If 20 is 40% of a value, what is that value?

2 answers:

8 0

X is the unknown value. The word "of" means to multiply. 40% in decimal form is 0.40. So "40% of a value" means "0.40x".
20=0.40x
Divide both sides by 0.40:
x=50

For two functions, f(x) and g(x), a statement is made that f(x) = g(x) at x = 5. What is definitely true about x = 5? Both f(x)

kati45 [8]

Answer: 'Both f(x) and g(x) have the same output value at x = 5' is true statement.

Step-by-step explanation:

Since, for a function f(x), x is the input value and f(x) is the output value,

Here, f(x) and g(x) are two functions,

Such that f(x) = g(x) at x = 5,

⇒ The output value of both function is equal for the input value of x.

⇒ Fourth option is the true statement.

Note : For other options, the adequate information is not given.

That's why we can not say them true.

The sum of two numbers is 54 The difference of the two numbers is 116 Find the numbers

vlada-n [284]

Answer:
85 and -31

step-by-step:
x + y = 54
x - y = 116
solve for x in first equation
x = 54 - y
sub into second equation
54 - y - y = 116
54 - 2y = 116
-2y = 62
y = -31
sub in x equation
x = 54 - (-31)
x = 85
