A glider begins its flight $1\frac{1}{2}$1 1
2 mile above the ground. After 60 minutes, it is 9 tenths$\frac{9}{10}$
9
10 mile above the ground. Find the change in height of the glider. If it continues to descend at this rate, how long does the entire descent last?

a: 1/6, j: 1/4

step-by-step explanation: you are welcome

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.

1st integer x

2nd integer x+1

3rd integer x+2

4th integer x+3

x+x+1 +x+2+x+3 =74

combine like terms

4x+6 = 74

subtract 6 from each side

4x = 68

x = 17

the integers are 17,18,19,20
