Noah is right because 75% of $10 would be 7.5 and 25% of $30 is 7.5. This would mean that they both have equal amounts of money
Answer: 15c
Step-by-step explanation:
When you come across any question that mentions [the product of a and b] means a × b
- the product of 6 and 7 is 42, 6 × 7=42
- the product of x and y is xy, x × y=xy
<u>Solve:</u>
The product of 15 and c
<h2>15 × c=15c</h2>
Answer: I am going tot give you an example for this because I don’t like giving straight up answers ok?
Step-by-step explanation:
Lets use this conversion factor:
4 inches = 1 year
Let's find the year at 5 feet (60 inches) using the conversion factor. Set up a proportion.
4 / 60 = 1 / x
Cross multiply.
4x = 60
x = 15
At 15 years, the height is 60 inches.
We can use these as points.
x = time in years
y = height in inches
Point 1 = (1, 4)
Point 2 = (15, 60)
By looking at the points, we know that as the x values increase, so does the y values. Now the relation between the x and y values of each point is that y is 4 times as that of x. Therefore, we can establish an equation.
y = 4x
This will be the model to use to find the height in 30 years.
Answer:
Since the above triangle is Iscocleles we can make our equation-
5x - 8 = 2x + 7
5x - 2x = 8 + 7
3x = 15
x = 5
Hope it helps
Answer:(x-5)/8
Step-by-step explanation:
f(x)=8x+5
let f(x)-1=y
y=8x+5
interchanging x and y
x=8y+5
y=(x-5)/8
Therfore f(x)-1=(x-5)/8
