Answer:

Step-by-step explanation:

5+2(3+2x) = x + 3(x+1)

simplify

5 + 6 + 4x = x + 3x + 3

simplify once more

11 + 4x = 4x + 3

subtract 3 from both sides

8 + 4x = 4x

divide by 4

2 + x = x

no solution, because it is saying x equals something larger than x

Answer: B) 5 + 2(3 + 2x) = x + 3(x + 1)

<u>Step-by-step explanation:</u>

A) 4(x + 3) + 2x = 6(x + 2)

4x + 12 + 2x = 6x + 12

6x + 12 = 6x + 12

infinitely many solutions

B) 5 + 2(3 + 2x) = x + 3(x + 1)

5 + 6 + 4x = x + 3x + 3

11 + 4x = 4x + 3

11 = 3

FALSE

No Solution

C) 5(x + 3) + x = 4(x + 3) + 3

5x + 15 + x = 4x + 12 + 3

15 + 6x = 4x + 15

15 + 2x = 15

2x = 0

x = 0

One Solution

D) 4 + 672 + x = 2(3x + 8)

676 + x = 6x + 16

660 = 5x

180 = x

One Solution

A map of a rectangular park has a length of 4 inches and a width of 6 inches. It uses a scale of 1 inch for every 30 Miles. What

andre [41]

Answer:

Step-by-step explanation:

Dimensions of the rectangular park = 4 inches by 6 inches

Since scale factor = $\frac{\text{Dimensions of the park on map}}{\text{Dimensions of the original park}}$ = $\frac{1}{30}$

$\frac{4}{\text{Length of the original park}}=\frac{1}{30}$

Length of the original park = 120 miles

Similarly, width of the park = 180 miles

Area of the park = Length × Width

= 120 × 180

= 21600 square miles

Therefore, area of the original park is 21600 square miles.

Formula for the ratio of area of the park on map and original park is,

$\frac{\text{Area of the park on map}}{\text{Area of the original park}}=(\text{Scale factor})^2$

$\frac{6}{21600}=(\text{Scale factor})^2$

Scale factor = $\sqrt{\frac{1}{3600}}$

= $\frac{1}{60}$

Scale factor to reproduce the map so that it fits in the brochure will be 1 inch for every 60 miles.

It's D.
.
Why?
.
Ok, your variable is x.
.
x stands for WHAT( the VALUE ) that you want to find.
.
So, assume you know what x is.
.
Pretend it's 10 or like infinity or what-not.
.
So, x + $32.25 = $45.32.
.
But you don't know x.
.
But it's easy to find it.
.
Subtract $32.25 on both sides, and BOOM!!
.
Hope this helped!.
.
Any question, ASK AWAY!!
