What is 3х – 18y = 4

Answer:

They are different because a positive plus a negitive is a negitive while a positive plus a positive is a positive

4+(-4)=0     4+4=8

Answer: 1/4 times 5

Step-by-step explanation: gtg sorry don’t have time

Answer:

x = 4

Step-by-step explanation:

5x -7 + 2x = 4x + 5

Combine like terms

5x + 2x -7 = 4x + 5

7x - 7 = 4x + 5

Combine like terms again

-4x + 7x - 7 = 4x - 4x + 5

3x - 7 = 5

3x = 5 + 7

3x = 12

Divide by 3 both sides

3x/3 = 12/3

x = 4

Step-by-step explanation:

Step 1: Define

[tex]\displaystyle \frac{a}{-7} - 7 = 5[/tex]

Step 2: Solve for a

Step 3: Check

Plug in a into the original equation to verify it's a solution.

Here we see that 5 does indeed equal 5.

∴ a = -84 is the solution to the equation.

Answer: 30 player on the team

Step-by-step explanation:

If 9 players = 30% of the team then 3 = 10% of the team. With this information you can multiply 10 x 10 to get 100(%) and then multiply 3 x 10 to get 30(players). This may not be how you are supposed to solve this problem but oh well.

Answer:

45.00 is what she has left

Step-by-step explanation:

Anna has $275.5 left after buying computer.

A percentage is a minimum number or ratio that is measured by a fraction of 100.

Given that Amount saved by Anna each month = $30

Time period = 2.75 years.

1 year = 12 months

2.75 years =  2.75 years x 12 = 33 months

The Amount saved in 33 months = 33 x 30 = $990

She spent 75% of her savings.

Amount spent = 75% of 990

Amount spent = 75% x 990

Amount spent = $742.5

Amount left = Savings - Amount spent

Amount left = 990- 742.5= $275.5

Hecne, Anna has $275.5 left after buying computer.

Answer:

The correct answer is Option 1: multiplication

Step-by-step explanation:

Given equation is:

[tex]20 = \frac{w}{6}[/tex]

Given equation is a linear equation with one variable w. In order to solve the linear equations in one variable, properties of equality are used.

Solving for w means that w has to be isolated on one side of the equation i.e. w should be without a multiple or denominator.

The equation will be multiplied by 6 to remove the denominator in w/6

[tex]20*6 = \frac{w}{6} *6\\w = 120[/tex]

Hence,

The correct answer is Option 1: multiplication

Answer:

r = $105.6

Step-by-step explanation:

Given,

Amount paid by Trevor for 4 nights = $528

Rate per day = r

Now,

We know that a 4-night stay in the hotel means 5 days to stay at MGM Grand.

Now,

Amount paid = Number of days x Rate per day

$528 = 5 r

[tex]r = \frac{528}{5}[/tex]

r = $105.6

Hence, Trevor pays $105.6 to stay at the MGM Grand Hotel in Las Vegas for four nights.

Answer: 3x-8

Step-by-step explanation:

The algebraic factor of the given quadratic equation 9x² - 18x + 8 is 3x - 4 thus option (A) is correct.

An algebraic factor is the multiplication of two algebraic terms.

If we divide an algebraic factor by a factor that is available inside then the remainder after the division will be zero.

As per the given quadratic equation,

9x² - 18x + 8

⇒ 9x² - 12x - 6x + 8

⇒ 3x(3x - 4) - 2(3x - 4)

⇒(3x - 4)(3x - 2)

Hence "The algebraic factor of the given quadratic equation 9x² - 18x + 8 is 3x - 4".

Answer:

If a = 3

a -7 = -4

Step-by-step explanation:

Here, we want to find the value of a -7 given that a = 3

To find this value, we are going to make a substitution

We simply substitute 3 for the value of a

we have this as;

3 -7 = -4
