Bruce does have enough money to buy the video game.

x/42 = 30/100

x=12.60 - This is the amount of money the video game is without tax

x/12.60 = 5/100

x=0.63 - sales tax amount

0.63+12.60=13.23 - amount of video game with tax

_3x_13 =_7x+15 what is the an<br><br><br><br><br>​
Tema [17]

Answer:

<h2><u><em>x = -7</em></u></h2>

Step-by-step explanation:

_3x_13 =_7x+15 what is the anSWER?

assuming that the underscore is a minus and you are looking for the x value.

-3x - 13 = -7 + 15

-3x = -7 + 15 + 13

-3x = 8 + 13

-3x = 21

x = -7

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

check

-3 * (-7) - 13 = -7 + 15

21 - 13 = 8

8 = 8

<u><em>the answer is good</em></u>

5. (-8, 1) and (0, -5)<br>6. (-3,-8) and (2,7)<br> write both equations in slope intercept form​
Cerrena [4.2K]

Slope-intercept form is as shown here: y = mx + b

(-8, 1) and (0, -5) in slope-intercept form will be y = -3/4x - 5

(-3, -8) and (2, 7) in slope-intercept form will be y = 3x + 1

Giải phương trình:<br> sin*2x+sinxx.cox=1/2
creativ13 [48]

Answer:

x = 9.47 degrees  ( in first quadrant.

Step-by-step explanation:

sin2x + sinx cos x = 1/2

Now sinx cos x = 1/2sin2x so:

3/2sin2x = 1/2

sin2x = 1/2 / 3/2

sin2x = 1/2 * 2/3 = 1/3

2x = arcsin 1/3 = 19.47 degrees

x = 9.74 degrees to nearest hundredth.

The cost for 15 cases of oranges is $75. What is the cost for 1 case? *
postnew [5]

Answer:Ok I This question can be solved using a system of equation, which requires translating the above word problem into something that can be algebraically

Let O=oranges and  Let G=Grapefruit

5O +8G=235

3O + 2G=85

To solve, you must isolate one of the variables and then work from there. To do that multiply both sides of the bottom or second equation by four and then subtract the bottom equation from the top.

Which would look like this

5O +8G=235

12O + 8G= 340

Then subtract the bottom from the top to get this

-7O=-105

Solving for O we divide both sides by -7, and end up with O=15

Plugging that value back into one of our original equations to solve for G we get this

3(15) + 2G= 85

45 +2G=85

2G=40

G=20

So 1 case of each altogether would equal 15+20, or $35.

<h3>Hope this helps have a awesome night/day❤️✨</h3>
