You convert 20% to .20
Then you multiply 1600 by .20 and you get 320. You're not done yet though.
You subtract 320 from 1600$ and you get
1280 is the discounted price.

Answer:

A. $x(x+12) -7(x+12)$

Step-by-step explanation:

Factoring is the process of taking common terms out of an expression such that one can represent the expression as the result of smaller values. When given the following expression:

$x^2 +5x - 84$

First, represent the linear term as the sum of two terms such that each term shares a common factor with the other terms in the expression.

$x^2 +12x - 7x - 84$

Now take out the common factors,

$x(x+12) -7(x+12)$

Thus, the correct option is choice (A).

Evaulate 10^2 + 6 multiplied by 7 + 8

Alinara [238K]

Evaluating $10^2 + 6 \,\,multiplied\,\, by\,\, 7 + 8$ we get 1590

Step-by-step explanation:

We need to evaluate $10^2 + 6 \,\,multiplied\,\, by\,\, 7 + 8$

Solving:

$10^2 + 6 \,\,multiplied\,\, by\,\, 7 + 8\\=(10^2+6)\times(7+8)\\=(100+6)\times(15)\\=106\times15\\=1590$

So, evaluating $10^2 + 6 \,\,multiplied\,\, by\,\, 7 + 8$ we get 1590

If z varies directly with the product of x and y(z=k x y) , then z is said to vary jointly with x and y .

Dafna1 [17]

The value of z varies jointly with w and y.

What is the constant of proportion?

A constant of proportion is illustrated as the ratio which relates two given quantities with each other in the relationship of proportion. Constant of proportion is also called constant variation, rate of change, and constant ratio.

Solving for the value of constant of variation

let k be the constant of proportion

When a quantity varies directly with others, then we have a relation, y = kx

Given relation is z = kxy —-- 1

Also x varies directly with w i.e. x = k'w, where k' is constant of variation for x and w

Using in equation 1, we have,

z = k(k'w)y

z = kk'wy

z = Kwy, where K is constant of variation i.e. K = kk'

It shows that z varies directly with w and y.

Hence, z varies jointly with w and y.

Step-by-step explanation:

if Charles bought the sneakers for 6.30 and wants to re-sell them with 40% more,

first lets see how much is 40% of 6.30

(6.30*40)/100=2.52

he will resell the shoes with

6.30+2.52=8.82
