Write and solve an inequality to find the values of x for which the perimeter of the rectangle is less than .

Answer:

y = 2x - 7

y = - x - 1

So 0 = - 3x + 6

So - 3x = - 6

So x = 2

And y = 2 × 2 - 7 = - 3

So (x, y) is (2,-3)

OA is correct

Answer:

8÷(x+3)

Step-by-step explanation:

it doesnt specify what number you add with 3 so you substitute it with a variable such as x.

The sum is adding so x +3 and then divide by 8

18000

Step-by-step explanation:

5000*12%= 600 600× 30= 18000 15 years semi annually = 30 x

The compound interest on $5,000 at 12% interest for 15 years compounded semi-annually is $22,243.58

To find the compound interest on $5,000 at 12% interest for 15 years compounded semi-annually, we can use the formula:

A = P(1 + r/n)^(n*t)

where:

P = principal amount = $5,000

r = annual interest rate = 12% = 0.12

n = number of times compounded in a year = 2 (compounded semi-annually)

t = time period in years = 15

A = amount after t years

Plugging in the values, we get:

A = 5000(1 + 0.12/2)^(2*15)= $27,243.58

So, the amount after 15 years is $27,243.58. To find the compound interest, we can subtract the principal amount from the amount after 15 years:

Compound interest = A - P

= $27,243.58 - $5,000

= $22,243.58

Therefore, the compound interest on $5,000 at 12% interest for 15 years compounded semi-annually is $22,243.58.

4 units x 4 is

16

Answer:

Step-by-step explanation:

First, we need to find the hypotenuse, so we need to apply the equation from the Pythagorean Theorem

A^2+B^2=C^2.

We know A^2 and B^2, so we need to substitute that into the equation

2^2+4^2=C^2

so now, simplify.

4+16=C^2

20=C^2

Square root of 20 is about 4.5

so 4.5 is the length of the sides of the square.

4.5x4.5=20.25

Answer:

f(3)=1

Step-by-step explanation:

take f(x)=2(x)-5

put a three wherever you see an x in parentheses

f(3)=2(3) - 5

simplify

f(3)=6-5

simplify

f(3)=1

answer:f(3)=1

Answer:

f(3) = 1

Step-by-step explanation:

You substitute 3 for x.

f(3) = 2(3) - 5

Multiply the 2 terms.

f(3) = 6 - 5

Subtract.

f(3) = 1

Answer:

70 or 60 is the answer

Answer:

60

Step-by-step explanation:

Given:

The distance flown was 135 km.

The average speed was 180 km/h.

To find:

The time taken by the airplane.

Solution:

We know that,

[tex]Speed=\dfrac{Distance}{Time}[/tex]

[tex]Time=\dfrac{Distance}{Speed}[/tex]

Putting Distance = 135 and Speed = 180, we get

[tex]Time=\dfrac{135}{180}[/tex]

[tex]Time=0.75[/tex]

The time taken by the airplane is 0.75 hours.

We know that,

1 hour = 60 min

0.75 hour = 0.75 × 60 min

0.75 hour = 45 min

Therefore, the time taken by the airplane is 45 min.

The cost of 1 lb of sugar candies is $1.65.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

Explanation

Given to us

weight of candy mix = 100 lb,

weight of jelly beans = 100 lb,

Cost of jelly beans = 20 cent per lb = $0.20 per lb,

Cost of candy mix = $1.36 per lb.

Total cost of candy mix:

Total cost of candy mix = weight of candy mix *  Cost of candy mix

                                       = 100 lb * $1.36

Total cost of Jelly beans:

Total cost of Jelly beans = weight of Jelly beans *  Cost of Jelly beans

                                         = 20 lb*  $0.20

Weight of Sugar candies:

weight of Sugar candies = weight of candy mix - weight of jelly bean

                                        = 80 lb

Total cost of sugar candies:

Total cost of candy mix = Total cost of jelly beans + total cost of sugar candies

100 lb * $1.36 = 20 lb*  $0.20+ 80lb*x

solving we get,

x = 1.65

Hence, the cost of 1 lb of sugar candies is $1.65.

Answer:

All the domains are x values (-8, -4, 1)

All the ranges are y values: (4, -4, -5)

Step-by-step explanation:

Area of the rectangle = L X W

Area of the rectangle = 4 X 2

Area of the rectangle = 8 inches

If the drawing is 1/5 of the actual air conditioning unit, then you multiply the reciprocal which is 5 times the area of the drawing. When you want to enlarge it has to be a whole number. When you want to reduce you multiply by a fraction.

So 8 inches X 5 = 40 inches is the actual area of the unit.

Answer:

Step-by-step explanation:

17. the sum of the lengths of any two sides of a triangle is always greater than the length of the third side

T=the third side

12+18>T

12+T>18

18+T>12

the first equation says that T<30

the second equation says that T>6

putting these together...

6<T<30
