What is the value of x in the equation 0.75x+3=6(x-3)?

Mathematics
1 answer:
cluponka [151]3 years ago
4 0

Answer:

x = 4

Step-by-step explanation:

Given

0.75x + 3 = 6(x - 3) ← distribute

0.75x + 3 = 6x - 18 ( subtract 0.75x from both sides )

3 = 5.25x - 18 ( add 18 to both sides )

21 = 5.25x ( divide both sides by 5.25 )

4 = x

a team's stadium has a capacity of 86,047. The fan base is notorious for selling out of tickets every game. If every game sells
ycow [4]

Answer:

1,032,564 tickets

Step-by-step explanation:

Find how many tickets they sell in total by multiplying the capacity of the stadium by the number of games in the season:

86,047(12)

= 1,032,564

So, if every game sells out, 1,032,564 tickets will be sold.

Solve for x: 3(x + 1) = −2(x − 1) − 4
Anika [276]
Solve your equation step-by-step.

3(x+1)=−2(x−1)−4


Simplify both sides of the equation.

3(x+1)=−2(x−1)−4

Simplify:

3x+3=−2x−2

Add 2x to both sides.

3x+3+2x=−2x−2+2x

5x+3=−2

Subtract 3 from both sides.

5x+3−3=−2−3

5x=−5

Divide both sides by 5.

5x/5 = −5/5

x=−1

If A = 30° and r = 12, find x. (Round your answer to the nearest whole number.)
Margaret [11]

Answer:

\boxed{12}

Step-by-step explanation:

A = 30° and r = 12

\sin A = \frac{r}{r + x}

\sin 30 = \frac{12}{12 + x}

\frac{1}{2} = \frac{12}{12 + x}

1(12 + x) = 2(12)

12 + x = 24

x = 24 - 12

x = 12

.
