Answer:
3x = 27
Step-by-step explanation:
Since the area of a rectangle, A = lw where l = length = x and w = width = 3 feet. So, A = 3x. Since A = 27 square feet, 27 = 3x.
So, the required equation is 3x = 27

solve this question: 2x+5is less than or equal to 3x+1,xeN.Want full working please
Answer: 4 ≥ x
Step-by-step explanation:
We want to solve the inequality
2*x + 5 ≥ 3*x + 1
We can solve it in the same way as a normal equation, we need to isolate x in one side of the equation.
I will isolate x in the right side.
2*x + 5 ≥ 3*x + 1
First, we subtract 2*x in both sides:
(2*x + 5) - 2*x ≥ 3*x + 1 - 2*x
5 ≥ x + 1
Now we subtract 1 in both sides:
5 - 1 ≥ x + 1 - 1
4 ≥ x
-3 + 42 > 3
x > 15
x < 15
x > 13
x < 13
Answer:
Where's the x?
I am assuming that the problem must be
-3 + 42 > 3x
if that is true, then
x < 13.
As this statement is, -3 + 42 > 3 is a true statement because -3 + 42 = 39, and
39 > 3 [39 is always greater than 3]
Step-by-step explanation:
Let me know if you need a step by step.
Answer:
D) x < -15
Step-by-step explanation:
-3x - 42 >3
Add 42 to each side
-3x - 42+42 >3+42
-3x > 45
Divide each side by -3. Remember to flip the inequality since we are dividing by a negative
-3x/-3 < 45/-3
x < -15

Pemba is 5 yrs older than her sister.If the sum of their ages is 35 yrs, find their ages
Answer:
Pemba is 20 and her sister 15
Step-by-step explanation:
Let the sisters age be x. As pemba is five years older, her age is x+5.
Now, the sum of their ages is 135. So, by combining the two ages we get:
=>X+(x+5)=35
x+x+5=30
2x=30
x = 15
Then, substitituing this value of x into our equations for the ages of the sisters we get
sisters age 15 years old
Pemba age (15)+5=20 years old

How much interest do you earn when you deposit $100 at 25% for 2 years?
Answer:
For simple interest: $50, for compound interest: $56.25
Step-by-step explanation:
For simple interest: 25% *100 = $25
$25*2 = $50
For compound interest:
Year 1) 100+100(.25) = 125
Year 2) 125+125(.25) = 125+31.25 = $156.25
156.25 - 100 = $56.25
Answer:
Year 1) 100+100(.25) = 125
Year 2) 125+125(.25) = 125+31.25 = $156.25
156.25 - 100 = $56.25

Answer:
9x+7y
Step-by-step explanation:
please see the image that I have attached
Hey there!
The simplified expression is 3x + 7y
To simplify this, we must add like terms. We can use the Commutative Property of addition to move the like terms together:
7x - x + 3x + 5y + 2y
Now, we can use the Associative Property to group the numbers:
(7x - x + 3x) + (5y +2y)
Now, we add the terms in the parentheses:
3x + 7y

Brad has 10 lb of oranges to make 12 bowls of fruit salad. His recipe requires 12 oz of oranges for each bowl. Does Brad have enough oranges? Please answer....
Answer: Yes, Brad has enough oranges.
Step-by-step explanation:
Given :
The orange required for one bowl = 12 oz
Thus orange required for 12 bowls = [tex]\frac{12}{1}\times 12=144oz[/tex]
Oranges available with Brad for 12 bowls = 10 lb = [tex]10\times 16=160oz[/tex]
(1lb=16oz)
As organges required is less than oranges available with Brad, thus Brad has enough oranges.

solve using elimination 10x - 9y = -8 and 2x - 8y = -14
Answer:
x = 1, y = 2
Step-by-step explanation:
Multiply 2x - 8y = -14 by 5 to get 10x - 40y = -70
Subtract (10x - 40y = -70) - (10x - 9y = -8)
Solve -31y = -62 for y
y = 2
Plug in y value to get x value
x = 1

