Answer:

Not the solution tp the system because the ordered pair should be true for both equations. However the last equation is not true.

Step-by-step explanation:

(-1,-2) is the solution of the system. x + y =-3 and 2x - y = -4*

x + y =-3 :

(-1)+ (-2) = -3

-1-2 =-2   -3=-3

2x - y = -4:

2(-1)-(-2)=-4

(-2) -(-2)= -4

0=-4

Answer:

30feet= 91.5 centimeters

The total of cm in the 1 yard based upon  30.5 centimeters in a foot will be 91.5 centimeters.

Multiplication is the general procedure in mathematics in which we multiply two or more numbers to each other to find a new multiplied number.

In another word, multiplication is nothing but changing one value by-product of another value

Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.

Given that

1 feet = 30.5 centimeters

Given that

1 yard = 3 feet

Hence 1 yard = 3 × 30.5 centimeter.

1 yard = 91.5 centimeters hence in 1 yard there will be 91.5 centimeters

Answer:

y = - 3x - 2

Step-by-step explanation:

The function is linear and can be expressed in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (- 1, 1) ← 2 ordered pairs from the table

m = [tex]\frac{1-4}{-1-(-2)}[/tex] = [tex]\frac{-3}{-1+2}[/tex] = [tex]\frac{-3}{1}[/tex] = - 3 , then

y = - 3x + c

To find c substitute any ordered pair into the equation

using (0, - 2 ) , then

- 2 = - 3(0) + c = 0 + c ⇒ c = - 2

y = - 3x - 2 ← function rule

y = - 3x - 2

Answer:

1.85 grams

Step-by-step explanation:

1 milligram is equal to 0.01 gram

so 1850 should be equal to 1.85 grams

Answer: 1.85 grams of potassium.

Step-by-step explanation: Since 1,000 milligrams is equal to 1 gram, you have to divide 1850 by 1000. The results will be 1.85.

Answer:

8.69 m

Step-by-step explanation:

We have to use the Pythagorean theorem here

Statue is 3.4 tall, that's one leg of the right traingle

Braden is 8 meters away, that's the longer leg of the right triangle

the hypotenuse would be the distance between Braden's head and the top of the statue (let's assume it is X )

x^2 = 3.4^2 + 8^2 = 11.56 + 64 = 75.56

x = 8.69

Exponent properties help us to simplify the powers of expressions.  The quotient of the given expression [tex]\dfrac{6 - 3(\sqrt[3]{6})}{\sqrt[3]{9}}[/tex] is (2∛3 - ∛18).

[tex]{a^m} \cdot {a^n} = a^{(m+n)}\\\\\dfrac{a^m}{a^n} = a^{(m-n)}\\\\\sqrt[m]{a^n} = a^{\frac{n}{m}}\\\\(a^m)^n = a^{m\times n}\\\\(m\times n)^a = m^a\times n^a\\\\[/tex]

Given to us

[tex]\dfrac{6 - 3(\sqrt[3]{6})}{\sqrt[3]{9}}[/tex]

We will solve the problem using the basic exponential properties,

[tex]\dfrac{6 - 3(\sqrt[3]{6})}{\sqrt[3]{9}}\\\\ = \dfrac{6}{\sqrt[3]{9}} - \dfrac{3(\sqrt[3]{6})}{\sqrt[3]{9}}\\\\ = (6\cdot 3^{-\frac{2}{3}}) - [3 \cdot (2 \cdot 3)^{-\frac{2}{3}}3^{-\frac{2}{3}}]\\\\= (2 \cdot 3 \cdot 3^{-\frac{2}{3}}) - [3 \cdot 2^{-\frac{2}{3}} \cdot 3^{-\frac{2}{3}}3^{-\frac{2}{3}}]\\\\[/tex]

[tex]= [2 \cdot 3^{(1-\frac{2}{3})}] - [2^{\frac{1}{3}}\cdot 3^{(1+\frac{1}{3} - \frac{2}{3})}]\\\\= [2 \cdot 3^{(\frac{1}{3})}] - [2^{\frac{1}{3}}\cdot 3^{(\frac{2}{3})}]\\\\= 2\sqrt[3]{3} - \sqrt[3]{2}\sqrt[3]{9}\\\\=2\sqrt[3]{3} - \sqrt[3]{18}[/tex]

Hence, the quotient of the given expression [tex]\dfrac{6 - 3(\sqrt[3]{6})}{\sqrt[3]{9}}[/tex] is (2∛3 - ∛18).

Step-by-step explanation:

Well you can make a proportion out of this question.
so lets do faulty/total

Since x/100 is basically finding the percent since percent means out of a hundred.

Cross multiply to solve.

3(7x + 1)

3 . 7x = 21x

3.1 = 3

3(7x + 1 ) = 21x + 3

The equivalent expression with the fewest symbols possible is 21x+ 3.

The distributive Property states that it is necessary to multiply each of the two numbers by the factor before performing the addition operation when a factor is multiplied by the sum or addition of two terms.

we have,

3 x (7x+ 1)

By Distributive property we know

a x( b+ c) = a x b + a xc

ax (b-c) = a x b - a x c

So, 3 (7x + 1 )

= 3 (7x)+ 3(1)

= 21x + 3

Hi there!

The solution to this system of equations is the point where the graphs of the equations intersect.

That point only will make both equations true.

So, where do these graphs meet?

First, look at the x-coordinate. It's -6.

Now, look at the y-coordinate. It's -2.

Thus, the answer is

(-6, -2)

Hope it helps!

Answer:

3500[tex]\pi[/tex] = 10995.57 in³ (nearest hundredth)

Step-by-step explanation:

area of a circle = [tex]\pi r^2[/tex]

Answer:

Step-by-step explanation:

6. x + 21 = 56

→ x = 56 – 21

→ x = 35

7. n – 13 = 8

→ n = 8 + 13

→ n = 21

8. w – 7 =41

→ w = 41 + 7

→ w = 48

9. b + 22 = 89

→ b = 89 – 22

→ b = 67

10. z – 53 = 26

→ z = 26 + 53
