Answer:
Step-by-step explanation:
k = 6x + 100
x = -5
k = 6(-5) + 100
k = -30 + 100
k = 70
Answer:
53 degrees
Step-by-step explanation:
Complementary angles add to 90 degrees
a+b = 90
a=37
37+b = 90
Subtract 37 from each side
37+b-37 = 90-37
b =53
Answer:
a=3
Step-by-step explanation:
Given points (a, b) and (c,d), the midpoint of the points will be at
((a+c)/2, ((b+d)/2)
Therefore, given (9, 2) and (a,2a), our midpoint is at
((9+a)/2, (2+2a)/2) = (6,4)
Matching the x values to their corresponding x values and doing the same with the y values, we get
(9+a)/2 = 6
(2+2a)/2 = 4
First, we have
(9+a)/2 = 6
multiply both sides by 2 to remove the denominator
9+a = 12
subtract 9 from both sides to isolate a
a = 3
2a = 2 * a = 6
Confirming this, we have
(2+2a)/2 = 4
(2+6)/2 = 4
8/2=4
It is already in a decimal
I think you mean percent, so it will be 90%
Sorry if that is not what you mean
Answer:
157.5 square feet
Step-by-step explanation:
If an inch is 3 feet, then
3.5 inches = 10.5 feet (3.5*3)
5 inches = 15 feet (5*3)
The area of a rectangle is length times width so...
10.5*15 = 157.5
