Answer:5

Step-by-step explanation:

Simplifying

8x + -20 = 3x + 5

Reorder the terms:

-20 + 8x = 3x + 5

Reorder the terms:

-20 + 8x = 5 + 3x

Solving

-20 + 8x = 5 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-20 + 8x + -3x = 5 + 3x + -3x

Combine like terms: 8x + -3x = 5x

-20 + 5x = 5 + 3x + -3x

Combine like terms: 3x + -3x = 0

-20 + 5x = 5 + 0

-20 + 5x = 5

Add '20' to each side of the equation.

-20 + 20 + 5x = 5 + 20

Combine like terms: -20 + 20 = 0

0 + 5x = 5 + 20

5x = 5 + 20

Combine like terms: 5 + 20 = 25

5x = 25

Divide each side by '5'.

x = 5

Simplifying

x = 5

There were toy cars,dolls and teddy bears in a shop. 30% of the toys were toy cars. The ratio of the number of dolls to the numb
klemol [59]

Answer:

80 toy cars were left in the shop.

Step-by-step explanation:

Since there were toy cars, dolls and teddy bears in a shop, and 30% of the toys were toy cars, and the ratio of the number of dolls to the number of teddy bears were 4: 1, and there were 156 more dolls than toy cars, and after some toy cars were sold, 16% of the remaining toys in the shop were toy cars, to determine how many toy cars were left in the shop the following calculation must be performed:

Toy cars = 30%

Dolls and teddy bears = 70%

70/5 = 14 x 4 = 56

Dolls = 56%

Teddy bears = 14%

56 - 30 = 26

156/26 = 6 (1%)

Toy cars = 30 x 6 = 180

Dolls = 56 x 6 = 336

Teddy bears = 84

100 - 16 = 84

84 = 336 + 84 = 420

16 = X

84 = 420

16 = X

16 x 420/84 = X

80 = X

Therefore, 80 toy cars were left in the shop.
