Ok so I created a equation to see how many seconds can you go to get to 180. The equation is 0.4x = 180 and I got 450. Now I concluded from this result the inequality is A, x < 450 because unless you want your submarine to crash in the seafloor you should probably stop before 450 seconds.

The perimeter of a rectangle is 15x + 17 y if the length is 7/2x + 7y then find the width of the rectangle A) 4x + 3/2y B) 8x +
tigry1 [53]
The equation for the perimeter of a rectangle:

P = 2L + 2W

We’re given P and L and asked to find W:

15x + 17y = 2(7/2x + 7y) + 2W
15x + 17y = 7x + 14y + 2W
2W = 8x + 3y
W = 4x + 3/2y

Answer is A.

Problem #7 PLEASE HELP ;(

Answer:

Yes

6(x+0.4) is equivalent to 3(2x+0.8)

Step-by-step explanation:

Given in the questions two expressions

6(x + 0.4)

3(2x + 0.8)

We will apply distributive law

It is a law relating the operations of multiplication and addition, stated symbolically

<h3>a(b + c) = ab + ac</h3><h3 />

6(x + 0.4)

= 6(x) + 6(0.4)

= 6x + 2.4

3(2x + 0.8)

= 3(2x) + 3(0.8)

= 6x + 2.4

Since both equations when expanded have same answers, hence they are equivalent
