Answer:
$13.75 per gallon
Step-by-step explanation:
To solve for any unit rate you use
[tex]\frac{1}{x} =\frac{5}{68.75}[/tex]
Cross multiply.
So 68.75 = 5x
Divide both sides by 5 to get x alone.
13.75 = x
Therefore 1 gallon equals $13.75
If h(x) = 5 + x and (x) = 5. which expression is equivalent to (k-1)(o)? (5+) 1 (5+) 5+ 5+ (5 + x)
(5+x)/x
K*H = 1/x(5+x) or (5+x)1/x which = (5+x)/x because (5+x)1/x = [(5+x)/1] * [1/x] and anything multiplied by one is equal to itself.
If h(x) = 5 + x and k(x) = 5 then the expression which is equivalent to (koh)(x) is 25+5x
What is a function?A relation is a function if it has only One y-value for each x-value.
The given functions are h(x) = 5 + x and k(x) = 5x
We have to find the expression which is equivalent to (koh)(x)
(koh)(x) = k(h(x))
=k(5+x)
Now we have to plug in 5+x in the function k(x)
k(5+x)=5(5+x)
=25+5x
Hence, if h(x) = 5 + x and k(x) = 5 then the expression which is equivalent to (koh)(x) is 25+5x

Mai and Jada are both running on a treadmill. Mai travels 5 miles in 15 minutes. Jada travels 4 miles in 14 minutes. Who ran at a faster rate? Show and explain your reasoning
Answer:
Mai
Step-by-step explanation:
To find the rate, you must determine who is going faster per minute. To do this, you must divide the total number of miles by the total number of minutes.
Mai: 5 miles / 15 minutes = 1/3 miles per minute
Jada: 4 miles / 14 minutes = 2/7 miles per minute
Then, use a common denominator to make calculations easier:
Mai: 1/3 * 7/7
Jada: 2/7 * 3/3
You should get:
Mai: 7/21 miles per minute
Jada: 6/21 miles per minute
By looking at this, you can see that Mai is traveling slightly faster, going more miles than Jada per minute.

x + y = -10 in slope intercept form
Step-by-step explanation:
Hey there!
Given;
x+y= -10
We know that slope intercept equation form of straight line is; y = mx+c.
So, let's try to convert it into that form.
Shift"X" in Right side.
y = -x-10
Therefore, y = -x-10.

FIND VALUE OF X AND OF ANGLE ABC AND ACD
PLS HELP
GEOMETRY
Answer:
see explanation
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ ACD is an exterior angle of the triangle, thus
43 + 5x - 48 = 3x + 57 , that is
5x - 5 = 3x + 57 ( subtract 3x from both sides )
2x - 5 = 57 ( add 5 to both sides )
2x = 62 ( divide both sides by 2 )
x = 31
Thus
∠ ABC = 5x - 48 = 5(31) - 48 = 155 - 48 = 107°
∠ ACD = 3x + 57 = 3(31) + 57 = 93 + 57 = 150°

You need to write an essay that has at least 700 words. You have written 300 words so far. Write an inequality that represents the number of words w that you have left to write.
Answer:
300 + w ≤ 700
Step-by-step explanation:
It would not be 300 + w = 700 because you have to write at least 700 words, so 300 + w must be equal to or greater than 700, and the equal to or greater than sign is ≤

What are the slope and the y-intercept of the linear function that is represented by the equation Y=-10x+1?
a. The slope is -10, and the y-intercept is -1.
b. The slope is -10, and the y-intercept is 1.
c. The slope is -1, and the y-intercept is -10.
d. The slope is 1, and the y-intercept is -10.
Answer:
b. The slope is -10, and the y-intercept is 1.
Step-by-step explanation:
Y = slope(x) + y-intercept
Answer: B) slope = -10, y intercept = 1
The general form is y = mx+b
m = slope
b = y intercept
Comparing y = -10x+1 to y = mx+b we see that
m = -10
b = 1

If f(x) = x2 + 4x + 9. find f(-2)
Answer: f (-2) 5
Your welcome
A function is a relation between two variables where one variable is the set of inputs that gives the other variables as output.
The value of the function at x = -2 is 5.
The domain of the function = 5.
The range of the function = -2.
What is a function?A function is a relation between a set of inputs called domains and it has one output called the range.
Example:
f(x) = x + 2
At x = 2,
f(2) = 2 + 2 = 4
Domain = 2
Range = 4
We have,
f(x) = x² + 4x + 9
We need to find the value of the function at x = -2.
Substitute x = -2 in f(x).
f (-2) = (-2)² + 4x(-2) + 9
f (-2) = 4 - 8 + 9
f (-2) = 5
Thus the value of the function at x = -2 is 5.
