To stock your school store, you buy a total of 25 sweatshirts and hats for $172.50. You pay $8.00 per sweatshirt and $2.50 per hat. How many of each item do you buy?

Answer:

y = -3x + 10

Step-by-step explanation:

6x+2y=20

First, you want to subtract 6x from both sides.

2y=-6x+20

Now, you want to divide by 2 on both sides because you want to get y by itself.

y = -3x + 10

Answer:

Y = -3x + 10

Step-by-step explanation:

Subtract the 6x from both sides to get y by itself

You would have 2y=-6x+20

Divide everything by 2 for the correct formula format

You would have y=-3x+10

Step-by-step explanation:

Answer:

Expression gives the perimeter = 4x√17

Step-by-step explanation:

∵ The diagonals of the rhombus ⊥ to each other and

  bisects each other

∴ Half the longest diagonal = 8x/2 = 4x

∴ Half the shortest diagonal = 2x/2 = x

Use Pythagoras theorem to find the length of the side of the rhombus

∴ The length of the side = √[(4x)² + (x)²] = √[16x² + x²] = √(17x²)

∴ S = x√17

∵ Perimeter of the rhombus = 4 × S

∴ P = 4 × x√17 = 4x√17

Answer:

the correct answer is 4x✓13.

Answer:

Your solution is (-10, 6).

Step-by-step explanation:

Combining the equations is also known as substitution. This is done when you substitute one variable into another equation.

-5x + y = 56

x + y = -4

Let's change the second equation into one with one variable on each side.

y = -x - 4

Now, plug this into your first equation.

-5x + (-x - 4) = 56

Distribute the + sign.

-5x - x - 4 = 56

Combine the like terms.

-6x - 4 = 56

-6x = 60

Isolate x by dividing both sides by -6.

x = -10

Now plug this back into either equation.

-10 + y = -4

Add 10 to both sides to find y.

y = 6

Your solution is (-10, 6).

Check this by plugging in these values into the equation you have not checked yet.

-5(-10) + (6) = 56

50 + 6 = 56

56 = 56

Your solution is correct.

Hope this helps!

Answer:

x=-10; y=6

Step-by-step explanation:

combine the equations:

-5x + y + x + y = 56 +(-4)

-4x + 2y = 52

add 4x to each side

2y=52+4x

divide by 2

y=26+2x

now substitute 26+2x for y in the second equation:

x + 26 + 2x = -4

3x + 26 = -4

3x = -30

x = -10

therefore y = 6

Answer:

7x = 35cm ; 2x = 10cm

Step-by-step explanation:

7x and 2x are the lengths

7x+2x=45

Then you take 7 + 2 = 9

so is gonna be 9x = 45

then you divide both side with 9

so is gonna be x = 5

Then you take 5 multiply 7 : 2

so 7 x 5 = 35cm

2 x 5 = 10cm

Answer:

x<-10

Step-by-step explanation:

10-2.5x>35

2.5x>10-35

2.5x>-25

x>-25/2.5

x>-10

x<-10

Answer:

x < -10

Step-by-step explanation:

-2.5x > 35-10

-2.5x > 25

-2.5x > 25/-2.5

x > -10

You have to switch the sign because you divided it by negative

x<-10

Answer:

x= 75

Step-by-step explanation:

Subtract sales - expenses

200 - 12.5 = 187.5

2.5x = 187.5

Divide by 2.5 on both sides

187.5/2.5

x = 75

Answer:

y=-0.1+3

Step-by-step explanation:

Answer:

x = 1 or -5/2

Step-by-step explanation:

-2x^2 - 3x + 5 = 0

multiply all through by -1

2x^2 + 3x - 5 = 0

....... 2x^2 × 5 = 10x^2 = +5x × -2x

(2x^2 + 5x)-(2x - 5) = 0

x(2x + 5) - 1(2x + 5) = 0

x - 1 = 0 or 2x + 5 = 0

x = 1 or 2x = - 5

x = 1 or -5/2

Answer:70

Step-by-step explanation:

Answer:

A 140

Step-by-step explanation:

Mark the center of the circle as O. It's given that

∠IOJ = 70°

∠JOK = 70°

from the drawing it looks like HOI, IOJ and JOK are supplementary angles, which means that they add up to 180°

∠HOI + ∠IOJ + ∠JOK = 180°

∠HOI = 180° - ∠IOJ - ∠JOK

∠HOI = 180° - 70° - 70°

∠HOI = 40°

∠HOI and ∠KOL are cross angles, therefore ∠HOI = ∠KOL = 40°

Since ∠HOL and ∠KOL are supplementary angles

∠HOL = 180° - ∠KOL

∠HOL = 180° - 40°

∠HOL = 140°

Answer:

Answer:

The value of S is 11.

Step-by-step explanation:

Okay, I found this answer due to that A = S to the power of 2 right? Then, A = 121 m2, so S2 is 121 square rooted, meaning what number is multiplied the same to get 121? 11. And if you multiply 11 by 11, you get 121.
