Tyler thinks that the relationship between the ages of the children in Family B can be described with 2m – 2y = 10, where m is the age of the middle child and y the age of the youngest. Explain why Tyler is right.
Answer:
m - y = 5 is equivalent to 2m - 2y = 10
Step-by-step explanation:
Given
m = age of middle child
y = age of youngest child
[SEE ATTACHMENT FOR COMPLETE QUESTION]
Required
Explain why Tyler is correct
From the question, we understand that m is 5 greater than y
This can be represented as
m = 5 + y
To explain why Tyler is correct, we simply solve the above expression.
First, subtract y from both sides
m - y = 5
Multiply both sides by 2
2 * (m - y) = 2 * 5
2m - 2y = 10
This implies that m - y = 5 is equivalent to 2m - 2y = 10
And that means, Tyler conclusion is correct
Walkway over the hudson, a bridge that crosses the hudson river in poughkeepsie, is 2.063 kilograms long. Anping bridge, which was built in china 850 years ago, is 2.07 kilograms long. what is the total span of both bridges.
Answer: 4.133 kilometers
Step-by-step explanation:
From the question, we are informed that walkway over the hudson, a bridge that crosses the hudson river in poughkeepsie, is 2.063 kilograms long and that Anping bridge, which was built in china 850 years ago, is 2.07 kilograms long.
The total span of both bridges will be the addition of both walkway. This will be:
= 2.063 kilometers + 2.07 kilometers
= 4.133 kilometers

In a sprint to the finish, a professional cyclist travels 380 meters in 20 seconds. At that rate, how many meters will the cyclist travel in 7 seconds?
Answer:
133m
Step-by-step explanation:
Rate can be defined as the measure of a quantity with time
Rate the professional cyclist travels =380/20
To know the rate rate, in meters will the cyclist travel in 7 seconds then we equate the rate above as
380/20= x/7
Cross multiply
380×7=20X
2660= 20x
X=133m
Hence, the rate rate, in meters will the cyclist travel in 7 seconds is 133m

5. Given that 2x+329, the range of values of x is
(1 Point)
Answer:
The range of 2x+329:
[tex]\mathrm{Range\:of\:}2x+329:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<f\left(x\right)<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]
Step-by-step explanation:
Given the expression
[tex]2x+329[/tex]
We know that range is termed as the set of values of the dependent variable for which a function is defined.
We also know that the range of polynomials with odd degree is all the real numbers.i.e. [tex]-\infty \:<f\left(x\right)<\infty \:[/tex]
The given expression is a polynomial with an odd degree. Hence, the range of this expression will be all the real numbers.
Thus, the range of 2x+329:
[tex]\mathrm{Range\:of\:}2x+329:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<f\left(x\right)<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]
Morgan and Kira have a number of jelly beans in a ratio 5:3. If Morgan and Kira have a total of 64 jelly beans, how many does Kira have? What are we comparing
Answer:
Kira has 40 Jelly beans
Step-by-step explanation:
Morgan and Kira have a number of jelly beans in a ratio 5:3.
The ratio is
Morgan : Kira
5:3
The total proportion is= 5 + 3 = 8
Total number of Jelly beans that they have together is = 64 jelly beans
Hence, the number of Jellybeans that Kira has is calculated as:
5/8 × 64 jelly beans
= 40 jelly beans.
Kira has 40 Jelly beans

Answer:
y=2x+4
Step-by-step explanation:
2 is the slope, you can see that with rise over run. 4 is the y intercept
Answer:
y=2x+4
Step-by-step explanation:
Look at the y-axis if the point that touches the y-axis is 4
Then the slope is 2
you go down 2 which is -2 (Since down is negative)
and you go left 1 which is -1 (Since left is negative)
now the equation looks like this:
y=-2/-1x+4
Simplify: (negative and negative cancel each other out making it positive)
y=2x+5
The fuel tank of a certain airplane can hold up to 300 gallons of fuel. Let Wbe the total weight(in pounds) Let F be the total amount of fuel in this tank ( in gallons) Suppose that W = 6F +4000 gives W as a function of F
Answer:
Range of weight = [4,000 , 5,800]
Step-by-step explanation:
Given:
Function W = 6F +4000
Full amount of fuel = 300 gallons
No amount of fuel = 0 gallons
Find:
Range of weight
Computation:
Domain : amount of fuel = [0 , 300]
If F = 0
W = 6F + 4,000
W = 6(0) + 4,000
W = 4,000
If F = 300
W = 6F + 4,000
W = 6(300) + 4,000
W = 5,800
Range of weight = [4,000 , 5,800]
