a: (3,-2)
b: (-4/3, 1)
c: (-2, 3)
d: (-8/3, -3)

Step-by-step explanation:

Answer:

4, and -9

Step-by-step explanation:

Well, to solve this problem, lets first list all the factors of -36.

-36 = 1*(-36)

-36 = 2 * (-18)

-36 = 3 * (-12)

-36 = 4 * (-9)

-36 = 6 * (-6)

-36 = 12 * (-3)

-36 = 18 * (-2)

-36 = (-36) * 1.

So, we can see that 4 + (-9) = -5.

Answer:

3,4 and 5 are correct........☺

Answer:

3,4,5

Step-by-step explanation:

To answer, we must go through all the expressions shown, solve them, and make sure that they are exactly like 3xy + 6yz.

1. We must distribute 3 to whatever is in the parentheses, but if you look, you can see that we have to multiply 3 by 6yz, which would come out to 18yz, and that is not in the original expression, so this one is FALSE

2. For this expression, we can rule it out because the first part of the expression would be 3xyz, and that is not a part of the original expression, this is one is FALSE

3. This expression, if you distribute the 3y, you get 3yx + 6zy, which is the same as the original expression, even if the variables are a bit jumbled, they all have the same value, so this one is TRUE

4. If you distribute y for this expression, you get y3x + y6z, which is the same as the original expression, because as I said before, the variables can be jumbled, but as long as all the values are there, we can safely say that this expression is TRUE

5. As you can see, this expression is the same as 4, so this one is also TRUE

y = 90°

✧My Step-by-step explanation✧:

The angle x forms a straight line with the both the 50° angle and the 40° angle:

x + 50° + 40° = 180°

x = 90°

Which means…

y = x = 90°

The number of moles is 1.4484 moles

What is one mole?

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12

The 6.022 x 10²³ number is known as the number of Avogadro or the constant of Avogadro.

(12 g C = 1 mol C atoms = 6.022 × 10²³ C atoms)

Given data ,

Grams of Hydrogen = 1.46 grams of Hydrogen

Now , 1 g of Hydrogen has 0.99212 mole

So , to calculate the number of moles in 1.46 grams of Hydrogen =
Grams of Hydrogen x 0.99212 mole

The number of moles in 1.46 grams of Hydrogen = 1.46 x 0.99212

                                                                                 = 1.4484 moles

Hence , the number of moles in 1.46g of Hydrogen is  1.4484 moles

Answer:

A: Hannah ran 0.7 miles on Tuesday

B: They ran 1.45 miles in total

Step-by-step explanation:

If you put all the fractions into decimal form it would be;

1/2 = 0.5

1/5 = 0.2

3.4 = 0.75

So, you add all of the decimals together;

0.5 + 0.2 = 0.7

0.7 + 0.75 = 1.45

Answer:

the total weight is 12,483 kilos

Step-by-step explanation:

The computation of the weight is shown below:

Wheat = 134 × 62 = 8308

Coffee = 28 × 50 = 1400

Rice 37 ×  75 = 2775

Total weight is

= 8308 + 1400 + 2775

= 12,483 kilos

Hence, the total weight is 12,483 kilos

Answer: This is easier than you thought. 3.2 is equivalent to 3.20 so the spaces between would be 3.21, 3.22, 3.23 etc. the blue dot is 3.21

Step-by-step explanation:

Answer:

-3.21

Step-by-step explanation:

You can assume that between the "-3.2" and "-3.25" has a gap of 0.5 units

Seeing as there are 5 tick marks, each one must represent 0.1 units

-3.2+(-0.1) = -3.21

Answer:

p=4.9

Step-by-step explanation:

Answer:

4.9

Step-by-step explanation:

[tex]2.5 + 3(5 - 2.1p) = - 13.37[/tex]

1) Open the brackets by multiplying 3 with each term present inside the bracket.

[tex] = > 2.5 + 15 - 6.3p = - 13.37[/tex]

2) Add the constant teems present in left-hand side.

[tex] = > 17.5 - 6.3p = - 13.37[/tex]

3) Take 17.5 to right-hand side by changing its sign from positive to negative.

[tex] = > - 6.3p = - 13.37 - 17.5[/tex]

[tex] = > - 6.3p = - 30.87[/tex]

4) Take -6.3 to right-hand side by dividing -30.87 by --6.3.

[tex] = > p = \frac{ - 30.87}{ - 6.3} = 4.9[/tex]

Answer:

x = -5

y = 20

Step-by-step explanation:

3x + y = 5

3x - 3x + y = 5 - 3x

y = 5 - 3x

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

4x + 2y = 20

4x + 2(5 - 3x) = 20

4x + 2(5) + 2(-3x) = 20

4x + 10 - 6x = 20

10 - 2x = 20

10 - 10 - 2x = 20 - 10

-2x = 10

-2x ÷ -2 = 10 ÷ -2

x = -5

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

y = 5 - 3x

y = 5 - 3(-5)

y = 5 + 15

y = 20

Step-by-step explanation:

in isoscles triangles two angles and lengths are equal .

two sides equal 3.5

so both of the angles are 55°

the sum of the angles in a triangle is 180°, so

x = 180° - 55° - 55°

x = 70° (Ans)

Answer:  The dimensions of the rectangle are 7 cm × 4 cm

Step-by-step explanation:

let,

Breadth of the rectangle (l) = x

Length of the rectangle (b) = x + 3

Area of the rectangle = 28 cm²

Area of the rectangle = l × b

⇒ (x) × (x + 3) = 28

⇒ x² + 3 x = 28

⇒ x² - 3 x - 28 = 0  

⇒ x² - 7 x + 4 x - 28 = 0

⇒ (x - 7) + 4(x - 7) = 0

⇒ (x - 7)(x + 4) = 0

⇒ x = 4

Breadth = 4 cm

Length -

⇒ 4 + 3

⇒ 7 cm
