Answer:

Addition Property of Equality

Division Property of Equality

Step-by-step explanation:

So we have the equation:

[tex]3x-4=-10[/tex]

Addition Property of Equality

Add 4 to both sides:

[tex](3x-4)+4=(-10)+4\\3x=-6[/tex]

Division Property of Equality

Divide both sides by 3:

[tex](3x)/3=(-6)/3\\x=-2[/tex]

And that's our answer :)

Answer:

The average cost this year = $33,093.75

Step-by-step explanation:

The computation of the average cost this year is shown below:

Given that

The average cost for the last year = $31,250

Increased percentage = 5.9%

Based on the above information, the average cost this year is

= The average cost for the last year × (1 + Increased percentage)

= $31,250 × (1 + 0.059)

= $31,250 × 1.059

= $33,093.75

Answer:

P(t) = 10t - 400

Step-by-step explanation:

Selling price of each ticket = $10

Cost of setting up the dance= $400

Profit = Revenue - cost

Revenue = price × quantity

Revenue that will maximize profit = 10t

where t= quantity of tickets that maximises profits

Cost = $400

Profit(t) = Revenue - cost

P(t)= 10t - 400

We want to find the equation that represents the school's profit. We will get:

P(x) = $10*x - $400

We know that the tickets to the school dance are sold for $10 each, then the revenue, if they sell x tickets, is just:

r(x) = $10*x

And we know that they spent a total of $400.

Remember that profit is defined as the difference between revenue and costs, so the profit equation is just:

P(x) = $10*x - $400

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

First of all to find the equation of the line we must first find the slope.

The slope of the line using points

(0,-2) (8,-4) is

Now using one of the points and the slope we can find the equation of the line.

Equation of the line using point (0 , - 2) and slope - 1/4 is

Answer:

2.6i

Step-by-step explanation:

undo the - by making it:  √-6.76= √6.76 x  √-1

then,  √-1 would be converted to imaginary number -> i

now rewrite it as  √6.76 x i or i√6.76 which is the same as the squareroot of 6.76 which is 2.6 times i.

Then just write your final answer as 2.6i

Answer:

3/5 c + 70 = 1650.

Step-by-step explanation:

If c is the number of calories in the cheeseburger, we can see that the entire number of calories for the meal is 3/5 c + 70 = 1650.

If we want to isolate c, we can subtract both sides by 70.

3/5 c = 1580

Answer:

C = [5(1650 - 70)]/3

Step-by-step explanation:

We write the equation: 1650 = 70 + 3C/5

Subtract 70 from both sides: 1650 - 70 = 3C/5

Multiply 5 on both sides: 5(1650 - 70) = 3C

Divide 3 on both sides : C = [5(1650 - 70)]/3

Answer:

The answer is B. 50°

Step-by-step explanation:

Got 100% on the test :)

The value of ∠MHJ is 50°. Therefore, option B is the correct answer.

We need to find the value of ∠MHJ.

Vertically opposite angles are angles that are opposite one another at a specific vertex and are created by two straight intersecting lines. Vertically opposite angles are equal to each other.

Here, ∠MHJ and ∠KHL are two vertically opposite angles.

So, (x+15)°=(2x-20)°

⇒x=35°

Now, ∠MHJ=(2x-20)°=50°

Therefore, option B is the correct answer.
