What is the difference of ( 6x -7 y) and (4x+3 y)

1 answer:

6 0

To find the difference between (6x-7y) and (4x+3y) would be by subtracting both the equations. To start, first set up an expression:
(6x-7y)-(4x+3y)

When done, subtract any like terms and add the remaing together:

(6x-4x) +(-7y-3y)

This will result in your answer, 2x-10y

a pattern has 14 triangles to every 18 yellow triangles. what is the ratio of yellow triangles to blue triangles?

9:7
Ratios are always simplified so by dividing both 18 and 14 by 2 you get 9 and seven. Because yellow triangles is stated first the 9 is put before the 7 blue triangles.

I don´t understand this: Lin’s father is paying for a $20 meal. a) He has a 15%-off coupon for the meal. How much is the discoun

Naddika [18.5K]

You'll have to set this up as two separate problems. First, we want to take 15% off the original $20 bill. To do this, you're going to multiply 20 by .15, which gives you $3. So, 15% off $20 is $17.

Now, we want to find 7% of the new bill, so we're going to multiply 17 by .07 to get $1.19, and add it to the $17, making the final bill $18.19. You could also multiply $17 by 1.07 to get your final total without the extra step in the middle, but only do that once you're comfortable with the math.

Which expressions are polynomials?

cupoosta [38]

<em><u>The expressions that are polynomial are:</u></em>

6 + w

$2x^4 - y$

z + 1

<em><u>Solution:</u></em>

A polynomial is an expression with variables and coefficients with the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables

1) 6 + w

Here "w" is a variable, hence it is a polynomial expression

$2)\ 2x^4 - y$
