Step-by-step explanation:

Givens

Let the first number = x

Let the second number = 2x

Let the third number = x + 100

Total = 468

==============

Solution

x + 2x + x + 100 = 468                    Combine the xs

4x + 100 = 468                                Subtract 100 from  both sides

4x = 468 - 100

4x = 368                                          Divide by 4

x = 368/4

x = 92

===============

Answer

First number =                     92

Second num = 2 * 92=       184

Third number = 92 + 100= 192

Total                                    468

Answer:

It cant be further factorise...you may have missed a value.

10 and x square have nothing in common, nor is there any mid number for mid-term breaking, nor any two square numbers to apply identities. If yu can reveiw he question...which I think might be 100-x^2....the answer will be

(10-x)(10+x)

Answer:

$6,583.5

Step-by-step explanation:

Amanda's monthly salary increased by 4.5%. You can get the percentage by getting the increased amount in salary and dividing it by the previous salary of Amanda.

In order to get the new salary of Mary, you have to multiply the same percentage, 4.5%, to Mary's previous salary, $6,300. This will give you the amount that will be added to her new salary.

Mary's new salary is $6,583.5

Answer:

1

Step-by-step explanation:

Any thing to the power 0 will always be 1

x⁰=1

(3^-1=1/3)

(4^-1=1/4)

(5^-1=1/5)

1/3+1/4+1/5=47/60

(47/60)^0=1 (as any thing to the power 0 will always be 1 )

Hope this helps you.

Answer:

$74,750

Step-by-step explanation:

Given that,

The cost of a computer = $65,000 + value added tax at 15%

We need to find the amount the computer actually cost the customer.

Total cost = Cost of computer + VAT at 15%

[tex]=65000+65000\times \dfrac{15}{100}\\\\=\$74,750[/tex]

So, the computer actually cost the customer is $74,750.

The answer and most correct out of the options given is answer "A."

Step-by-step explanation:

Took the test, the person above is right I can confirm. I know a lot of people want confirmation for these answers.

The equation that represents Jayla's current account balance with the initial amount is c=1.07b.

Compounding is a process where the interest is credited to the initial amount and interest, on the whole, is charged again. and this continues for t period of time.

It is given by the formula,

[tex]A = P(1+\dfrac{r}{100})^t[/tex]

where, A is the value after t period of time, and,

r is the rate of interest.

Given to us

Jayla's bank account increased by 7% this year.

The amount that Jayla started with is b,

The amount that Jayla has now is c.

We know the general equation for compound interest is given as,

[tex]A = P(1+\dfrac{r}{100})^t[/tex]

Substituting the values we will get,

[tex]c=b(1 + \dfrac{7\%}{100})^1\\c = b(1.07)[/tex]

Hence, the equation that represents Jayla's current account balance with the initial amount is c=1.07b.

Answer:

5.79

Step-by-step explanation:

I think I'm not very sure tho

It's 7.723, not 5.79.

If you get your bodmas correctly, you should get 7.723.

Solution:

Do "((-4.6) - 1.9) first, which is -6.5 basically.

After that it is (-2.78) x (-2.8), which is 7.784.

After that do (2.2 - 1.8) ÷ ((-4.6) - 1.9), which is -0.061

After that 7.784 + -0.061, which makes it 7.723.

Given:

The function is

[tex]A(x)=(3x-3)(3x+2)[/tex]

To find:

The simplified form of A(x) and value of A(x) at x=1.

Solution:

We have,

[tex]A(x)=(3x-3)(3x+2)[/tex]

[tex]A(x)=(3x)(3x)+(3x)(2)+(-3)(3x)+(-3)(2)[/tex]

[tex]A(x)=9x^2+6x-9x-6[/tex]

[tex]A(x)=9x^2-3x-6[/tex]

Putting x=1, we get

[tex]A(1)=9(1)^2-3(1)-6[/tex]

[tex]A(1)=9-3-6[/tex]

[tex]A(1)=9-9[/tex]

[tex]A(1)=0[/tex]

Therefore, the simplified form of A(x) is [tex]A(x)=9x^2-3x-6[/tex] and the value of A(x) at x=1 in 0.

⇒x2−25x=−23 (Shifting the constant term on RHS)

⇒x2−2(45)x+(45)2=(45)2−23 (Adding (21Coeff.ofx)2 onboth sides)

Answer:

Honestly im not sure

Step-by-step explanation:

5.2°C = (273 + 5.2)k = 278.2k

Change in temperature = 368k -278.2= 89.8k  

q (heat energy) = MCp∆T

When Cp of water =1046J

q = 7.59 g × 1046J × 89.8k

= 712, 934.772Jgk-1 = 713kJgk

When Cp of water =250cal

q = 7.59 g × 250 × 89.8k = 170kCalk

Answer:

x = 1.636364

x = 1.64 (simplified)

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

0.7x=1.8−0.4x

0.7x=1.8+−0.4x

0.7x=−0.4x+1.8

Step 2: Add 0.4x to both sides.

0.7x+0.4x=−0.4x+1.8+0.4x

1.1x=1.8

Step 3: Divide both sides by 1.1.

1.1x/1.1=1.8/1.1

x=1.636364

x = 1.64 (simplified)

Answer:

x = 1.636364

Explanation:

0.7x = 1.8 − 0.4x

0.7x = 1.8 − 0.4x

0.7x = 1.8 + −0.4x

0.7x = −0.4x + 1.8

0.7x + 0.4x = −0.4x + 1.8 + 0.4x

1.1x = 1.8

Divide both sides by 1.1

1.1x / 1.1 = 1.8 / 1.1
