Answer:
The distance between A and B is 2.6
Step-by-step explanation:
We know that there are 2 whole numbers from -1 to 0 and 0 to 1. Then we can add the 0.3 from both sides. 0.3 plus 0.3 is 0.6.
I hope this helped and if it did I would appreciate it if you marked me brainliest, thank you and have a nice

Answer:
6
Step-by-step explanation:
The equation for this problem would be c = (20 + 8) / 2 - 8. Add 20 and 8 to get 28, divide 28 by 2 to get 14, then subtract 8 to get 6.
Estimate first. Estimate is basically the same as saying round, so 979 would be rounded to 1,000. 4 x 1,000 = 4,000. 4,000 is the answer. :)

Answer: (4x + 5)/3
Explanation:
D = x
H = x + 5
R = 2x
Mean = (D + H + R)/3
= (x + x + 5 + 2x)/3
= (4x + 5)/2
Answer:
7.5kg
Step-by-step explanation:
Given that:
Monday:
Mass of sand = 24 kg
Mass of cement = 5 kg
Tuesday :
Mass of sand = 36 kg
Let mass of cement = c
Mass of cement required to make the same type of mortar mix
Mass of Sand = mass of cement
24kg = 5kg
36kg = c
By cross multiplication :
24 * c = 5 * 36
24c = 180
Divide both sides by 24
c = 180 / 24
c = 7.5 kg
Hence mass of cement required is 7.5 kg
