Answer:

theresa needs 48 pieces and samuel needs 24 pieces

Step-by-step explanation:

the exact answers are 24.07692307692308

48.15384615384615

Answer with step-by-step explanation:

Yes, it is possible to have more that one (x,y) pair because of the distributive property.

6x + 4y = 34. If this is the case, we have to find 2 numbers that sum up to 34.

5x - 27 = 15. If we are going to calculate this equation, you need to reverse the equation. 15 + 27 = 42 = 5x. If 42 = 5x, we have to divide 42 by 5, which is 8.4

Answer:

1049.75

Step-by-step explanation:

take 15% off of 1235 or 1235 divided by 15%

The discount will be 15% and the discounted price is $1049. 75

A discount is a price reduction you offer a customer. There are also other methods that you can use to attract customers.

Given:

price for 35 uniforms = 1235

as, there is 15% discount for the items 25- 49 items.

So, there is 15% discount for 35 uniforms

Thus, the discounted price is

=1235 (1- 15%)

=1235 (1- 0.15)

=1235 x 0.85

= $1049. 75

Hence, the discounted price is $1049. 75.

Answer:

x = 2

y = -3

Step-by-step explanation:

The given equation is,

22(x + yi) + (28 + 4i) = 72 - 62i

By solving this equation further,

22x + 22yi + 28 + 4i = 72 - 62i

(22x + 28) + (22y + 4)i = 72 - 62i

Now both the sides of the equation is in the form of complex number,

By comparing real and imaginary parts given on both the sides,

22x + 28 = 72

22x = 72 - 28

22x = 44

x = 2

22y + 4 = -62

22y = -62 - 4

22y = -66

y = -3

Therefore, x = 2 and y = -3 are the values for which the given equation is true.

The given estimate is not correct. The correct estimate will be 4.36 × [tex]10^{-3}[/tex].

It is given that Kim writes an estimate for number 0.00436 as 4 × 10 ³.

We have to find whether it is correct or not and why ?

What do you mean by decimal fraction ?

A decimal fraction is a number in which the denominator is a multiple of 10 i.e., 10, 100, 1000. etc.

As per the question ;

The decimal number given is 0.00436.

To represent the number in the form of power of 10 , we need to move the decimal 3 places towards right.

and

We know if we move decimal 3 places towards right we need to multiply the resulted number by 10 to the power -3 , i.e., [tex]10^{-3}[/tex]

So,

The correct estimate will be ;

= 4.36 × [tex]10^{-3}[/tex]

Thus , the given estimate is not correct. The correct estimate will be 4.36 × [tex]10^{-3}[/tex].

Answer:

X=9

Step-by-step explanation:

We want to first understand that a triangle will always be 180°. Next, we want to look at both where 25° and 12x-3 are. If we look closely we can see that they are the vertical angles of the interior angles of the triangle. To solve this algebraically we have to basically add all the angles (including 12x-3) to solve for x.

Adding all the angles together would look like this: 25+50+12x-3. Next, add up all like terms to get 12x+72=180. You want to get x by itself by subtracting by 72 on both sides to get 12x=108. Isolate x by dividing by 12 on each side which results in x=9

Step-by-step explanation:

The square root of 135 is 11.61895. Rounded to the nearest whole number (integer), it is 12.

Answer:

x ≈ 5.9

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 2.7² = 6.5²

x² + 7.29 = 42.25 ( subtract 7.29 from both sides )

x² = 34.96 ( take the square root of both sides )

x = [tex]\sqrt{34.96}[/tex] ≈ 5.9 ( to 1 dec. place )

Answer:

b has to be 2

If A equals 16 after multiplying b and h together and h is 8 then b would be 2 since 8 times 2 is 16.    

Answer:

(2, -1)

Step-by-step explanation:

We can subtract x from both sides from the first equation, then multiply the first equation by 4, so it's easier to solve later:

-4x+8y = -16

4x+3y = 5

Then, we can add the 2 equations, so the x cancels out:

11y = -11

y=-1

Now, we can plug y as -1 to any of the equations above:

4x+3*(-1)=5

4x=8

x=2

Therefore, the solution to these 2 equations are (2, -1)

The value of the variables 'x' and 'y' will be 2 and negative 1, respectively.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The system of equations is given below.

x = 2y + 4             ...1

4x + 3y = 5          ...2

From equations 1 and 2, then we have

4(2y + 4) + 3y = 5

8y + 16 + 3y = 5

11y = - 11

y = -1

Then the value of 'x' is given as,

x = 2 (-1) + 4

x = - 2 + 4

x = 2

The value of the variables 'x' and 'y' will be 2 and negative 1, respectively.
