Answer:

-207

Step-by-step explanation:

Using r= -3, we can substitute r in the whole equation as (-3) which gives you: ((-3)-3)^3 +(-3)^2. Now you can calculate these values in a step by step manner. (-6)^3 +9 then to -216 +9 which brings you to the answer of -207.

Answer:

225

Step-by-step explanation:

(r - 3)³ + r² if r = -3 and s = -4

(-3 - 3)^3 + (-3)^2

(-6)^3 + (9)

(-6 x -6 x -6) + 9

-216 + 9

Answer:

<J=51°

Step-by-step explanation:

3x-2+4x-9+3x-9=180

10x-20=180

10x=200

x=20

<J=3x-9=3(20)-9=60-9=51°

Answer: Angle J = 51°

Step-by-step explanation: All angles add up to 180° in a triangle, so add every angle and set it equal to 180°.

(3x - 2) + (3x - 9) + (4x - 9) = 180

Add like terms:

10x - 20 = 180

Add 20 to both sides:

10x = 200

Divide both sides by 10:

x = 20

Now, plug x into angle J:

3(20) - 9

60 - 9

51

Angle J = 51°

Hope this helps!

Answer:

B- x= 10

Step-by-step explanation:

40x=400 ->  40 x 10= 400

The value of x in the expression 40x = 400 by combining like terms would be 10. Hence, option B is true.

Given that,

The expression is,

40x = 400

Used the concept of expression by combining like terms.

Here, the expression is,

40x = 400

Divide both sides by 40,

x = 400/40

Therefore, the solution of x is,

x = 10

So, Option B is true.

The numbers between 51 and 101 and multiple of 2,8, and 16 are 80 and 96.

A numeral system is a way of writing numbers; it's a way of mathematically notating a collection of numbers by utilizing a consistent set of digits or other symbols. In several numeral systems, the same set of symbols may represent various numbers.

Given that Salma must choose a number between 55 and 101 that is a multiple of 2, 8, and 16.

To calculate the numbers between 55 and 101 and are the multiple of 2,8, and 16. Get the multiple of 16 which will be the multiple of 8 and 2.

80 and 96 is the multiple of 16 and also of 8 and 2.

80 = 8 x 10 = 80

80 = 16 x 5 = 80

80 = 40 x 2 = 80

96 = 16 x 6 = 96

96 = 48 x 2 = 96

96 = 8 x 12 = 96

Therefore, the numbers between 51 and 101 and multiples of 2,8, and 16 are 80 and 96.

Answer:

E non of the above

Step-by-step explanation:

To get the original number you multiply 88 by 4

Then you add 80, 85 and 95 and then minus it from the original number

You should end up with 352 minus 260

Therefore the answer would be 92 and not a given answer so your answer is e: none of the above

I'm guessing you're talking about the ratio,

(1.65 x 10⁸) / (2 x 10³)

You can cancel the lowest power of 10:

(1.65 x 10⁸) / (2 x 10³) = (1.65 x 10⁵) / 2

Divide 1.65 in half to get 0.825. So we have

(1.65 x 10⁸) / (2 x 10³) = 0.825 x 10⁵

Move the decimal point to the right, which involves multiplying by a factor of 10 which is taken from 10⁵, so we end up with

(1.65 x 10⁸) / (2 x 10³) = 8.25 x 10⁴

Answer:

The number of yards of silk = x = 1.5 yards

The number of yards of cotton = y = 2.75yards

Step-by-step explanation:

At a fabric store, fabrics are sold by the yard. A dressmaker spent $36.35 on 4.25 yards of silk and cotton fabrics for a dress. Silk is $16.90 per yard and cotton is $4 per yard.

Find the solution of the system of equations. Explain or show your reasoning

{x+y=4.25} ; {16.90x+4y=36.35}

Let the number of yards of silk = x

The number of yards of cotton = y

We are given the system of equations:

{x+y=4.25} ......Equation 1

x = 4.25 - y

{16.90x+4y=36.35}....... Equation 2

4.25 - y for x in Equation 2

16.90(4.25 - y) + 4y = 36.35

71.825 - 16.90y + 4y = 36.35

71.825 - 36.35 = 16.90 - 4y

35.475 = 12.90y

y = 35.475/12.90

y = 2.75 yards.

The number of yards of cotton = y

{x+y=4.25} ......Equation 1

x = 4.25 - y

x = 4.25 - 2.75

x = 1.5 yards

The number of yards of silk = x = 1.5 yards

The yards of silk bought is  1.49 yards and the yard of cotton bought is 2.76 yards.

The two equations are known as simultaneous equation. They would be solved using elimination method.

x + y  = 4.25 equation 1

16.90x + 4y = 36.25 equation 2

where:

x = yards of silk bought

y = yards of cotton bought

In order to determine the value of x, multiply equation 1 by 4.

4x + 4y = 17 equation 3

Subtract equation 3 from 2

19.25 = 12.90x

Divide both sides of the equation by 12.90

x = 1.49 yards

In order to determine the value of y, substitute for x in equation 1

1.49 + y = 4.25

y = 4.25 - 1.49

y = 2.76 yards
