Step-by-step explanation:
f(x)=4x+3. f(x)=27
so 27=4x+3
27-3 =4x
24=4x
x=24/4
x=6
Answer:
48
Step-by-step explanation:
Create an equation to represent this, where x is the unknown number.
+ 6 = 18
Solve for x, by first subtracting 6 from both sides:
= 12
Multiply each side by 4:
x = 48
So, the number is 48
39 is A
40 is D
And that is my answer
N(3)-8=16
add 8 to both sides
3n=24
Divide each side by three
n=8
Answer:
4.5 inches
Step-by-step explanation:
To find the height in inches of the model, you need to change the ration into a fraction:

Then try to figure out the value of the denominator in terms of the ratio:

In this equation we need to figure out how much the denominator of the fraction is changing by, by dividing 725 by 50. Then, multiply that by one:
