{5280} \: miles \approx 1.24 \: miles[/tex]

Difference between both the distance is 1.41 - 1.24 = 0.17 miles

Converting this to feet:

[tex]1\rm \: mile = 5280 \: feet\\ 0.17 \: mile = 5280 \times 0.17 \approx 898 \: feet[/tex]

Thus, Option A: Ellen's house is 898 feet farther away than Dirk’s. is correct.

The value of the equation 4 over the quantity 7 times the binomial x plus 6 equals x over the quantity x plus 6 is given by A = 4 over 7

The value of A = 4/7

What is an Equation?

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 given by the equation

4 over the quantity 7 times the binomial x

The value is 4 / 7 ( x + 6 )

And ,

x over the quantity x plus 6

The value is x / ( x + 6 )

So , substituting the values in the equation , we get

4 / 7 ( x + 6 ) = x / ( x + 6 )   be equation (1)

On simplifying the equation , we get

The denominators of both the sides of the equation is same or common

And ,

Multiplying by ( x + 6 ) on both sides of the equation , we get

4/7 = x

Therefore , the value of x is 4/7

Hence , The value of the equation 4 over the quantity 7 times the binomial x plus 6 equals x over the quantity x plus 6 is given by A = 4 over 7

The value of A = 4/7

Answer:

The mistake is the -3 exponent was not applied correctly to the coefficients (the 2 and the 4 in the original question) see image.

Step-by-step explanation:

The exponent rules being used here are applying an exponent to ALL the factors in the numerator (top part) and the denominator (bottom part). It is easier to simplify first. Then the -3 exponent goes on all the factors (the x, the y, and the 2) "Fix" negative exponents by pushing those terms across the fraction bar. Finally, 2^3 is 8. Nothing else can be simplified. See image.

[tex]\left( \cfrac{2x^2}{4y^3} \right)^{-3}\implies \left( \cfrac{4y^3}{2x^2} \right)^{3}\implies \left( \cfrac{2y^3}{x^2} \right)^{3}\implies \cfrac{2^{1\cdot 3}y^{3\cdot 3}}{x^{2\cdot 3}}\implies \cfrac{2^3y^9}{x^6}\implies \cfrac{8y^9}{x^6}~\textit{\large\checkmark} \\\\[-0.35em] ~\dotfill\\\\ \left( \cfrac{2x^2}{4y^3} \right)^{-3}\implies \underset{\bigotimes}{\left( \cfrac{2y^3}{4x^2} \right)^{3}}\implies \left( \cfrac{y^3}{2x^2} \right)^{3}\implies \underset{\bigotimes}{\cfrac{y^9}{2x^6}}[/tex]

Answer:

(9,0)

Step-by-step explanation:

Since we know that M is halfway of point A from the origin, to find point M, take half of point A's x-intercept.

Answer:

Step-by-step explanation:

So he has $100 and you want to see how many golf balls he can purchase well we know he spends $75 on the clubs so

 75

-100

--------

  25

John now has 25 dollars left. One ball is $1.50 so we keep adding or multiplying till we finish 25 dollars

1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 = 24

or

  1.50

x    16

----------

    24

he can purchase 16 golf balls

and the reason why it's 16 is that 16 golf balls are equal to 24 dollars and he can't purchase 17 golf balls or else that would be $25.50 which is more money than he has.
