4 0

Answer:

11

Step-by-step explanation:

Let the number be x

2x + 14 = 4x - 8                  Add 8 to both sides

2x + 14 + 8 = 4x                 Combine

2x + 22  = 4x                     Subtract 2x

22 = 2x                              Divide by 2

11 = x

In ABC, if the lengths of sides a and c are 8 centimeters and 16 centimeters, respectively, and the measure of C is 35 degrees,
Simora [160]

Answer:

∠ A ≈ 16.67°

Step-by-step explanation:

Using the Sine rule in Δ ABC

\frac{a}{sinA} = \frac{c}{sinC} , substitute values

\frac{8}{sinA} = \frac{16}{sin35} ( cross- multiply )

16 sinA = 8 sin35° ( divide both sides by 16 )

sin A = \frac{8sin35}{16} , thus

∠ A = sin^{-1} ( \frac{8sin35}{16} ) ≈ 16.67° ( to 2 dec. places )

Identify the algebraic expression for the following: the quotient of 12 and a number y increased by 7
Goshia [24]

The algebraic expression for the given word problem is 12/y + 7

<h3>Writing an expression</h3>

From the question, we are to write the algebraic expression for the given word problem

The given word problem is

"the quotient of 12 and a number y increased by 7"

First,

"the quotient of 12 and a number y" can be expressed as

12/y

Then,

"the quotient of 12 and a number y increased by 7" becomes

12/y + 7

Hence, the algebraic expression for the given word problem is 12/y + 7
