Answer:
D) x² -x - 10 =0
Step-by-step explanation:
Given that
L.C.M
⇒ 
⇒ 9 x + 54 = 9 x² - 36
⇒ 9 x² - 36 - 9x - 54 =0
⇒ 9 x² - 9x - 90 =0
⇒ 9(x² -x - 10 ) =0
⇒ x² -x - 10 =0
Consecutive integers can be represented as x, x+1, x+2 and so on.
x+x+1+x+2+x+3+x+4=-65
5x+10=-65
5x=-75
x=-15
Final answer: -15, -14, -13, -12, -11
Exact form: 89/3
Decimal form:29.666666.....
Mixed number: 29 2/3
Answer: Eleven Fourths xEight Ninths.
Step-by-step explanation: To get the mixed number Eleven Fourths, you have to multiply 4x2 (4 as the denominator and 2 as the whole number) to get 8, and add 3 (numerator) to get 11, and then put 4 over it as the original denominator to get 11/4. Then, just plug back in the numbers: 11/4 x 8/9 (Eleven-Fourths times Eight-Ninths)
