Answer:

$4x \times 448$

Step-by-step explanation:

A=

$a = (x - 16)$

$b = (3x + 28)$

So you add :

$x \: and3x$

To get

$4x$

Then you do :

$16 \times 28$

To get :

$448$

Answer is :

$4x \times 448$

Denise would like to purchase a computer that costs$2000. Create and solve an inequality in order to determine the least amount

photoshop1234 [79]

The question is incomplete. Here is the complete question:

Denise earns $30 an hour. She wants to purchase a computer that costs $2000. Create and solve an inequality to determine the least amount of hours she must work in order to be able to purchase the computer.

Answer:

$30h\geq 2000\ or\\h\geq67$

Denise has to work at least 67 hours in order to buy a computer that costs $2000.

Step-by-step explanation:

Given:

Hourly earning of Denise is $30.

Let the number of hours Denise works be 'h'.

Now, total earning of Denise can be calculated using the unitary method and is given as:

$Total\ money=\textrm{Hourly earning}\times \textrm{Total hours worked}\\Total\ money=30\times h\\Total\ money=30h$

Now, total money earned by Denise must be at least $2000 in order to purchase a computer. Therefore, the inequality is given as:

$30h\geq 2000\\h\geq \frac{2000}{30}\\h\geq 66.7$

Therefore, Denise has to work at least 67 hours in order to buy a computer that costs $2000.

place the following steps in order to complete the square and solve the quadratic equation, x^2-6x+7=0

MatroZZZ [7]

We have that
x²<span>-6x+7=0
</span>Group terms that contain the same variable
(x²-6x)+7=0
Complete the square Remember to balance the equation
(x²-6x+9-9)+7=0
Rewrite as perfect squares
(x-3)²+7-9=0
(x-3)²-2=0
(x-3)²=2
(x-3)=(+/-)√2
x=(+/-)√2+3

the solutions are
x=√2+3
x=-√2+3

Answer:

D. 32 times; 5/4*40 = 32

Step-by-step explanation:

It is expected the spinner to land on Red 1/5 times.

<u>If the spinner is spun 40 times, then it should land on Red:</u>

1/5*40 = 8 times

<u>And it should not land on red:</u>

(1 - 1/5)*40 = 4/5*40 = 32 times

Correct choice is D

An owner of Honda City car sells his car at a price of RM 7.50,000 with a loss present of 12.5%. Then find the price at which he

Mars2501 [29]

Answer:

Cost = RM 857143

Loss = RM 107143

Step-by-step explanation:

<u>Given:</u>

Selling price SP = RM 750000
Loss% = 12.5
Cost price CP = x

<u>Cost price is found as:</u>

SP = CP - 12.5%
750000 = x - 12.5%
750000= x*(100-12.5)/100
750000= 0.875x
x= 750000/0.875
x≈ RM 857143

<u>Loss is:</u>

RM 857143 - 750000 = RM 107143
