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

Priya has a recipe for banana bread. She uses 7/1/2 cups of flour to make 3 loaves of banana bread. Andre will follow the same recipe. He will make b loaves of banana bread using f cups of flour. Which of these equations represents the relationship between b and f?
Answer:
5b=2f
Step-by-step explanation:
Priya uses [tex]7\dfrac{1}{2}[/tex] cups of floor to make 3 loaves of banana bread.
Andre will follow the same recipe. He will make b loaves of banana bread using f cups of flour.
To find the relation between b and f, the steps are as follows :
[tex]\dfrac{\text{cups of flour}}{\text{loaves of banana bread}}=\dfrac{7 \dfrac{1}{2}}{3}\\\\=\dfrac{\dfrac{15}{2}}{3}\\\\=\dfrac{15}{2}\times \dfrac{1}{3}\\\\=\dfrac{5}{2}[/tex]
It means,
[tex]\dfrac{f}{b}=\dfrac{5}{2}\\\\5b=2f[/tex]
So, the relationship between b and f is "5b=2f".
Answer:
5b = 12f

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

Answer:
b = -12
Step-by-step explanation:
First isolate b by subtracting 2 from both sides: b/4 = -3
then multiply both sides by 4 to find b: b = -12
Answer:
b= -12
Step-by-step explanation:
b/4 + 2 = -1
Subtract 2 from both sides
b/4 = -3
Multiply both sides by 4
b= -12

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
A peqch pie is made with 13 peaches, which are evenly distributed throughout the pie. If Joe ate one slice that contained exactly 5 peaches, what was the angle measure of the slice to the nearest tenth of a degree?
Answer:
138.5°
Step-by-step explanation:
Since the peach pie is a circle, we have a total angle of 360°.
We need to determine what fraction of the total pie of 13 peaches is the 5 peaches contained in Joe's slice.
This is number of peaches in Joe's slice/total number of peaches in pie = 5/13. To find the angle Joe's slice measures, we multiply 5/13 by 360°.
So, 5/13 × 360°
= 0.3846 × 360°
= 138.46°
≅ 138.5° to the nearest tenth of a degree
