Answer:

x = 27

Step-by-step explanation:

To isolate x, we can multiply it by the reciprocal of the fraction (-3/2). We do the same to the -18.

Through cross-multiplication, -18/1 x -3/2 simplifies into -9/1 x -3/1 (because 2 goes into 2 once and 2 goes into -18 -9 times).

-9 x -3 = 27; therefore, x = 27

Answer:

X= 27

Step-by-step explanation:

Muliply by the reciprocal to get rid of the fraction on the right.

(-3/2)-18=(-2/3)(-3/2)x

Simplify by multiplying the fractions. The left makes 54/2 and the right makes x because the reciprocals cancel each other out.

54/2=x

Simplify your fraction by dividing 54 by 2

Triangle ABC is an isosceles triangle, and side BC is congruent to side AC. If side AC equals 40 centimeters, and AB is one-half

Alik [6]

Answer:

100 cm

Step-by-step explanation:

Given:

AC = BC

AC = 40

2AB=AC

Simplify:

BC = 40

Simplify:

2AB = 40

Algebra:

AB = 20

Here's the sides:

AB = 20

AC = 40

BC = 40

Add all of them together:

100

An animal shelter spends three dollars per day to take care for each bird and seven dollars per day take care for each cat Alexa

NikAS [45]

Answer:

There were 16 birds at the shelter on Wednesday.

Step-by-step explanation:

Number of cats and birds on Wednesday = 34

let the number of birds on Wednesday = b

Then number of cats = (34 -b)

The rate of taking care of each bird in shelter = $3

The rate of taking care of each cat in shelter = $7

Total amount spent by shelter on Wednesday = $174

So, according to the question

b x ($3) + (34 -b) ($7) = $ 174

or, 3b + 238 - 7b = 174

or, 4b = 64

⇒ b = 64/4 = 16

Hence, the number of birds in shelter on Wednesday = b = 16

and Number of cats = 34 - 16 = 18
