Answer:

y = 28.75

x = 26.5

Step-by-step explanation:

I think the amount of the second T-shirts purchased should be 2

Let the cost of each shirt be $ x, and the cost of each sweater be $ y.

Since the cost of each shirt is $ x, the cost of 3 shirts will be $ 3x and the cost of 2 shorts will be $ 2x.

Likewise, cost of each shirt is $ x, so the cost of 2 shirts will be $ 2x and cost of 4 sweaters will be $ 4y.

Andrea was able to buy 3 shirts and 2 sweaters for $113. This means:

         Cost of 3 shirts + Cost of 2 sweaters  = 113

                 Equation 1:       3x + 2y = 113

She was able to buy p shirts and 4 sweaters for $166. This means:

                      2x + 4y = 166

Dividing both sides by 2, we get:

                  Equation 2:    x + 2y = 84                                            

Subtracting Equation 1 from Equation 2, we get:

x + 2y - (3x + 2y) = 166 - 113

x + 2y - 3x - 2y = 53

2x = 53

x = 26.5

Using the value of x, in Equation 2, we get:

26.5 + 2y = 84

2y = 57.5

y = 28.75

Since, x represents the cost of shirt, the cost of each shirt is $ 26.5.

y represents the cost of sweater, so the cost of each sweater is $ 28.75.

Answer:

69 is the answer

-4 plus 73 equals 69

Why? because you have to subtract -4 because is negative and the answer will not be correct.

Answer:

[tex]\sqrt{20}[/tex] or 4.47

Step-by-step explanation:

To find the distance between two points on a plane, you can use the distance formula: [tex]d=\sqrt{(y^{2}-y^{1})^2 + (x^{2}-x^{1})^2 }[/tex]

Plug your values in to get the distance between the two points.

[tex]d=\sqrt{(y^{2}-y^{1})^2 + (x^{2}-x^{1})^2 }[/tex]

[tex]d=\sqrt{(2-4)^2 + (7-3)^2 }[/tex]

[tex]d=\sqrt{(-2)^2 + (4)^2 }[/tex]

[tex]d=\sqrt{4 + 16 }[/tex]

[tex]d=\sqrt{20}[/tex] or 4.47

Answer:

-3/4 I think sorry if i'm wrong i can't see the rest of the graph to make sure it's totally correct.

Step-by-step explanation:

Answer:

hey where I sent I solved it in my notebook

The entire rectangle is 4 square units because the two triangles on the top put together makes the same shape as the square in the middle, which makes it 1 square unit. And the two bigger triangles on the bottom can create two squares if you break them apart and rearrange them again. So all of those shapes put together equals 4 square units.

Answer:

Y=mx+c

(4,2), (3,5)

answer is -3

Step-by-step explanation:

4=x1 and 2=y1

3=x2 and 5=y2

y2-y1/x2-x1

5-2/3-4

3/-1 or -3

since we are finding the slope,we have to minus the y2 from the y1 over the x2-x1 and we minus then simplify.

32/3125

Step-by-step explanation:

  (2/5)^5 = (2^5) / (5^5)

               = 32 /3125         means 2·2·2·2·2 = 32;   5·5·5·5·5= 3125

Answer:

[tex]a) \: 5x + 3x + 2y + 4y \\ = 8x + 6y[/tex]

[tex]b) \: 6x - 2x + 8y - 6y \\ = 4x + 2y[/tex]

Answer:

  the properties of equality tell you so

Step-by-step explanation:

A couple of properties of equality come into play here:

Each of the properties of equality tells you an operation you can perform on an equation without changing the values of the variables that satisfy that equation.

If we start with the equation ...

  5c + 4p = 18.40

and we add 11.20 to both sides, we have not changed the values of the variables that satisfy this equation. This is the addition property of equality.

  (5c +4p) +11.20 = (18.40) +11.20

The substitution property of equality says I can substitute anything for its equal. The second given equation tells me that 2c +4p = 11.20. This means I can use 2c+4p wherever 11.20 might be found without changing any variable values. In the equation we got from addition, we can now make this substitution, and we have ...

  (5c +4p) +(2c +4p) = (18.40) +(11.20)

  7c +8p = 29.60 . . . . . . . collect terms

We obtained this equation using properties of equality that guarantee solutions to these equations are not altered by the process.

_____

*Additional comment

Technically, by doing the "collect terms" step, we have made the assumption that the values of c and p that satisfy the first equation are the same as the values of c and p that satisfy the second equation. This is usually the case we're interested in.

Answer:

Area = 130 ft^2

Step-by-step explanation:

Area =length * width

Perimeter = 2(L + W)

L=3+x

W= x

Perimeter= 2(3+x+x) =2(3 +2x)=6+4x=46 so x=10

L=3 +10= 13

W= 10

Area = 13* 10 130

Answer: 27,64,72,83

Step-by-step explanation: By ascending order it is basically asking you to sort the numbers from least to greatest. So the order would be 27,64,72,and 83.

Answer:

27, 64, 72, 83

Step-by-step explanation:

27

is the least

64

is bigger than 27 yet less than 72 and 83

72

bigger than both 27 and 64 yet is less than 83

83

is last because it is the biggest one of them all

Answer: I believe it’s -5/6

Step-by-step explanation:

:)

-39 is the furthers away from 0

this is because if you draw a number line -16 would be 16 away from 0, 12 would be 12 away from zero and 7 would be 7 away from 0...

| - - - - - - - - - - - - - - - |- - - - - - | - - - - |

16 0 7 12

and -39 would be 39 digits away from 0, therefore its the furthest away from 0

Hope this helped you- have a good day bro cya)

Answer:

-39, or the absolute value of 39 is farthest from 0.

Step-by-step explanation:

-16 is 16 units from 0.

-39 is 39 units from 0.

7 is 7 units from 0.

12 is 12 units from 0.

39 > 16

39 > 7

39 > 12

Answer:

  7.84 to 8.16 ounces

Step-by-step explanation:

The difference between the actual amount in the bottle and the target amount of 8 ounces can be at most 2% of 8 ounces. That amount is ...

  0.02×8 oz = 0.16 oz

The amount in the bottle can be this much higher:

  8 + 0.16 = 8.16 . . . ounces

or, it can be that much lower:

  8 - 0.16 = 7.84 . . . ounces

The range of values the bottle could contain is from 7.84 ounces to 8.16 ounces.

Step-by-step explanation:

We observe two angles and the included side of ABC are congruent to two angles and the included side of DBE:

This is called ASA

Answer:

ASA postulate

Answer C is correct

Step-by-step explanation:

<ACB = < BED (Angle)

AC = DE (Side)

<CAB = < BED = 90° (Angle)

Therefore,

ABC triangle is congruent to DBE triangle according to ASA postulate.
