7.5 feet as a number

90 inches and 2.5 yards

Step-by-step explanation:

There are 12 inches in a foot. Since there are 7.5 feet, you will multiply 7.5 by 12 to get 90 inches.

7.5 x 12 = 90

There are 3 feet in a yard. Divide 7.5 by 3 to find the amount of yards.

7.5 / 3 = 2.5

squares, rhombus, rectangles

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
