Answer:
D
Step-by-step explanation:
75=(4*25)=C
- it means 25*3 which is the new price for the Fifth month should be equal to 75
- <em><u>7</u></em><em><u>5</u></em><em><u> </u></em><em><u>=</u></em><em><u>7</u></em><em><u>5</u></em><em><u>=</u></em><em><u>C</u></em>
Answer:
x = 60
Step-by-step explanation:
Recall: one of the properties of a parallelogram is that consecutive angles are supplementary. This means they add up to given 180°
2x and x are consecutive angles. Therefore:
2x + x = 180
3x = 180
Divide both sides by 3
3x/3 = 180/3
x = 60
Answer:
10a+31 is the simplified version but if you are trying to ask 10a-25=56 your answer would be 8.1
Step-by-step explanation:
Answer:
50
Step-by-step explanation:
42/n³∑k²+12/n²∑k+30/n∑1
=42/n³[n(n+1)(2n+1)/6]+12/n²[n(n+1)/2]+30/n [n]
=7n(n+1)(2n+1)/n³+6n(n+1)/n²+30
=7(n+1)(2n+1)/n²+6(n+1)/n+30
=[7(2n²+3n+1)+6(n²+n)+30n²]/n²
=[14n²+21n+7+6n²+6n+30n²]/n²
=[50n²+27n+7]/n²
=[50+27/n+7/n²]
→50 as n→∞
because 1/n,1/n²→0 as n→∞
