The length, l , of a rectangle is 3 cm longer than twice the width, w. The perimeter of the rectangle is 66 cm.

Which system of linear equations could be used to find the length and width of the rectangle?
A. l = 3w + 2
2l + 2w = 66

B.l = 3w + 2
l + w = 66

C.I= 2w + 3
l + w = 66

D. l = 2w + 3
2l + 2w = 66

Answers

Answer 1

Answer:

The system of linear equations that could be used to find the length and width of the rectangle will be:

l = 2w + 3 cm  

2w + 2l = 66

Hence, option D is correct.

Step-by-step explanation:

Let the width of the rectangle be = w cm

Given that the length, l, of a rectangle is 3 cm longer than twice the width, w.

Thus, the length of the rectangle be:

l = 2w + 3 cm  

We know that the perimeter of the rectangle is:

P = 2w + 2l

Given that the perimeter of the rectangle = P = 66 cm

so substitute P = 66 in P = 2w + 2l

P = 2w + 2l

66 = 2w + 2l

Therefore, the system of linear equations that could be used to find the length and width of the rectangle will be:

l = 2w + 3 cm  

2w + 2l = 66

Hence, option D is correct.

Carter has a fruit stand. In the morning, he has 25 1/2 pounds of peaches. He sells bags of peaches that each weigh 1 1/2 pounds. He will restock when he has less than 3 pounds of peaches left. Which solution represents how many bas of peaches, b, Carter will sell before he restocks?

Answers

Answer:

Carter will sell 17 bags of peaches before he restocks.

Step-by-step explanation:

Total pounds of peaches Carter have = [tex]25\frac{1}{2} = \frac{51}{2} = 25.5[/tex]

Weight of each bag = [tex]1\frac{1}{2} = \frac{3}{2} = 1.5[/tex] pound

Number of bag made = [tex]\frac{25.5}{1.5}[/tex]  = 17

The number is fully divided , it means no of peaches left = 0 < 3

So,

Carter will sell 17 bags of peaches before he restocks.

The number of bas of peaches, b, Carter will sell before he restocks is 17.

Calculation of the number of peaches:

Since he has 25 1/2 pounds of peaches. He sells bags of peaches that each weigh 1 1/2 pounds. He will restock when he has less than 3 pounds of peaches left.

So here

[tex]= 25.5 \div 1.5[/tex]

= 17

A man is 38 years old and his daughter is 14 years old. How
many years will it be before the man's age is just twice that of
his daughter?
ver:
years

Answers

Answer:

Step-by-step explanation

x+38=2(x+14)

The man is 38 and daughter is 14. They both will age in same years (x).

So, in how many years(x) will they both age until man is equal(=) to 2 times his daughters age?

x+ 38=2(x+14)

x+38=2x+ 28

10= x

In 10 years, the man will be 2twice as old as his daughter.

would it make more sense to buy two 10 inch pizzas or one 20 inch pizza? Explain your answer in detail.

Answers

I think buying two 10 inch pizzas would make more sense because you can get different topping on each. For example where I live a 10 inch pizza is 5 dollars and a 20 inch pizza is 18 dollars so 2 10 inch pizzas would cost less as well.


Hope this helps! :)

Answer:

one 20 inch pizza

Step-by-step explanation:

radius of one 10 inch pizza is 10/2 = 5

so area of one 10 inch pizza : [tex]\pi[/tex]× [tex]5^{2}[/tex] = 25 [tex]\pi[/tex]

there are 2 ; 10 inch pizza so 25 [tex]\pi[/tex]⇒[tex]50\pi[/tex]

however 20 inch pizza radius is 10

so

[tex]10^{2}[/tex]×[tex]\pi[/tex] = 100[tex]\pi[/tex]

Answers

Answer: 120, 240, 480

Step-by-step explanation:

It would appear that the numbers are increasing in multiples of 2.

15 * 2 = 30

30 * 2 = 60

The next 3 terms will therefore be:

60 * 2 = 120

120 * 2 = 240

Answer:

I believe the acceleration is 3.66666666667 m/s

Step-by-step explanation:

Acceleration formula: a = vf - vi / t

Initial velocity: 0 (I believe it was 0, as it wasn't moving in the beginning)

Final velocity: 55 m/s

Substituting values: 3.66666666667 = 55 - 0 / 15

Step-by-step explanation:

Given

As the expression is given by

[tex]3(5+4y)+8-2y[/tex]

To determine

Simplify the expression

Let us simplify the expression

[tex]3(5+4y)+8-2y[/tex]

Expand 3(5 + 4y) = 15 + 12y

[tex]3\left(5+4y\right)+8-2y=15+12y+8-2y[/tex]

grouping like terms

                              [tex]=12y-2y+15+8[/tex]

                              [tex]=10y+23[/tex]
