Answer:
x/5 =
Step-by-step explanation:
to find this,, you put x / 5 = 20 meaning you need to multiply 20 by 5 to get 100. 100/5 =20
What is the range of f(x) = 3x + 9?
{y | y < 9}
{y | y > 9}
{y | y > 3}
{y | y < 3}
Step-by-step explanation:
there must be some additional information missing (like the domain of the function), because just as it is written here, the function f(x) would not have any limitations, and its range would be -infinity < y < +infinity.
so, it is impossible to tell you which answer option is correct.
because again, based on the given information, none of these options is correct.
Which value of x makes the expressions equal?
9. 3x, x +4
Answer:
2
Step-by-step explanation:
3x = x + 4
2x = 4
x = 2
3x = 6
x + 4 = 6
The value of x will be 0.48 which makes the following expression equal.
What is a mathematical expression?A phrase is considered a mathematical expression if it contains at least two numbers or variables and one or more mathematical operations. Mathematicians can multiply, divide, add, or subtract. An expression is structured as follows: Number/variable, mathematical operator, and expression.
It is given that the expression is, 9.3x = x +4
The value of x is obtained to make the expressions equal.
Apply the arithmetic operation in order to find the value of x.
9.3x = x +4
9.3x-x=4
8.3x=4
x=4/8.3
x=0.48
Thus, the expression below is equivalent since the value of x will be 0.48.

12. A Ford Taurus at Enterprise Rent-a-Car rents for $43.46 per day. You receive 150 free miles per day but are charged $0.25 per mile for any additional miles. How many miles can you drive per day, on average, and not exceed your daily budget of $60.00?
No of extra miles:-
[tex]\\ \tt\hookrightarrow 16.54/0.25=66.16mi[/tex]
Now
Total average miles
[tex]\\ \tt\hookrightarrow 159+66.16=216.16mi/day[/tex]

What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
A Ford Taurus at Enterprise Rent-a-Car rents for $43.46 per day. You receive 150 free miles per day but are charged $0.25 per mile for any additional miles.
Let x be the number of miles that you drive and y be the total rent. Then the equation will be
y = 0.25(x - 150) + 43.46
Then the number of miles that you can drive per day, on average, and not exceed your daily budget of $60.00 will be
60 = 0.25(x - 150) + 43.46
60 = 0.25(x - 150) + 43.46
16.54 = 0.25(x - 150)
66.15 = x - 150
x = 150 + 66.15
x = 216.16 miles
Thus, the number of miles that you can drive per day, on average, and not exceed your daily budget of $60.00 will be 216.16 miles.

Step 1: Solve for x
-5 + x >= -3
x >= 2
Step 2: Graph
Looking at the inequality sign, we can see that it is greater than OR equal to. This means that we will need to use a closed circle to graph.
---Start by placing a closed circle on 2
Then, since x is greater than, the line will continue to the right.
---Closed circle on 2, with a line/arrow continuing to the right

Distibute on left side and add like terms on right.
2x + 6 - 17 = 4x - 7

You are running a concession stand at a basketball game. You are selling hot dogs and sodas. Each hot dog costs $1.50 and each soda costs $0.50. At the end of the night, you made a total of $104.50. You sold a total of 113 hot dogs and sodas combined. You must report the number of hot dogs sold and the number of sodas sold. How many hot dogs were sold and how many sodas were sold?
Answer:
35 hotdogs and 52 sodas sold.
Step-by-step explanation:
x = the number of hotdogs sold, x>0
y = the number of sodas sold, y>0
At the end of the night you made a total of $78.50:
1.50x + 0.50y = 78.50
You sold a total of 87 hotdogs and sodas combined:
x + y = 87
We have the following system of equations:
1.50x + 0.50y = 78.50
x + y = 87
Joyce paid $94.50 for an item at the store that was 55 percent off the original price. What was the original price?
Answer:
$210
Step-by-step explanation:
The original price of the item = 100%
If the item was reduced by 55%, then the discounted price of the item = 100% - 55% = 45%
Therefore, $94.50 = 45% of the original price.
45% = 45/100 as a ratio
Using ratios, and letting [tex]x[/tex] be the original price:
94.50/[tex]x[/tex] = 45/100
Cross multiply: 94.50 x 100 = 45 x [tex]x[/tex]
9450 = 45[tex]x[/tex]
Divide both sides by 45: 210 = [tex]x[/tex]
Therefore, the original price of the item was $210
Alternatively, divide 94.50 by 45 to get the cost per 1%. Then multiply this by 100 to get the original price (100%):
(94.50 ÷ 45) x 100 = 210
