fgiga [73]3 years ago
6 0

Answer:

There is one solution

Step-by-step explanation:

You can tell by looking at it that 2x and 3x are different. Both are obtained once the brackets have been removed. So you will get just one answer.

2(x -1) = 3(x - 4)                  Remove the brackets.

2x - 2 = 3x - 12                  Subtract 2x from both sides.

2x - 2x - 2 = 3x - 2x - 12   Combine

-2 = x -12                           Add 12 to both sides.

-2 + 12 = x -12 +12             Combine

10 = x

The cylindrical water tank on a semitrailer has a length of 20 feet. The volume of the tank is equal to the product of pi, the s
Bogdan [553]

Answer:

V = 20πr²

Step-by-step explanation:

In this question, volume of the cylindrical tank has been defined as,

Volume V of the tank = Product of π, the square of the radius of the tank 'r' and the length of the tank 'h'.

Therefore, formula to calculate the formula will be,

V = πr²h

If the length of the cylindrical trailer is,

h = 20 feet

Then the volume of the trailer will be,

V = πr²(20)

V = 20πr²

HELP PLSSSS!!! I will mark you as brainlyist

X = 15°

Given that the angle with m < 165° and m< x° are supplementary angles whose sum add up to 180°,

We can add their sum by establishing the following formula:

m < 165° + x° = 180°
Subtract m< 165° from both sides

m < 165° — m < 165° + x° = 180° — m < 165°

x° = 180° — m < 165°

x° = 15°

Therefore, the value of x = 15 °

PQRS is a parallelogram. Find the values of a and b. Solve for the value of c, if c=a+b.
Serjik [45]

Answer:

i. a = 7

ii. b = 7

iii. c = 14

Step-by-step explanation:

1. In a parallelogram, the pair of opposite sides are equal, thus;

6a + 10 = 8a -4

4 + 10 = 8a - 6a

14 = 2a

Divide both sides by 2,

a = 7

2. <SPQ + <PSR = 180^{0}

(18b - 11) + (9b + 2) =  180^{0}

18b + 9b + 2 -11 =  180^{0}

27b -9 =  180^{0}

27b =  180^{0} + 9^{0}

27b = 189^{0}

Divide both sides by 27,

b = 7

Therefore,

c = a + b

  = 7 + 7

  = 14

c = 14
