3 0

Answer:

All real numbers less than 7

Step-by-step explanation:

Let

x ----> the number

we know that

The inequality that represent the situation is

7x < 49

Solve for x

Divide by 7 both sides

x < 49/7

x < 7

The solution is the interval -----> (-∞, 7)

All real numbers less than 7

miskamm [114]
Assume you mean 3x^2 when you typed the question.

3x^2+14x+16=0
(3x+8)(x+2)=0

x=-8/3 or -2

You and a friend went to the movies.You spent half your money on tickets. Then you spent 1/4 of the money on popcorn, $2 on cand
bagirrra123 [75]

Answer:

We took $ 24 to the movies.

Step-by-step explanation:

Let total money be

On movies = Half of the money =\frac{x}{2}

On popcorn =  \frac{x}{4}

on candy = $2

On soda = $3

total money spent =  \frac{x}{2} +\frac{x}{4}+ 2+3+1

         x   =  \frac{x}{2} +\frac{x}{4}+ 2+3+1

x- \frac{x}{2} -\frac{x}{4} = 6

\frac{x}{1} -\frac{x}{2} - \frac{x}{4}  =6

    \frac{4x-2x-x}{4}  = 6\\          \frac{x}{4} =6\\x =24

(Law of Sines)
Mariana [72]

Answer:

Option (D) is correct.

Step-by-step explanation:

In a triangle BCD , with b, c, d as the sides of triangle.

Sine rule states when we we divide side b by the sine of angle B then it is equal to side c divided by the sine of angle C and also equal to side d divided by the sine of angle D.

Using Sine rule,

\frac{b}{\sin B}=\frac{c}{\sin C}=\frac{d}{\sin D}

Consider the first and third ratio,

\frac{b}{\sin B}=\frac{d}{\sin D}

Substitute the values of d = 3 , b= 5 and ∠D=25°

\Rightarrow \frac{5}{\sin B}=\frac{3}{\sin 25^{\circ}}

\Rightarrow \sin B=\frac{\sin 25^{\circ} \times 5}{3}}  

 \Rightarrow \sin B=45,135

Thus, Measure of angle B is 45 and 135 as sinB is positive is first and 2nd quadrant.

Thus, option (D) is correct.
