hayden and jamie completed 20 math problems together, jamie completed 2 more than twice the number that hayden completed. Let p

alexdok [17]

Answer:

2p+2+p = 20

Step-by-step explanation:

Let p represent the number of Math problems Hayden completed.

Let 2p+2 represent the number of Math problems Jamie completed.

Next, we have to<u><em> add them together</em></u> so that the total Math problems they completed will be equal to 20.

Let's solve.

2p+2+p = 20
3p+2 = 20
3p = 20-2
3p = 18

p = $\frac{18}{3}$

p = 6

Therefore, Hayden completed 6 Math problems.

Next, we have to get how many problems Jamie completed.

Let's solve.

2p+2 = ?
2(6)+2 = ?
12+2 = ?
14

Therefore, Jamie completed 14 Math problems.

Let's check.

2p+2+p = 20

14+6 = 20
20 = 20

It's correct!

Multiply.

Nady [450]

$\boxed{3\sqrt{22}\sqrt{58}\sqrt{18}=18\sqrt{638}}$

<h2>Explanation:</h2>

Here we have the following expression:

$3\sqrt{22}\sqrt{58}\sqrt{18}$

So we need to simplify that radical expression. By property of radicals we know that:

$\sqrt[n]{a}\sqrt[n]{b}=\sqrt[n]{ab}$

So:

$3\sqrt{22}\sqrt{58}\sqrt{18}=3\sqrt{22\times 58 \times 18}=3\sqrt{22968}$

The prime factorization of 22968 is:

$22968=2^3\cdot 3^2\cdot11\cdot 29$

Hence:

$3\sqrt{22968}=3\sqrt{2^3\cdot 3^2\cdot11\cdot 29}=3\sqrt{2^2\cdot 3^2\cdot 2\cdot 11\cdot 29}$

By property:

$\sqrt[n]{a^n}=a$

So:

$3\sqrt{2^2\cdot 3^2\cdot 2\cdot 11\cdot 29} \\ \\ 3(2)(3)\sqrt{2\cdot 11\cdot 29}=18\sqrt{638}$

Finally:

$\boxed{3\sqrt{22}\sqrt{58}\sqrt{18}=18\sqrt{638}}$

400 pounds per 340 square feet” as a rate in simplest form

Airida [17]

400lbs/340ft^2

Factor out largest common factor. LCF is the product of shared primes of the numbers prime factorization.

400=2*2*2*2*5*5, 340=2*2*5*17

So the product of the shared primes is 2*2*5=20, so divide the numerator and denominator by 40.

(400/20)lbs/(340/20)ft^2

20lbs/17ft^2 or if you prefer

(20/17)lbs/ft^2

(1 3/17)lbs/ft^2 or approximately

1.18 lbs/ft^2

Consider the line y = 3/8x + 3

Finger [1]

Answer:

Perpendicular line y = (- 8/3)x - 76/3.

Parallel line y = (3/8)x - 1

Step-by-step explanation:

y = 3/8

x + 3

1) Perpendicular line has negative reciprocal slope.

m = - 8/3

y = (- 8/3)x + b

Point (-8, - 4)

- 4 = (- 8/3)*(-8) + b

-4 - 64/3 = b

b = - 76/3

y = (- 8/3)x - 76/3

2) Parallel line has the same slope.

m = 3/8

y = (3/8)x + b

Point (-8, -4)

- 4 = (3/8)*(- 8) + b

- 4 + 3 = b

b = - 1

y = (3/8)x - 1
