Consider this system of equations.
p = 2n
p - 5 = 1.5n
What value of n makes the system of equations true.
Explain how you got your answer.

Answers

Answer 1

Answer: n=10

Step-by-step explanation:

p=2n

p-5=1.5n

- replace 2n in the 2nd equation for p

2n-5=1.5n

2n=1.5n=5

2n-1.5n=5

0.5n=5

n=10

Answer: A. 9.4 units

Step-by-step explanation:

       We could use the distance formula, but this problem asks us to use the Pythagorean theorem. This means we will "create" a right triangle and solve for the hypotenuse.

       [1] First, we need to draw our triangle.

-> Please see attached.

       [2] Now, we will count the length of the sides for the formula.

-> Please see attached.

       [3] Lastly, we can use the Pythagorean theorem to solve for the missing side which also known as the hypotenuse. In this case, it is from point R to point S

a² + b² = c²

5² + 8² = c²

25 + 64 = c²

89 = c²

[tex]\sqrt{89}[/tex] = c

c ≈ 9.43

-> Which becomes 9.4 when rounded to the tenths place.

Answer:

15

Step-by-step explanation:

(1/6) of 18

= (1/6)×18

= 3

18-3

=15

Answer:

15

Step-by-step explanation:

We have been told:

Alex made 18 free throws Quinn made 1/6 less than that

Therefore, to find the number of throws Quinn made, we need to find 1/6 of 18, then subtract this from 18 (the number of throws Alex made).

[tex]\begin{aligned}\sf \dfrac16\:of\:18 &=\sf \dfrac16 \times 18\\\\ & = \sf \dfrac{1 \times 18}{6}\\\\ & = \sf\dfrac{18}{6}\\\\ & =\sf18 \div 6\\\\ & =\sf3\end{aligned}[/tex]

Now we have calculated 1/6 of 18, we can subtract it from 18 to find the number of throws Quinn made:

⇒ Number of throws Quinn made = 18 - 3 = 15

which is largest 3.3 times 10^5 or 3.1 times 10^5

Answers

Answer: 3.3 times 10^5 is bigger

Step-by-step explanation: 10^5= 10*10*10*10*10=100,000.

so 100,000 multiplied by 3.3 = 330,000

or 3.1 multiplied by 100,000 = 310,000 so it's obvious that 330,000 is bigger.

3.3 x 10^5 = 50.3 and 3.1 x 10^5 = 50.1

Answer:

x = -40

Step-by-step explanation:

Rewrite "(x - 4)/4" in a different way:

⇒ 8 + x/2 = (x - 4)/4 - 1

⇒ 8 + x/2 = x/4 - 4/4 - 1

Simplify the R.H.S:

⇒ 8 + x/2 = x/4 - 1 - 1

⇒ 8 + x/2 = x/4 - 2

Add 2 both sides and subtract x/2 both sides:

⇒ 8 + x/2 = x/4 - 2

⇒ 8 + 2 = x/4 - x/2

⇒ 10 = x/4 - 2x/4

Simplify the R.H.S:

⇒ 10 = x/4 - 2x/4

⇒ 10 = -x/4

Use cross multiplication:

⇒ 10 × 4 = -x

Vincent plans to save of ⅔ his earnings each week for 16 weeks. He earns approximately $180 per week. About how much will Vincent have saved from earnings at the end of 12 weeks?


Please no links

Answers

Answer:

$1440

Step-by-step explanation:

2/3 earings each week

He gets approximately 180 per week

2/3 of 180 is 120

120*12=1440

He would have saved $1440.

         

$180 divided by 3 is $60 which is 1/3 of $180
To get 2/3 of $180, you’ll do
$60x2=$120 which is 2/3 of $180
Now, $120x12weeks= $1,440
Answer- Vincent will have $1,440 at the end of 12 weeks.

79 + 80 + 82 + 84 + 87 = 412

412/5 = 82.4

|79 - 82.4| = 3.4

|80 - 82.4| = 2.4

|82 - 82.4| = 0.4

|84 - 82.4| = 2.4

|87 - 82.4| = 4.6

3.4 + 2.4 + 0.4 + 2.4 + 4.6 = 13.2
