Answer:
The best estimate for the given calculation is 2.8.
Step-by-step explanation:
To determine the correct option regarding the result of this calculation, the mathematical resolution of the same must be developed:
-14 x 1 /9 x (-2 x 9/10) = X
-14 x 1 / 9 x (-18 / 10) = X
-14 x 1 / 9 x -1.8 = X
-14 / 9 x -1.8 = X
-1.555555 x -1.8 = X
2.8 = X
Therefore, the best estimate result for this mathematical operation is 2.8.
Given: Earning of Arthur in three weeks = $136
Let x be the money he earn in one more week.
If he needs at least $189 to buy the new coat that he wants for school.
Then it gives the inequality
Subtract 136 from both sides of the inequality, we get
Hence, Arthur must earn $ 53 in the next week.
Fraction:5/8. Decimal:0.625. Percentage: 62.5%
Answer:
y=-1/5x+7
Step-by-step explanation:
Write in the form of y=mx+c, - 1/5 as the gradient and the y intercept (when the line meets the y axis) at (0,7)
7( x + 10/7)( x - 3/7) = 0
