Identify in the given expressions, terms which are not constants. Give their numerical coefficients.
(i) 5x – 3
(ii) 11 – 2y2
(iii) 2x – 1​

Answers

Given:

The expression are

(i) [tex]5x-3[/tex]

(ii) [tex]11-2y^2[/tex]

(iii) [tex]2x-1[/tex]

To find:

The terms which are not constants and their numerical coefficients.

Solution:

Constants: The terms which are free from variables.

Numerical coefficient: Number multiplied with a variable.

(i) [tex]5x-3[/tex]

Constant = -3

Term which is not constant = 5x

Numerical coefficient = 5

(ii) [tex]11-2y^2[/tex]

Constant = 11

Term which is not constant = [tex]-2y^2[/tex]

Numerical coefficient = -2

(iii) [tex]2x-1[/tex]

Constant = -1

Term which is not constant = 2x

Numerical coefficient = 2

Therefore, the terms which are not constants are  [tex]5x,-2y^2,2x[/tex]  respectively and their numerical coefficients are 5, -2, 2 respectively.

2.4= -5y + 14.9. Solve for y​

Answers


2.4=-5y+14.9

We move all terms to the left:

2.4-(-5y+14.9)=0

We get rid of parentheses

5y-14.9+2.4=0

We add all the numbers together, and all the variables

5y-12.5=0

We move all terms containing y to the left, all other terms to the right

5y=12.5

y=12.5/5

y=2+2.5/5

Y=2.5

Which is a better deal on a $10 item:

50% off or 10% off and then another 40% off? Explain your answer.

Answers

50% off. You only have to pay $5. If you do 10% off one time you have to pay $9 and then the next time you get 40% off, you’d have to pay $6.

Unless I completely misunderstood, 50% should be better. If it’s 40% off + 10% then it will be 50% and therefore both of them are equal deals and both good.

The length of a rectangle is 9” greater than the width. The area is 36”2. Find the dimensions

Answers

Answer:

Step-by-step explanation:

L = W+9

area = LW = 36

(W+9)W = 36

W²+9W-36 = 0

W = -12, 3

-12 is an extraneous solution, so W = 3 inches

L = W+9 = 12 inches

Choose 3 values that would make this inequality true. 7n ≤ 21

Answers

Answer:

A couple could be 2, 1, or even a decimal 1.3 as an example.

Step-by-step explanation:

Divide both sides by 7:

7n/7 < 21/7

n < 3

Any value of n less than 3 will make the inequality true, so just pick three values (numbers) for n that are less than 3, such as n = 2.
