Answer:

3

Step-by-step explanation:

7 plus three is 10, adding -10 to that equals zero.

The value of x would result in the numerical value of zero in the expression 7+x+(−10) is 3.

Based on the information given, we simply have to find the value of x. Therefore, the value of x from the equation will be:

7 + x + (-10) = 0

Collect like terms

x = 10 - 7

x = 3

Therefore, the value of x would result in the numerical value of zero in the expression 7+x+(−10) will be 3.

Answer:

The selling price of the house is $144,681

Step-by-step explanation:

The computation of the selling price of the house is shown below:

Let us assume the selling price be x

So, the commission would be 0.06x

Now the danny would received

= x - 0.06x

= 0.94x

And, the amount received is $136,000

So equate this value

Like this

0.94x = $136,000

x = [tex]\frac{\$134,000}{0.94}[/tex]

= $144,681

Hence, the selling price of the house is $144,681

Answer:

7 meters

Step-by-step explanation:

Now write an equation that represents the situation. You want to find the change in the dolphin's depth, so subtract its beginning depth from its final depth.

The change in the dolphin's depth is negative 7 meters.

Subtraction of two or more numbers or algebraic expressions is the method of taking away a certain value from a number. This operation is also called difference of numbers.

Subtraction is one of the basic operations in mathematics along with division, multiplication and addition.

Initial depth that Dolphin was swimming = 28 meters

Then the Dolphin changed it's depth to avoid predator.

Final depth that Dolphin was swimming = 21 meters

Change in depth = Final depth - Initial depth

                            = 21 - 28

                            = -7 meters

This implies that depth of the Dolphin decreases with -7 meters.

Hence the change in the Dolphin's depth is -7 meters if the initial depth was 28 meters and final depth was 21 meters.

Answer:

x = -72/17

Step-by-step explanation:

(2/3)*x+(1/2)*x+(1/4)*x+6 = 0

17/12*x+6 = 0 // - 6

17/12*x = -6 // : 17/12

x = -6/17/12

Answer:

y = 4/5x

Step-by-step explanation:

We know it's not y = x - 2 because if you plug x into the equation, it works for the first one, but not the second one. Ex: 10 - 2 = 8 but 5 - 2 = 3 not 4.

We also know that it can't be y = -5/4x because if you plug x into that equation, it does not equal y.

y = 4/5x because when you plug x into the equation it works.

TLDR basically you just plug x into the equations.

Answer:

students 150

adult 550

Step-by-step explanation:

x + y = 700

5x + 2y = 3050

x = 700 - y

5(700 - y) + 2y = 3050

3500 - 5y + 2y = 3050

-3y + 3500 = 3050

-3y = 3050 - 3500

-3y = -450

y = -450 / -3

y = 150

x = 700 - y

x = 700 - 150

x = 550

Answer:

x = 3, x = 4

Step-by-step explanation:

Given

[tex]\frac{24}{x}[/tex] = 14 - 2x ( multiply through by x , x ≠ 0 )

24 = 14x - 2x² ( subtract 14x - 2x² from both sides )

2x² - 14x + 24 = 0 ( divide through by 2 )

x² - 7x + 12 = 0 ← in standard form

(x - 3)(x - 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x - 4 = 0 ⇒ x = 4

Answer:

Step-by-step explanation:

the answer is 25 not 5

The numeric value of x will be 25 for the given line segment.

A line section that can connect two places is referred to as a segment.

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

Given the line segment AC

AC = AB + BC

Given,

AB = 2x + 10, BC = x, and AC = 5x,

So,

5x = 2x + 10 + x

5x = 3x + 10

2x = 10

x = 5

So,

AC = 5x

AC = 5(5) = 25 units.

Hence, The numeric value of x will be 25 for the given line segment.

Answer: C=250S+4500

C=250(17) + 4500    

C=4250+4500

C=8750

Step-by-step explanation:

As an equation, 250 would be the slope because it is multiplying by the ton and 4500 is the y intercept. If you substitute in 17 for S, then multiply 17 by 250, you get 4250 then add the 4500 and you get 8750 so if S=17, C=8750

The cost of transporting 17 tons of sugar is $8750.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

The given information can be related as,

C = 250S + 4500.

Now, when tons of sugar is 17 we'll simply replace S with 17.

∴ C = 250(17) + 4500.

C = 4250 + 4500.

C = 8750.