Step-by-step explanation:
In the xy-plane, a circle with center at point (6,-8) has a radius of 20 units. If the radius of the circle is halved, which of the following points will NOT be inside the circle?
A) (-1/20 , 0)
B) (1/20 , 0)
C) (-1/10 , -6)
D) (8 , 10)
There is a circle with the center [tex](6,-8)[/tex] and radius = [tex]20[/tex] units
We have to find whether the points given in the options will not lie inside the circle if the radius of the circle is halved.
"If a point lies inside the circle, distance between the center and the given point will be less than the radius of the circle".
To find the distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
Distance = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
If a point lies inside the circle with radius 10 units, distance between the point and the center will be less than 10 units.
Option A
Distance between the points [tex](-\frac{1}{20},0)[/tex] and [tex](6, -8)[/tex]
= [tex]\sqrt{(6+\frac{1}{20})^2+(-8-0)^2}[/tex]
= [tex]\sqrt{100.6025}[/tex]
= [tex]10.03[/tex] units
Since, [tex]10.03>10[/tex] units
Therefore, [tex](-\frac{1}{20},0)[/tex] will lie outside the circle.
Option B
Distance between [tex](\frac{1}{20},0)[/tex] and [tex](6,-8)[/tex] = [tex]\sqrt{(6-\frac{1}{20})^2+(-8-0)^2}[/tex]
= [tex]\sqrt{99.4025}[/tex]
= [tex]9.97[/tex] units
Since, [tex]9.97<10[/tex] units
Therefore, [tex](\frac{1}{20},0)[/tex] will lie inside the circle.
Option C
Distance between [tex](-\frac{1}{10},-6)[/tex] and [tex](6,-8)[/tex] = [tex]\sqrt{(6+\frac{1}{10})^2+(-6+8)^2}[/tex]
= [tex]\sqrt{41.21}[/tex]
= [tex]6.42[/tex] units
Since, [tex]6.42<10[/tex] units
Therefore, [tex](-\frac{1}{10},-6)[/tex] will lie inside the circle.
Option D
Distance between [tex](8,10)[/tex] and [tex](6,-8)[/tex] = [tex]\sqrt{(8-6)^2+(10+8)^2}[/tex]
= [tex]\sqrt{328}[/tex]
= [tex]18.11[/tex] units
Since, [tex]18.11>10[/tex] units
Therefore, [tex](8, 10)[/tex] will lie outside the circle.
Now we can conclude that [tex](-\frac{1}{20},0)[/tex] and [tex](8,10)[/tex] will lie outside the circle.
Options (A) and (D) will be the correct options.

One day an e-mail is sent to 7 people. That day each person who receives the e-mail sends the email to two friends. Each friend who receives the email sends it to two more people on the following day
On the second day 28 people will have received the email.
Exponential functionsTo determine the expression that graphs this situation and determine the number of people who will have received the e-mail, the following calculation must be made:
X = Number of days the email is forwarded.7 x 2^X = People who would have received the e-mail.Thus, if the email is forwarded two days in a row, this formula operates as follows:
7x2^2 = X7 x 4 = X28 = XTherefore, on the second day 28 people will have received the email.

What is the equation in point-slope form of the line that passes through the point (-5, 6) and has a slope of 2/3
Answer:
y - 6 = ²/₃(x + 5)Step-by-step explanation:
The point-slope form of the equation of a line: y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is the point the line passing through.
m = ²/₃
(-5, 6) ⇒ x₁ = -5, y₁ = 6
So the point-slope form of the equation:
y - 6 = ²/₃(x - (-5))
or: y - 6 = ²/₃(x + 5)

The length of a rectangle is 4 cm longer than the width, The perimeter is 80 cm. Find the length and the width. Substition Method, Elimanation Method.
Answer: Length = l
Width = w
2l + 2w = 80cm
l+w = 40cm
l = w+4
w+4 + w = 40cm
2w + 4 = 40cm
2w = 36cm
w = 18cm
l = 22cm
jd3sp4o0
Step-by-step explanation:
Answer:
L = 22, W= 18
Step-by-step explanation:
You can use an equation to solve this. Since the length is 4 more than the width, you can use L = W + 4. (L = Length, W = Width). I personally like to draw a diagram to figure out the total sides. We can add up all the sides, using our equations and adding common factors. We know the perimeter is 80 cm, so we can equal it to this. Solve for W. And finally subsitute for L.
