A parking garage has 6 levels. Each level has 15 rows. Each row has the same number of parking spaces. There are 2,250 parking s

VladimirAG [237]

Answer:

$25$

Equation: $90x=2250$

Step-by-step explanation:

Let parking spaces in each row $=x$

In $1$ level there are $15\ rows$ so total number of parking spaces in 1 level $=15\times x=15x$

There are $6$ level so total number of parking spaces $=6\times 15x=90x$

$90x=2250\\\\x=\frac{2250}{90}\\\\x=25$

14. Michelle simplified an expression for the perimeter of the rectangle below and got X + 35.

Zigmanuir [339]

Answer:

The correct expression for the perimeter is $P=(\frac{5}{3}x+70)\ units$

see the explanation

Step-by-step explanation:

The complete question in the attached figure

Let

L ----> the length of rectangle

W ---> the width of rectangle

we know that

The perimeter of rectangle is equal to

$P=2(L+W)$

In this problem we have

$L=(\frac{5}{6}x+23)\ units$

$W=12\ units$

substitute the values

$P=2(\frac{5}{6}x+23+12)$

$P=2(\frac{5}{6}x+35)$

$P=(\frac{10}{6}x+70)\ units$

Simplify

$P=(\frac{5}{3}x+70)\ units$

so

Michelle didn't multiply the sum of length and width by 2

Solve the following equation. Show all your work.

horrorfan [7]

$\dfrac{x}{x - 2} + \dfrac{x - 1}{x + 1} = -1$

$(x - 2)(x + 1) \times \dfrac{x}{x - 2} + (x - 2)(x + 1) \times \dfrac{x - 1}{x + 1} = -1(x - 2)(x + 1)$

$(x + 1)x + (x - 2)(x - 1) = -1(x - 2)(x + 1)$

$x^2 + x + x^2 - 3x + 2 = -x^2 + x + 2$

$3x^2 - 3x = 0$

$3x(x - 1) = 0$

$x = 0~~~or~~~x - 1 = 0$

$x = 0 ~~~ or ~~~ x = 1$

Since neither 0 nor 1 cause a zero in a denominator in the original equation, 0 and 1 are acceptable as solutions.

Answer: x = 0 or x = 1
