Explain how to use properties to prove d + (8d + 1) + 7 is equivalent to 8 + 9d.
Answer: See explanation
Step-by-step explanation:
From the question, we are told to prove that prove d + (8d + 1) + 7 is equivalent to 8 + 9d.
= d + (8d + 1) + 7
First we need to open the bracket. This will be:
= d + (8d + 1) + 7
= d + 8d + 1 + 7
Collect like terms
= 9d + 8
= 8 + 9d
Therefore, we have proven that + (8d + 1) + 7 is equivalent to 8 + 9d.

Will weighs three times as much as Brenda. Together, they weigh 240
pounds. How much does each of them weigh
let
brenda: b
will: 3b
b + 3b = 240
4b = 240
b = 60 lbs (BRENDA)
3b = will
3 (60) = will
180 = WILL
The solution is
The weight of Brenda = 60 pounds
The weight of Will = 180 pounds
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the weight of Brenda be = x
Let the weight of Will be = y
Now , Will weighs three times as much as Brenda
Substituting the values in the equation , we get
y = 3x be equation (1)
And , the weight of Will + weight of Brenda = 240 pounds
So , x + y = 240 be equation (2)
Substituting the value of y from equation (1) in equation (2) , we get
x + 3x = 240
On simplifying the equation , we get
4x = 240
Divide by 4 on both sides of the equation , we get
x = 60 pounds
So , the weight of Brenda is 60 pounds
Substitute the value of x in equation (1) , we get
y = 3x
y = 3 x 60
y = 180 pounds
So , the weight of Will is 180 pounds
Hence , the weight of Brenda is 60 pounds and weight of Will is 180 pounds

Step-by-step explanation:
Basically we need to find the hypotenuse of the triangle, or the longest side.
The formula for finding the hypotenuse of a triangle is: c = √(a² + b²)
First we need to multiply 14.3 and 17.1 to the second power.
14.30 × 14.30 = 204.49
17.10 × 17.10 = 292.41
Now we add our two sums.
204.49 + 292.41 = 496.90
Now we need to find the square root of 496.90, which is 22.2912539.
Rounded to the nearest DP(Decimal point), it's 22.30
Which is the solution for ln(3x - 5) = ln(11) + ln(2) ?
Answer:
B: x=9
Step-by-step explanation:
You have to use the property of logarithms
that says ln A + ln B = ln AB. So here we have
ln (3x - 5) = ln 11 + ln 2 = ln 22
Therefore 3x - 5 = 22, from which x = 9

Step-by-step explanation:
Sandy has 27 roses, 9 daisies, and 45 tulips. She wants to arrange all the flowers in bouquets. Each bouquet has the same number of flowers and the same type of flower. What is the greatest number of flowers that could be in a bouquet?
We solve the above question using Greatest Common Factor method.
We find the factors of 27, 9 and 45
The greatest common factor is the highest factor common to these 3 number
Hence:
The factors of 9 are: 1, 3, 9
The factors of 27 are: 1, 3, 9, 27
The factors of 45 are: 1, 3, 5, 9, 15, 45
Then the greatest common factor is 9.
Therefore, the greatest number of flowers that could be in a bouquet is 9 flowers
Each bouquet would contain
For 27 roses = 27/9 bouquet = 3 roses
For 9 daisies = 9 daisies/9 bouquet = 1 daisies
For 45 tulips = 45 tulips/9 bouquet = 5 tulips

Mike drove 100 miles in a rental car and was charged $58.00. Jane rented the same car after Mike had rented it and was charged $65.00 for 170 miles. Write an equation to represent y, the total rental cost, in terms of x, the number of miles driven.
Answer:
y= 48 + 0.1x
x= miles driven
Step-by-step explanation:
We need to calculate the fixed and variable cost (per mile) of renting a car. To do that, we will use the high-low method:
Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)
Variable cost per unit= (65 - 58) / (170 - 100)
Variable cost per unit= $0.1 per mile
Fixed costs= Highest activity cost - (Variable cost per unit * HAU)
Fixed costs= 65 - (0.1*170)
Fixed costs= $48
Fixed costs= LAC - (Variable cost per unit* LAU)
Fixed costs= 58 - (0.1*100)
Fixed costs= $48
y= 48 + 0.1x
x= miles driven

A long string with a balloon at the end was tied to the ground. After a breeze came up, the balloon was 55 feet to the right of where it was tied and 30 feet above the ground, as shown in the figure below. What is the slope of the line between the balloon and the point where it was tied?
Answer:
The slope is 0.55
Step-by-step explanation:
Right Triangles
The string, the ground, and the height of the balloon form a right triangle where the trigonometric ratios are satisfied.
The image below shows the geometric construction. We are required to find the slope the string forms with the ground.
It can be found by using the tangent ratio:
[tex]\displaystyle \tan\theta=\frac{y}{x}[/tex]
Substituting y=30 and x=55
[tex]\displaystyle \tan\theta=\frac{30}{55}[/tex]
[tex]\displaystyle \tan\theta=0.55[/tex]
The slope is 0.55
