4. The sequence of calculation
a) 3+ 4=7
b) 7 * 36 = 252
c) 252 - 5 = 247
can be replaced by
(3+4) 36-5-247.
By proceeding as above, express each
sequence of operations by one equality:
a) 3 + 8 = 11 : 11* 10 = 110
b) 3X 6 = 18 : 18x 40 = 720
c) 4x 80 = 320 : 320 - 12 = 308 :
308 + 34 = 342
d) 5x 70 = 350 ; 40 + 12 = 52 ;
350 - 52 = 298​

Answer:

  k = 54/79

Step-by-step explanation:

You can eliminate fractions by multiplying both sides by 12.

  15(2 -k) = 24(3k -1) -8k

  30 -15k = 72k -24 -8k

  54 = 79k

  54/79 = k

Answer:

72 cm²

Step-by-step explanation:

Given the ratio of diameters = a : b , then

ratio of areas = a² : b²

Here the ratio of diameters = 2 : 5 , then

ratio of areas = 2² : 5² = 4 : 25

let x be the area of smaller circle then using proportion

[tex]\frac{25}{450}[/tex] = [tex]\frac{4}{x}[/tex] ( cross- multiply )

25x = 1800 ( divide by 25 )

x = 72

That is the area of the smaller circle is 72 cm²

Answer:

-1/m^3

Step-by-step explanation:

m-3n/6m^3n - m+3n/6mn^3

=(m-3n)-(m+3n)/6m^3n  [6m^3n is the L.C.M]

=m-3n-m-3n/6m^3n

=-6n/6m^3n

= -1/m^3

Answer:

Each game costs $1.28.

Step-by-step explanation:

First, we need to find the total of all the games.

Since the only additive is the $0.50, we simply subtract it from the total.

4.35-0.50=$3.85

Since you bought three games, and they're all the same price, we divide $3.85 by 3.

3.85/3=1.2833333

Since were doing it by pennies, we can round it down to $1.28 per game.

Hope this helps!

Answer:

$1.28 per game.

Answer:

The fastest car on Earth, a British-made Thrust SSC, would win every ... The fastest train on Earth, the TGV from France, can travel at faster speeds than trains in the United States. During a speed test, the train traveled 800 miles in 2.5 hours. What is its ... Based on this speed.

Step-by-step explanation:

The speed of the train is 320 miles per hour.

Speed is the ratio of the given distance and time.

It shows how fast an object is moving at a given time.

The formula is Distance / Time.

We can find the distance or time when the required values is given using this formula.

We have,

The speed of the TGV train can be calculated using the formula:

Speed = distance/time

where distance is given in miles and time is given in hours.

In this case,

The distance traveled by train is 800 miles, and the time taken to travel this distance is 2.5 hours.

Substituting these values into the formula, we get:

Speed = 800 miles / 2.5 hours

Simplifying the expression on the right-hand side, we get.

Speed = 320 miles per hour

Therefore,

The speed is 320 miles per hour.

Answer:

x= -7/12

Step-by-step explanation:

Subtract the numbers

-3x+2-5x-7=4x+2

-3x-5-5x=4x+2

Combine like terms

-3x-5-5x=4x+2

-8x-5=4x+2

Add 5 to both sides of the equation

-8x-5=4x+2

Step-by-step explanation:

[tex] \frac{ \sin(56) }{4} = \frac{ \sin(x) }{4.5} \\ \sin(x ) = \frac{4.5 \times \sin(56) }{4} = \frac{3.73}{4} \\ \sin(x) = 0.9326 \\ x = 68.84[/tex]

Hence, the value of x is 68.84 degrees.

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs, and sometimes the arms of the angle.

we know sine rule,

[tex]\frac{sin(56)}{4} = \frac{sin(x)}{4.5}[/tex]

sin(x) = [tex]\frac{(4.5).sin(56)}{4}[/tex] = [tex]\frac{3.73}{4}[/tex]

sin(x) = 0.9326

x = 68.84
