How to find the value of $x$ in an equation?

To find the value of $x$ , or any other variable, use Addition, Subtraction, Multiplication or Division. The entire process of solving an equation really boils down to these four mathematical operations.

The first operation to be used in the equation $4=\frac{x}{5}$ is Multiplication. I am going to multiply $5$ by both sides. I will end up with this as my result:

$20=x$ , or $x=20$ .

Tickets to a school play cost $2 if bought in advance and $3 at the door. By selling all 400 tickets, $1030 was collected. First

Marrrta [24]

Answer:

170 tickets.

Step-by-step explanation:

Write formulas for the question.

$N_2+N_3=400$

$2N_2+3N_3=1030$

Then use substitution.

$N_2=-N_3+400$

$2(-N_3+400)+3N_3=1030$

$-2N_3+800+3N_3=1030$

$N_3=230$

So number of $3 tickets sold is 230. But they ask for the tickets bought in advance (i.e. the tickets sold for $2). Use substitution again.

$N_2+230=400\\N_2=400-230\\N_2=170$

<h2>Answer:</h2>

Cost of basketball sneakers with tax = $96.12

Amount of tax = 8% of cost price

= 8/100 × 96.12

Cost of sneakers without tax = $96.12 - $7.6896.

= $88.43.

In △ABC, m∠A=16°, m∠B=49°, and a=4. Find c to the nearest tenth.

xenn [34]

Answer:

= 8.33 inches

Step-by-step Explanation

First add 49 + 16, which equals 65, and subtract that result from 180, since a triangle equals 180 degrees and you find out angle C is equal to 115 degrees.

Now using the formula sinA/a = sinB/b = sinC/c, plug in values and you'd get the equation sin49 x 10/sin115. After solving the equation you'd get about 8.32729886047258 inches.

= 8.33
