4.29 + 97.2 + 0.687 = 102.177
In adding decimal numbers, make sure that the decimal points are aligned. Since each number has different counts of numbers after the decimal point, use 0 to pad the missing places.
4.290
97.200
<u> 0.687
</u> 102.177
The count of numbers after the decimal point is the same count of number of the decimal who has the greatest count of number after the decimal point.
4.29 only has 2 counts of places after the decimal point
97.2 only has 1 count of place after the decimal point
0.687 has 3 counts of places after the decimal point.
The sum of the decimals must also have 3 counts of places after the decimal point.
Step-by-step explanation:
I hope I'm correct. I've never learnt differentiation for log and exponents before
Answer:
Step-by-step explanation:
The sum of 83 and a number would be as an expression, where is "said number".
Answer:
The y-intercept is 2.
Step-by-step explanation:
Assuming that the graph is labelled in increments of 1, the line is crossing the y-axis at 2. That means it's the y-intercept.
I hope this makes sense! ☺
Twice a number decreased by 11 is -23
Let the number be x
So we get the equation
2x -11 = -23
Add 11 to both sides
2x = -12
Divide both sides by 2
x = -6
So the number is -6
Negative 6
