Answer:

If we rent the same car from both companies it would take 8 days

Step-by-step explanation:

Johnson's   50+2x

Martinez     30+4x

a) [tex]10[/tex] additional days are required for both to cost the same.

b) The cost is [tex]70[/tex]$.

At Johan's Rental:

Rent[tex]=(50+2x)[/tex]$

At Martinez Rent:

Rent[tex]=(30+4x)[/tex]$

For both the cost same

[tex]50+2x=30+4x[/tex]

[tex]2x-4x=30-50[/tex]

     [tex]-2x=-20[/tex]

         [tex]x=10[/tex]

[tex]\therefore[/tex] [tex]10[/tex] additional days are required for both to cost the same.

Cost[tex]=(50+2x)[/tex]

       [tex]=50+2\times 10[/tex]

       [tex]=50+20[/tex]

       [tex]=70[/tex]

Answer:

Step-by-step explanation:

a) Here we have:

"In Family A, the youngest child is 7 years younger than the oldest, who is 18"

Let's define:

Y = age of the youngest child.

O = age of the oldest child.

Then we know that:

Y = O - 7

O = 18

Then we can replace the second equation into the first one:

Y = 18 - 7 = 11.

b) Here we have:

"In Family B, the middle child is 5 years older than the youngest child."

Let's define:

Y = age of the youngest child.

M = age of the middle child.

Here we have only one equation:

M = Y + 5.

Answer:

M = Y + 5.

Step-by-step explanation:

f(x) = 2x^2 - 7x + 3

f(0) = 2(0)^2 - 7(0) + 3

= 0 + 0 + 3

= 3

f(x) = 2x^2 - 7x + 3

f(-2) = 2(-2)^2 - 7(-2) + 3

= 8 + 14 + 3

Answer:

area

Step-by-step explanation:

because when you are ordering sod the person that is laying it down needs measurements like 12x13 not 67 yards, that way they can get the most accurate amount

Esma will need to know area if she  needs to know the size of her yard.

Perimeter is a major property of a 2D shape , It is defined as the distance covered around the shape.It is also called the length of a triangle , rectangle and square.

It has major usage in calculation of the fencing that needs to be done , revolution that is being done etc.

It is given in the question that

Esme wants to put new sod on her front lawn.

she needs to know the size of her yard.

As by the meaning of sod , sod is grass that rolls out on the ground, almost like carpet

It will cover the complete area of the lawn and hence to buy it she will be needing to know the area rather than the perimeter.

Answer:

x=63

Step-by-step explanation:

Answer:

x = 9

Step-by-step explanation:

Given

3 - 4x = - 60 + 3x ( subtract 3x from both sides )

3 - 7x = - 60 ( subtract 3 from both sides )

- 7x = - 63 ( divide both sides by - 7 )

x = 9

Answer:

you substitute the variable with its value and the equation makes sense

Step-by-step explanation:

3+y=8

subtract 3 from both sides and you get

y=5

so, if y=5 then 3+y=8 is the same as saying 3+5=8 which is correct

Answer:

That their milkshakes need more caramel or less ice cream.

Step-by-step explanation:

We can see that Ari's numbers for a perfect milkshake gives us a caramel to ice cream ratio of 333 / 555 = 0,6.

But the Freeze Zone uses a caramel to ice cream ratio of 666 / 888 which is equal to 0,75.

Their milkshakes have less caramel and more ice cream than Ari's perfect milkshake so Ari will think that Freeze Zone's milkshakes are not sweet enough.

Solving this equation,

   (4.3 x [tex]10^{-3}[/tex]) (2 x [tex]10^{-2}[/tex])  = 4.3 x [tex]10^{-3}[/tex] x 2 x [tex]10^{-2}[/tex]

Answer:

D

Step-by-step explanation:

The solution is, the value of x is, D) x ≤ -30.

An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.

here, we have,

given that,

x + 20 ≤ -10

now, we have to solve this,

at first we subtract 20 from both sides, we get,

x + 20 - 20  ≤ -10 -20

or, x  ≤ -30

Hence, The solution is, the value of x is, D) x ≤ -30.

The value of  g(x) = 2x² - 4, when g(-2) = 4

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.

Given:

g(x) = 2x² - 4

The above function is a quadratic function.

The solution of when g(-2):

Substituting the value of x = -2

 g(x) = 2x² - 4

g(x) = 2(-2)² - 4

g(x) = 8 - 4

g(x) = 4

Therefore, the value of g(-2) = 4.

Given:

Initial height of tree = [tex]7\dfrac{11}{12}[/tex] foot

He cut [tex]1\dfrac{2}{3}[/tex] off of tree.

To find:

The remaining height of tree after cut.

Solution:

Initial height of tree is

[tex]7\dfrac{11}{12}=\dfrac{7\times 12+11}{12}[/tex]

[tex]7\dfrac{11}{12}=\dfrac{84+11}{12}[/tex]

[tex]7\dfrac{11}{12}=\dfrac{95}{12}[/tex]

He cut [tex]1\dfrac{2}{3}[/tex] off of tree.

[tex]1\dfrac{2}{3}=\dfrac{1\times 3+2}{3}[/tex]

[tex]1\dfrac{2}{3}=\dfrac{3+2}{3}[/tex]

[tex]1\dfrac{2}{3}=\dfrac{5}{3}[/tex]

Now,

Remaining height = Initial height - cut

[tex]=\dfrac{95}{12}-\dfrac{5}{3}[/tex]

[tex]=\dfrac{95-20}{12}[/tex]

[tex]=\dfrac{75}{12}[/tex]

[tex]=\dfrac{25}{4}[/tex]

[tex]=\dfrac{6\times 4+1}{4}[/tex]

[tex]=6\dfrac{1}{4}[/tex]

Therefore, the remaining height of the tree is [tex]6\dfrac{1}{4}[/tex] foot.
