Answer:

R = 4

s = -3

Step-by-step explanation:

r + 4s = -8

3r + 2s = 6

there are several ways to solve this system but i chose the elimination method and multiplied the second equation by -2 to get:

  -6r - 4s = -12 and added it to the first equation

+ 1r + 4s =  -8

 -5r = -20

   r = 4

plug in to find 's':  4 + 4s = -8

                              4s = -12

                               s = -3

Answer:

We found the factors and prime factorization of 7 and 14. The biggest common factor number is the GCF number. So the greatest common factor 7 and 14 is 7.

Step-by-step explanation:

The value of the Expression 7+ 14  using the GCF is 21.

The largest factor that splits both numbers is said to be the greatest common factor. List the prime factors of each integer before calculating the greatest common factor. One 2 and one 3 are shared by those aged 18 and 24. The GCF of 18 and 24 is 2 * 3 = 6, which we multiply to obtain.

Given:

We have to add 7  + 14

Factorise the terms separately

7 = 7 x 1

14 = 7 x 2

So, the Greatest Common Factor is 7.

Thus, 7+ 14 = 7(1+ 2) = 7 x 3= 21

Answer: f(2)=1

Step-by-step explanation:

This is a function-related problem. In order to solve f(2), you need to substitute the value into the original function.

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

f(x)=5x⁵-3x⁴- 17x³-4x²+10x+21

f(2)=5(2)⁵-3(2)⁴- 17(2)³-4(2)²+10(2)+21

f(2)=160-48-136-16+20+21

f(2)=1

Answer:

c (6)

Step-by-step explanation:

by the corresponding angles postulate, the angle above 20x-5 will be 65°.

20x - 5 + 65 = 180 they are supplementary angles (angles that add up to 180°)

20x + 60 = 180

20x = 120

x = 6

Answer:

16 1/2 gallons of water.

Step-by-step explanation:

Since 4 bottles can hold 8 gallons, and you need to know how much 10 can hold, you can multiply 4 and 8 times 2 so you get 8 and 16, and then if you choose 10 instead of 8 instead you would get the result of 10 bottles being able to hold 16 1/2 gallons of water.

Step-by-step explanation:

The nearest hundred thousand is the first 5

In rounding when something is 4 or lower it becomes a zero and if it is 5 or higher it is goes up to the next number for example if it is rounded to the nearest ten, and the number is 338, it would be 340

Answer: 6(u-2)+2=6u-10

Step-by-step explanation:

Then, any value of u makes the equation true.

The other side of this equation 6 (u-2) + 2 is 6u - 10 and is true for all values of u.

An assertion that two mathematical expressions have equal values is known as an equation. An equation simply states that two things are equal. The equal to sign, or "=," is used to indicate it.

Given:

6 (u-2) + 2

Simplify the above expression as shown below,

6 × u - 6 × 2 + 2  (Use distributive property)

6u - 12 + 2    (Add constant terms)

6u - 10

Thus, 6 (u-2) + 2  = 6u - 10

Answer:

100% is 9, 55% is 4.95, 75% is 6.75.

Step-by-step explanation:

Suppose that 100% were [tex]x[/tex]. Then 30% is 27, so [tex]0.3x=27[/tex] and we can divide both sides by 0.3 to see that [tex]x=\frac{27}{0.3}=\frac{27}{\frac{3}{10}} = \frac{27\cdot 10}{3} = 90.[/tex] So 55% is [tex]0.55x = 0.55 \cdot 9 = 4.95[/tex] and 75% is [tex]0.75x = 0.75\cdot 9=6.75[/tex]. (Note that we can divide the value of a percentage by 100 - the same as moving the comma by two places to the left - to get the decimal value.)
