Answer:
The value of x is 15.3.
Step-by-step explanation:
-x / 17 = -0.9
-x = -0.9×17
x = 15.3
Formula for the rectangle area is a * b, In this case we know that:
a * b = 180
a (width) = unknown
b (length) = 1 1/4a
We can write it down as:
a * 1 1/4 * a = 180
a² * 1 1/4 = 180 / ÷ 1 1/4 (both sides)
a² = 144 / square root (both sides)
a = 12
Doublecheck:
a = 12
b = 1 1/4 * 12 = 15
a * b = 12 * 15 = 180 (so it's correct)
Answer: The dimensions of the painting are <u>12 x 15 inches</u>.
Answer: y=4x+11
Step-by-step explanation:
I must assume that your graph is that of a straight line, and that the end points of the line are P and B, and (finally) that T is between P and B. If these assumptions are correct, then the length of the line segment PB connecting points P and B is 15 + 10, or 25.
