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

The length of a room is 4 feet less than twice its width. The perimeter of the room is 58 feet. What is the length of the room?
Answer:
Length = 18
Step-by-step explanation:
Length= 2w - 4
Perimeter= 58
Perimeter= 2L + 2w
58 = 2(2w-4) + 2w
58 = 4w -8 + 2w
58 = 6w - 8
66 = 6w
11 = w
Plug in width to find the variable L
58 = 2L + 2(11)
58 = 2L + 22
36 = 2L
18 = L

Reflect Here are two paint mixtures: • $$3 cups of white and $$4 cups of blue. • $$6 cups of white and $$8 cups of blue. Both mixtures make the same color because they are in equivalent ratios. Which of these mixtures is also in an equivalent ratio? $$ white $$ blue $$ white $$ blue $$ white $$ blue $$ white $$ blue
Answer:
See Explanation
Step-by-step explanation:
Given
Mixture 1:
[tex]White = 3[/tex] [tex]Blue = 4[/tex]
Mixture 2:
[tex]White = 6[/tex] [tex]Blue = 8[/tex]
Required
Determine equivalent mixtures
First, we need to calculate the unit rate of the given mixtures using:
[tex]Rate = \frac{White}{Blue}[/tex]
For mixture 1:
[tex]Rate = \frac{3}{4} = 0.75[/tex]
For mixture 2:
[tex]Rate = \frac{6}{8} = 0.75[/tex]
So, to determine which other mixture has equivalent ratio.
All you need to do is divide the number of white cups by the number of blue cups.
Since the options are not clear enough, I'll assume the following:
[tex]White = 12[/tex] [tex]Blue =16[/tex]
The rate will be:
[tex]Rate = \frac{12}{16} = 0.75[/tex]
Any rate other than 075 is not equivalent
A company makes steel rods shaped like cylinders. Each rod has a radius of 2 centimeters and height of 70 centimeters. How much steel will the company need to make 243 rods? Use 3.14 for pie, and round your answer to one decimal
Answer:
213,645.6cm³
Step-by-step explanation:
Area of a cylinder is expressed as;
V = πr²h
r is the radius = 2cm
h is the height = 70cm
Get the volume of one rod;
V = πr²h
V = (3.14)(2)²(70)
V = (3.14)(4)(70)
V = 879.2cm³
one steel = 879.2cm³
243 rods = x
Cross multiply;
x = 879.2 * 243
x = 213,645.6
The company will need 213,645.6cm³ volume of steel to make 243 rods
