Take -1-5 first and you'd get -6. then take 5×-6 and you'd get -30. finally take -30-40 and you'd get -70 as your answer
Answer:
<u>94</u>
Step-by-step explanation:
Equating the mean to the scores :
- 88 = 79 + 89 + 90 + x / 4
- 352 = 258 + x
- x = <u>94</u>
Answer:
Let first no. be x
Therefore,
2nd no. is x+1
Third no. is x+2
<em><u>SUM</u></em><em><u> </u></em><em><u>OF</u></em><em><u> </u></em><em><u>NO</u></em><em><u>.</u></em><em><u>'</u></em><em><u>s</u></em><em><u>=</u></em><em><u>x</u></em><em><u>+</u></em><em><u>x</u></em><em><u>+</u></em><em><u>1</u></em><em><u>+</u></em><em><u>x</u></em><em><u>+</u></em><em><u>2</u></em>
<em><u>S</u></em><em><u>=</u></em><em><u>3x</u></em><em><u>+</u></em><em><u>3</u></em>
<em><u>S</u></em><em><u>=</u></em><em><u>3</u></em><em><u>(</u></em><em><u>x</u></em><em><u>+</u></em><em><u>1</u></em><em><u>)</u></em>
