The formula for triangle area is b•h/ 1/2. so you would do 12•5=60. then divide that by 2 to get 30
Answer:
$11
Step-by-step explanation:
multiply $2 by four because they charge by hour and not by half hour. = 8
add $3 to 8. =11
Answer:
<em>The number is 46</em>
Step-by-step explanation:
<u>Equations</u>
Suppose:
a = One digit of the number
b = Tens digit of the number
The sum of the digits is 10:
a + b = 10
The number expressed as two-digits quantity is ab, and its value is
10a+b
When we add 18 to that number, we have:
10a+b+18
And that is represented as the number reversed:
10a+b+18=10b+a
Simplifying:
9a+18=9b
Dividing by 9:
a + 2 = b
Substituting in the first equation:
a + a + 2 = 10
2a = 8
a = 4
b = a + 2 = 6
Thus the number is 46
You can take two of the x and y on the table to find the slope:
y2 - y1 / x2 - x1
Lets use (3, 12) and (4, 15)
15 - 12 / 4 - 3
3/1
The slope is 3
Now you can use the point-slope formula to find the equation: y - y1 = m(x - x1)
y - 9 = 3(x - 2)
y - 9 = 3x -6
y = 3x + 3
So you are correct with choice B.
