If 8 cakes cost $62.40, how much would 3 cakes cost?

Ilya [14]

Answer:

Step-by-step explanation:

Given,

Cost price of 8 cakes = $62.40

So,

Cost price of 1 cake = $ $\frac{62.40}{8}$

Therefore,

Cost price of 3 cakes

= $( $\frac{62.40}{8}$ × 3)

[On dividing 62.40 by 8]

= $(7.80 × 3)

[On multiplying]

= $23.40

Hence,

The required cost of 3 cakes is $23.40 (Ans)

Step-by-step explanation:

Time taken/ period, T :

${ \sf{T = \frac{distance}{speed} }}$

substitute the variables:

${ \sf{T = \frac{8482}{(200 \times 1000)} }} \\ \\ { \sf{T =0.042 \: hours }}$

In seconds:

${ \sf{T = (0.042 \times 3600) \: s}} \\ { \sf{T = 152.7 \: seconds}}$

Simply the expression given below (3x^3+4x^2+4x-12)+(-5x^3+9x^2-9x+20)

Svet_ta [14]

Answer:

1. Simplify: (4x2 - 2x) - (-5x2 - 8x).

Solution:

(4x2 - 2x) - (-5x2 - 8x)

= 4x2 - 2x + 5x2 + 8x.

= 4x2 + 5x2 - 2x + 8x.

= 9x2 + 6x.

= 3x(3x + 2).

Answer: 3x(3x + 2)
