The algebraic expression of the given sentence is: 7(x - 1).

<h3>How to Write an Algebraic Expression?</h3>

Let the unknown number be represented as x.

The word "difference" means subtraction which is "-". Multiplied means times.

We would have the following:

"Difference of x and 1" is: x - 1

x - 1 multiplied by 7 would be: 7(x - 1)

6. Solve the the following system of equations: 4y+2x=14 2y+2x=10
Inessa05 [86]
4y+2x=14 ==> multiply this 1st equation by (-1) => -4y-2x=-14
Now add it up to the 2nd equation
-4y-2x=-14
 2y+2x=10
--------------    And now add them up
-2y +0x=-4
==> -2y=-4==> 2y = 4 &    y=2                   
Last step: plug y into any equation & you will find x=3

RSB [31]

Answer: ΔKE = 760.5 Joules

Step-by-step explanation:

Isnt the formula for ΔKE = 0.5m*v^2???

Im not going to use that formula you gave me, its wrong.

900/2 = 450

1.3^2 = 1.69

450 x 1.69 = 760.5 Jules

This is also the wrong subject btw
