Solve equation 3(n - 5) = 7 - 2(n + 1)

AlladinOne [14]

Answer:

n= 4

Step-by-step explanation:

3 multiplied by n is 3n.

3 multiplied by -5 is -15.

so 3n-15= 7-2(n+1)

7-2(n+1) is -2 multiplied by n is -2n and -2 multiplied by 1 is -2.

3n-15=7-2n-2

then move the variables to one side and numbers to the one side.

3n+2n=15+7-2

*If you are moving across the equation the symbols change. Like negative to positive. Division to multiplication.

so 5n=22-2

5n=20

5 multiplied by 4 is 20 so n is going to be 4.

The sum of the lengths of the two bases of a trapezoid is 22 cm and its area is 66 cm2.

ludmilkaskok [199]

Answer:

h = 6 cm

Step-by-step explanation:

Given that,

The area of a trapezoid, A = 66 cm²

The sum of the lengths of the two bases of a trapezoid is 22 cm.

We need to find the height of the trapezoid.

The area of a trapezium is given by :

$A=\dfrac{1}{2}\times (\text{sum of parallel sides})\times \text{height}$

Substitute the values,

$h=\dfrac{2A}{\text{sum of parallel sides}}\\\\h=\dfrac{2\times 66}{22}\\\\h=6\ cm$

So, the height of the trapezoid 6 cm.

Three cards are randomly selected from a standard 52-card deck, one at a time, with each card re- placed in the deck before the

hammer [34]

Answer:

$\frac{1}{4}$

Step-by-step explanation:

Three cards are randomly selected from a standard 52-card deck.

Number of heart cards in a deck = 13

Each card replaced in the deck before the next one is picked.

Probability of first card is heart = $P_{1}=\frac{13}{52}$

After replacement, the probability of second card is heart = $P_{2}=\frac{13}{52}$

after replacement, the probability of third card is heart = $P_{3}=\frac{13}{52}$

P = $\frac{13}{52}$ × $\frac{13}{52}$ × $\frac{13}{52}$

= $\frac{39}{156}$

= $\frac{1}{4}$

The probability of all three cards are hearts is $\frac{1}{4}$

Solve for x: 12(x-2)<24

il63 [147K]

<span>12(x-2)<24
Multiply the number outside the parenthesis with the numbers inside the parenthesis
12x-24<24
Add 24 to both sides
12x<48
Divide both sides by 12 so that x is the only thing remaining on the left side is the x variable.
Final Answer: x<4</span>
