Answer:
42-38
42 + (-38)
-38+42
Step-by-step explanation:
In all of these expressions, the 38 has to be negative because that is what you're taking away from the 48. When you have -(- it turns into a +.
In -42 + 38 the 42 is negative, but that is Emma's total amount so it's positive
With -42 -(-38) they did the just added those two together which would make the 42 still negative and the 38 positive.
THen with 42 + 38 the 38 is being subtracted from what she has so you would not add 38 to her total.
Ratio = 40 : 166 = 20 : 83
Answer: 20 : 83
Answer: D. 36, 108
Step-by-step explanation:
In the geometric series the ratio of two consecutive term is constant and this ratio is called the common ratio,
Let n be the common ratio of the given series,
Then the GP will be,
12, 12×n, 12×n×n, 324,
Again by the definition of Geometric series,

Thus, the required series is,
12, 12×3, 36×3, 324
= 12, 36, 108, 324
⇒ Option D is correct.
First you find 2 points so (-7,-2) and (-9,2) find the slope by starting from the LEFT point and go down so it is equal level to the right point. Once you do that count to the right and get that number to get the slope in this case it is 2/4x or 1/2x no find the y intercept which is where in meets the y axis which is -8 now you have the answer y= 1/2x + -8 make sure to use the formula y= Mx + b to make it easier. Hope this helped!
Answer:
6 minutes
Step-by-step explanation:
20 miles jogs at 1 hour, so for 2 miles,
2/20
= 1/10 hours
