Eva is working two summer jobs, making $16 per hour tutoring and $8 per hour clearing tables. Last week Eva worked 3 times as many hours clearing tables as she worked hours tutoring hours and earned a total of $80. Graphically solve a system of equations in order to determine the number of hours Eva worked tutoring last week, x,x, and the number of hours Eva worked clearing tables last week, yy.

[tex]\qquad[/tex] [tex]\twoheadrightarrow\bf w^2 - (10x)^2[/tex]

[tex]\qquad[/tex] [tex]\twoheadrightarrow\bf w^2 -100 x^2[/tex]

Answer: A = 15 + 0.5(w)

Step-by-step explanation: The above equation represents the amount of dollars after selling w cups of water. Remember: we also have 15 in advance, so we add that to the total amount of cups sold. We multiply 0.5 (the amount earned per water cup) by w (the number of water cups sold) and we will get our answer.

To check this, let's say we sold 10 water cups. So w = 10. Therefore, we write A = 15 + 0.5(10). That = A = 15 + 5 which A = 20. We can use any number in place of w now and we will know it is correct using this formula

Answer:

Answer:

Option A

Step-by-step explanation:

Let,

Length = 5x

Breadth = 4x

Perimeter = 2(l + b)

=> 144 = 2(5x + 4x)

=> 144 = 2(9x)

=> 144 = 18x

=> 144/18 = x

=> 8 = x

Therefore,

Length = 5x = 5(8) = 40 cm

The equation to represent the problem is written as

$456.50 = 3.5x + $159

the cost of the labor per hour is $85.

Let x be the cost of the labor per hour.

The technician worked on the computer for 3.5 hours, so the labor cost would be 3.5x.

The total cost, including the labor and parts, was $456.50.

So, we can set up an equation to represent the total cost:

Total cost = Labor cost + Parts cost

$456.50 = 3.5x + $159

Solving for x:

Subtract $159 from both sides:

$456.50 - $159 = 3.5x

$297.50 = 3.5x

Finally, divide both sides by 3.5 to find the value of x:

x = $297.50 / 3.5

x = $85

Therefore, the cost of the labor per hour is $85.

Step-by-step explanation:

When x=-1, y=5(-1)+3=-5+3=-2

When x=0, y=5(0)+3=0+3=3

When x=1, y=5(1)+3=5+3=8

When x=2, y=5(2)+3=10+3=13

When x=3, y=5(3)+3=13+3=16

Therefore, this is the correct table:

Answer:

263-5000=4737

Step-by-step explanation:

IF ITS -5000-263

if you subtract a negative to a negative it makes the negative increase. -5000-263 would end up being technically -5000+(-263). A number line would help you, because on a number line, when subtracting, you go to the left.

[-5000+(-263)=-5263]

IF ITS 263-(-5000)

do you see those two - signs? Those cross eachother out, turning it into a +, also making the -5000 not negative anymore. Making 263-(-5000) = 263+5000.

[263+5000=5263]

Answer:

Assuming that it ends at 9.5. The domain is (-8 , 9.5). However, assuming it continues further to the right, it could be (-8 , ∞)

Range is the area covered vertically. Assuming it ends at 9.5 it would be        (4 , -4) However, assuming it continues further down vertically, it would/could be (4 , -∞)

Neither.

Step-by-step explanation:

Domain is the area covered horizontally. Assuming that it ends at 9.5. The domain is (-8 , 9.5). However, assuming it continues further to the right, it could be (-8 , ∞)

Range is the area covered vertically. Assuming it ends at 9.5 it would be        (4 , -4) However, assuming it continues further down vertically, it would/could be (4 , -∞)

It is neither because it is on the x-axis.

Write an equation for each one set the equal to each other and solve.

A: 35 + 3x

B: 27.50 + 4.50x

35 + 3x = 27.50 + 4.50x

Subtract 27.50 from both sides:

7.50 + 3x = 4.50x

Subtract 3x from both sides

7.50 = 1.50x

Divide both sides by 1.50

The statement which is an example of the transitive property of congruence is C. If A EFG : AHJK, and AHJK = AMNP, then A EFG = AMNP.

This transistive property holds congruent figure. it is states that: If Figure A is equal to figure B and Figure B is equal to Figure C, then Figure A will be equated to Figure C.

For example: AB = CD; CD = EF, then AB = EF

if angle A is equivalent to angle B and angle B is equivalent to angle C; then angle A will be equivalent to angle C

Answer:

Step-by-step explanation:

slope-intercept form is y=mx+b

m = slope = change in y/change in x

  change in y/change in x = 2/1

  m = 2

b = y intercept = y value when x = 0

  using the slope, go left 2 units and down 4

  when x = 0, y = 0

  b = 0

y = mx+b when m = 2 and b = 0

y = 2x+0

y = 2x

The selling price of the item is $835.49

The given parameters are:

Original cost = $784.50

Markup = 6.5%

The selling price is calculated as

Selling price = Original cost * (1 + Markup)

So, we have:

Selling price =$784.50 * (1 + 6.5%)

Evaluate the expression

Selling price =$835.49

Hence, the selling price of the item is $835.49
