Answer: 2:3

Step-by-step explanation:

12:18 is like a fraction so you can divide it down on each side to make it simple.

12 and 18 can both be dived by 6 at most

I need help! The 20% off sale is a better deal than the $200 rebate or $150 coupon for the $1,500 dining room set. Explain why t

11111nata11111 [884]

Answer:

See explanation

Step-by-step explanation:

The 20% off sale is a better deal because 20% off of $1500 will cost $1200. (See work).

However, the 200 or 150 dollars off will cost $1300-1350. Thus, the better deal for the dining room set is to use the 20% off.

If their budget is $1250, they will be $50 under budget because they would be paying $1200 for the set.

Work:

1500 x 20%

1500 x 0.20 = 300

1500-300= $1200

1500-150= 1350

1500-200= 1300

Drag each label to the correct location on the table. Each label can be used more than once, but not all labels will be used.Sim

Aleonysh [2.5K]

Okay, here we have this:

Let's solve the table polynomial by polynomial:

Polynomial 1:

We will first find its simplified form:

$\begin{gathered} (3x-\frac{1}{4})(4x+8) \\ =3x\cdot\: 4x+3x\cdot\: 8+\mleft(-\frac{1}{4}\mright)\cdot\: 4x+\mleft(-\frac{1}{4}\mright)\cdot\: 8 \\ =12x^2+24x-x-2 \\ =12x^2+23x-2 \end{gathered}$

Name by degree of the polynomial: quadratic.

Polynomial 2:

Let's simplify it:

$\begin{gathered} \mleft(5x^2+7x\mright)-\frac{1}{2}\mleft(10x^2-4\mright) \\ =5x^2+7x-5x^2+2 \\ =7x+2 \end{gathered}$

Name by number of terms: Binomial

Polynomial 3:

Name by degree of the polynomial: constant

Name by number of terms: Monomial

What number is one thousand less than one million?

zhuklara [117]

Answer:

<u>999,000</u>

Step-by-step explanation:

<u>We need to find the number that is one thousand (1,000) </u><u>less than</u><u> one million (1,000,000).</u>

less than clearly refers to subtraction
So, we have to subtract 1,000 from 1,000,000
1,000,000 - 1,000
<u>999,000</u>

Complete this proof.

Alja [10]

Answer:

1) distributive property

2) subtraction property of equality

3) division property of equality

Step-by-step explanation:

Given : If $\frac{1}{2}(8x+14)=39$ , then x=8

To complete the proof :

Solution :

Following are the complete steps or proof of solving the given expression,

$\frac{1}{2}(8x+14)=39$ is given

$4x + 7 = 39$ - distributive property

$4x = 32$ - subtraction property of equality

$x = 8$ - division property of equality

Help I do not understand this

marshall27 [118]

Answer:

sin(30)° = $\frac{10}{x}$

Step-by-step explanation:

By applying sine rule in the given triangle,

sin(30)° = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

sin(30)° = $\frac{10}{x}$

$\frac{1}{2}= \frac{10}{x}$

x = 2 × 10

x = 20

Therefore, answer will be sin(30)° = $\frac{10}{x}$ .
