X/(9+11)=4 bc x is the “number” and “9, and 11” means add them together. Put the in parenthesis
The fabric cost $181.875
Step-by-step explanation:
Blue fabric bought = 3 3/4 yards , change to improper fraction (4*3)+3/4 = 15/4 yards
Red fabric= 12 5/6 yards = 77/6 yards
Purple fabric= 7 2/3 yards= 23/3 yards
Find total length of fabric bought, 15/4 +77/6 +23/3 =291/12 yards
Cost per yard= $7.50
Total cost will be, 291/12 * 7.50 =$ 181.875

Answer:
Step-by-step explanation:
Since they are similar we can say
?/15=6/3
?=15(6)/3
?=30
Newton Equations are such as Force = Mass * Acceleration, Potential Energy= mass * acceleration of gravity* height, Force of gravity= universal gravitational constant(Mass of the earth* Mass of Object)/( Distance in between)^2, Kinetic Energy= 1/2Mass (velocity) ^2, Momentum = speed * Mass and Voltage= current * resistance, Energy= Mass * (speed of light)^2 and etc, yet all of these are models for solving physics and mathematics problems.
If a triangle has side lengths 5, 5, and 8, then the triangle should be classified as isosceles.
This is because an isosceles triangle has two sides of the same length and one side of a different length. This isn’t an equilateral triangle (where all sides are of equal length) or a scalene triangle (where all sides are of different lengths).
Hope this helps!
