Which equation represents this statement?

5 times the sum of 7 and a number is 40.

5(n+7)=40

5 + 7n = 40

5⋅7+n=40

5n + 7 = 40

Answers

Answer 1

Answer:

5(n+7)=40

Step-by-step explanation:

It's 5(n+7)=40 because 5 + 7n = 40 and 5n + 7 = 40 is addition not multiplication, and 5⋅7+n=40 is saying 5 times seven plus a number is 40, therefore 5(n+7)=40 is the correct answer because the parenthesis in (n+7) seperates it from 5 so that you have to get the sum of (n+7) before you can multiply it by 5.  

Answer 2

The required equation for the given case is 5(n + 7) = 40.

What is a Linear equation?

A linear equation is a equation that has degree as one.

To find the solution of n unknown quantities n number of equations with n number of variables are required.

The given word problem can be solved as follows,

Suppose the unknown number be n.

Then, 5 times the sum of the number and 7 can be written as an expression as,

5(n + 7)

Now, as per the question the following equation can be written,

5(n + 7) = 40

Hence, the equation for the given word problem is 5(n + 7) = 40.

Answer:

Coordinates or points would be  (0,2), (1,2.6) (2,3.2) (3,3.8)

Step-by-step explanation:

Formula

w(x) = 3/5x +2 in each coordinate I have a x so for example 3.

I would rewrite this as 3/5(3) + 2

w(x) = 3/5x +2

w(3) = 3/5(3) + 2

Answers

Answer:

x = 5

Step-by-step explanation:

Question:To find the value of x

Given Equation:3x - 12 = 3

Solution:

=> 3x - 12 = 3

[On putting the like terms on one side of the equation]

=> 3x = 3 + 12

[On adding like terms]

=> 3x = 15

[Dividing both sides with 3]

[tex] = > \frac{3x}{3} = \frac{15}{3} [/tex]

[On Simplification]

=> x = 5 (Ans)

[tex]\sf 3x - 12 = 3[/tex]

[tex]\sf \longmapsto3x = 3 + 12[/tex]

[tex]\sf \longmapsto3x = 15[/tex]

[tex]\sf \longmapsto \: x = \frac{15}{3} [/tex]

A barrel of oil was filled at a constant rate of 7.9 gal/min. The barrel had 12 gallons before filling began.

Answers

The equation that models this situation is z = 7.9y + 12.

A linear equation is a function that has a single variable raised to the power of 1.  An example is x = 4y + 2.

Where:

2 is the constantx = dependent variable y = independent variable  

From the equation given, 12 would be the constant, the independent variable would be 7.9 and z would be the dependent variable.

z = 7.9y + 12

Here is the complete question: A barrel of oil was filled at a constant rate of 7.9 gal/min. The barrel had 12 gallons before filling began. write an equation in standard form to model the linear situation.

Answers

Answer:

[tex]k=\pm3[/tex]

Step-by-step explanation:

[...] if you can write the LHS as a perfect square, or if you can't spot a factorization of it right away, if and only if the discriminant [tex]\Delta = b^2-4ac[/tex] (or, if b is an even number, 1/4 of it) is zero.

I see it! I see it!

Stare at it for a while. First term is [tex]3(2x)^2[/tex], third term is [tex]3(1)^2[/tex], we are missing a double product, but we can play with k. For the LHS to be [tex]3(2x\pm1)^2 = 3(4x^2\pm4x+1) = 12x^2\pm12x+3[/tex] you just need [tex]4k= \pm12 \rightarrow k=\pm3[/tex].

I don't see it...

Then number crunching it is. Set the discriminant to 0, solve for k

[tex]\frac{\Delta}4 = 4k^2-12\cdot 3 =0 \rightarrow 4k^2=36 \\k^2 = 9 \rightarrow k=\pm3[/tex]
