Problem 1 Answer: $x=10$

<u>Simplify both sides of the equation</u>

<u></u> $(2)(x)+(2)(-3)=14(Distribute)$ <u></u>

<u></u> $2x+-6=14$ <u></u>

<u></u> $2x-6=14$ <u></u>

<u></u>

<u>Add 6 to both sides</u>

$2x-6+6=14+6$

$2x=20$

<u></u>

<u>Divide both sides by 2</u>

<u></u> $2x/2=20/2$ <u></u>

<u></u> $x=10$ <u></u>

----------------------------------------------------------------

Problem 2 Answer: $x=-7$

<u></u>

<u>Simplify both sides of the equation</u>

<u></u> $(-5)(x)+(-5)(-1)=40(Distribute)$ <u></u>

<u></u> $-5x+5=40$ <u></u>

<u></u>

<u>Subtract 5 from both sides</u>

<u></u> $-5x+5-5=40-5$ <u></u>

<u></u> $-5x=35$ <u></u>

<u></u>

<u>Divide both sides by -5</u>

<u></u> $-5x/5=35/-5$ <u></u>

<u></u> $x=-7$ <u></u>

----------------------------------------------------------------

Problem 3 Answer: $x=-8$

<u></u>

<u>Simplify both sides of the equation</u>

<u></u> $(12)(x)+(12)(10)=24(Distribute)$ <u></u>

<u></u> $12x+120=24$ <u></u>

<u></u>

<u>Subtract 120 from both sides</u>

<u></u> $12x+120-120=24-120$ <u></u>

<u></u> $12x=-96$ <u></u>

<u></u>

<u>Divide both sides by 12</u>

<u></u> $12x/12=-96/12$ <u></u>

<u></u> $x=-8$ <u></u>

----------------------------------------------------------------

Problem 4 Answer: $x=-1/2$

<u></u>

<u>Move all terms to the left:</u>

<u></u> $2(x+6)-(11)=0$ <u></u>

<u></u>

<u>Multiply parentheses</u>

<u></u> $2x+12-11=0$ <u></u>

<u></u>

<u>Add all the numbers together, and all the variables</u>

<u></u> $2x+1=0$ <u></u>

<u></u>

<u>Move all terms containing x to the left, all other terms to the right</u>

<u></u> $2x=-1\\x=-1/2$ <u></u>

----------------------------------------------------------------

A band's first song is 4 minutes, 12 seconds long and has 462 beats. The band wants to have a second song that is 3 minutes, 54

dimulka [17.4K]

Answer:

429 beats

Step-by-step explanation:

The number of beats is proportional to the time of the song.

Convert the time to seconds to avoid recurring decimals.

4 minutes 12 seconds = 4×60+12=252 seconds

3 minutes 54 seconds = 4×60−6=234

seconds

Set up a direct proportion using equivalent fractions:

x234=462/252

←beats/←seconds

x=234×462/252

x=429 beats
