how is computation with the addition of fractions similar and different from whole number computation?​

Some fractions are whole numbers, such as 6/2 or 12/6. But not all fractions are whole numbers, such as 3/4 0r 1 5/8.

The whole numbers are the counting numbers (1,2,3,…) and 0. The fractions are the numbers that can be written in a/b form providing that b is not 0. So you can see that the fractions include the whole numbers.

Also, the fractions are a dense set. In other words there is a fraction between any two fractions. But the whole numbers are not dense. In other words there is no whole number between 2 and 3, for example.

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
