Answer:
<u>5x + 6</u>
Step-by-step explanation:
<u>To Do</u>
- Creating an algebraic expression that always results in 6 more than a multiple of 5 if the variable is an integer
<u />
<u>Solution</u>
- Let the variable be x
- Multiple of 5 ⇒ 5x
- 6 more ⇒ +6
- Expression ⇒ <u>5x + 6</u>
360 miles divided by 25 gallons is = 14.4 miles per gallon for Mrs. Walters.
360 miles divided by 32 gallons is = 11.25 miles per gallon for Mr. Walter.
Mrs. Walters gets the better gas mileage of 14.4 mpg.
Answer:
Step-by-step explanation:
Given the equation y = 0.18x, to solve for x, we will make the variable x as the subject of the formula from the equation given.
From the equation y = 0.18x
Divide both sides by the coefficient of x i.e 0.18
y/0.18 = 0.18x/0.18
y/0.18 = x
Hence the function of the variable x = y/0.18
b) Given the amount of the bill as y and x is the tip in dollars.
Given y = $4.95, we are to substitute the value of y = $4.95 into the resulting function in (a) to get x as shown;
Since x = y/0.18
x = $4.95/0.18
x = $27.5
<em>Hence the bill is $27.5</em>
Answer:
x = -5/4, x= -7
Step-by-step explanation:
Using the zero product property to solve this equation,
<u>4x+5 = 0</u>
4x = -5
4x/4 = -5/4
x = -5/4
<u>x+7 = 0</u>
x = -7
Answer:
14h <56
Step-by-step explanation:
The area of a rectangle is given by
A =bh
We know the area is less the 56
bh <56
The base length is 14
14h <56
