A car cost $18,000, which is 9/10 of the cost of an apartment. A motorcycle cost 1/5 of the cost of the apartment or 4/5 of the

blagie [28]

Answer:

$1500

Step-by-step explanation:

let the cost of the apartment = x

Hence the cost of the car is $\frac{9}{10} \times x$

also given the cost of car=18000

Hence

$18000= \frac{9x}{10}$

$x= \frac{18000 \times 10}{9}$

$x= 2000 \times 10$

$x= 20000$

Motorcylce cost = $\frac{1}{5}$ of Cost of apartment

= $\frac{1}{5} \times 20000$

= $4000$

Also Motorcylce cost= $\frac{4}{5}$ of the cost of 100 soccer balls.

Hence

4000= $\frac{4}{5}$ x (cost of 100 soccer balls.)

(cost of 100 soccer balls.)= $\frac{4000 \times 5}{4}$

(cost of 100 soccer balls.)= $1000 \times 5$

cost of 100 soccer balls= $5000$

cost of 1 soccer balls = $\frac{5000}{100}$

cost of 1 soccer balls = 50

cost of 30 soccer balls = 50 x 30

cost of 30 soccer balls = 1500

Hence the cost of 30 balls is $1500

Solve the equation. 4x – 2 = -3x2 + 3x x = [ ? ],

Sergio039 [100]

Answer:

$x = - 4$

Step-by-step explanation:

$4x - 2 = - 3 \times 2 + 3x$

Calculate the product:

$4x - 2 = - 6 + 3x$

Rearrange the terms:

$4x - 3x = - 6 + 2$

Combine like terms:

$x = - 6 + 2$

Calculate:

$x = - 4$
