Answer:
x = - 4
Step-by-step explanation:
x = 19 is a vertical line parallel to the y- axis
A line parallel to it has the equation
x = c
where c is the value of the x- coordinates the line passes through
The line passes through (- 4, 7 ) with x- coordinate - 4 , then
x = - 4 ← equation of parallel line
The answer to this problem is 'B'.
This is because to find the area of a circle your formula is
A = 3.14•r²
So your first step is
1. Find the radius by dividing the diameter (6) by 2
6/2 = 3 Radius= 3
Now that you have found the radius (3) plug the number in the formula
2. A = 3.14•3²
OR
A = 3.14•3•3
Finally, solve the last step - Find the area
3.14 • 3 • 3 = 28.26
A = 28.26
Answer:
$52.03
Step-by-step explanation:
1. Approach
To solve this problem, first one needs to calculate the sales tax, then one must add that to the amount spent on the purchase. To calculate sales tax, one must convert the percent to decimal form, this can be done by dividing the percent by 100. Then one will multiply the decimal by the amount spent.
2. Find the tax
As states above; to calculate sales tax, one must convert the percent to decimal form, this can be done by dividing the percent by 100. Then one will multiply the decimal by the amount spent.
<u>a. convert percent to decimal</u>
8.4 / 100 = 0.084
<u>b. multiply the decimal by the amount spent</u>
48 * 0.084 = 4.032
The amount spent on sales tax is, $4.032
3. Find the total amount spent
Now all one has to do is add the amount spent in tax by the amount spent on the purchase.
48 + 4.032 = 52.032
Since money is only spent rounded to the second decimal point, one has to round the number;
52.03
You can find additive inverse to find integers and their opposites closed under addition.
