Step-by-step explanation:

Given

$\frac{4}{77}=\frac{12}{x}$

Cross Multiply

$x \times 4=12\times 77\\x=\frac{12\times 77}{4} \\x= 3\times 77\\x= 231$

Therefore x=231

ira [324]

Answer:

$y\approx75.0$ is the correct answer.

Step-by-step explanation:

$\tan \left(30^{\circ \:}\right)=\frac{x}{150}\quad :\quad x=50\sqrt{3}\quad \left(\mathrm{Decimal}:\quad x=86.6\dots \right)\\\\\sin \left(60^{\circ \:}\right)=\frac{y}{86.6}\quad \rightarrow\quad y\approx75$

three consecutive intergers have a sum of 30. Which equation can be used to find x, the value of the smallest of three numbers

prohojiy [21]

Answer:

x+ x+1 + x+2 = 30

3x+3 =30

Step-by-step explanation:

Let x be the smallest integer

x+1 be the next smallest

x+2 be the third

x+ x+1 + x+2 = 30

Combine like terms

Part A

OLEGan [10]

Part A: The algebraic equation for the situation is 2x - 3 = 5

Part B: Bob has 4 brand new music CD's

Step-by-step explanation:

Translate the situation into an algebraic equation:

Ann has 5 brand new music CD’s, which is 3 less than twice the amount that Bob (x) has
Find the value of x (the number of brand new CD's Bob has)

Part A:

∵ Bob has x brand new CD's

∵ Ann has 5 brand new music CD’s, which is 3 less than twice

the amount that Bob has

- That means multiply x by 2 and then subtract 3 from the product

and equate the answer by 5

∵ Twice x 2x

∵ 3 less than twice x = 2x - 3

∴ 2x - 3 = 5

The algebraic equation for the situation is 2x - 3 = 5

Part B:

Let us solve the equation to find the value of x

∵ 2x - 3 = 5

- Add 3 to both sides

∴ 2x = 8

- Divide both sides by 2

∴ x = 4

Bob has 4 brand new music CD's
