Her avg is 64 (c).
Answer:
Step-by-step explanation:
Using the values and , the slope is .
So, the equation is:
For 3 it’s b. For 2 it’s 8. For 4 it’s the whole number
Answer:
-10
Step-by-step explanation:
a - b = 7 - (-3) = 7 + 3 = 10
--> | a - b | = 10
--> - | a - b | = -10
Question 1:
First, let's convert both mixed numbers to an improper fraction with a denominator of 8.
4 1/2= 32/8+4/8=36/8
1 7/8= 8/8+7/8= 15/8
Now since the number below the line in the fractions are the same, we can compare them.
Total grapes= 4 1/2 pounds or 36/8 pounds
Red grapes=1 7/8 pounds or 15/8 pounds
Green grapes= ?
To solve for the green grapes, we need to subtract the number of red grapes from the number of total grapes.
36/8=15/8=21/8
Green grapes= 21/8
since 21/8 is an improper fraction, lets convert it to a mixed number
21/8= 2 5/8
Answer: B 2 5/8
Question 2: 5.927 to 5.93
This number was rounded to the nearest hundredths place. We see the number two, was the number being rounded/changed in the action taken. Since the number 2 is in the hundreds place, the answer is C
Answer=C
