Answer:
9 is (2/9) of the way from A = 5 to B = 23.
Step-by-step explanation:
Note that there are 23-5, or 18, units separating 5 and 23.
2/9 of that distance is (2/9)(18), or 4.
Adding 4 to 5, we get 9.
9 is (2/9) of the way from A = 5 to B = 23.
If this is not clear, I'd suggest you draw this situation and prove to yourself that 9 is (2/9) of the way from A = 5 to B = 23.
Answer:
Step-by-step explanation:
3). Naomi walked 4560 m to the nearest 10 m. Peta walked 4600 m to the nearest 100 m.
a). 4555 m ≤ n ≤ 4564 m
4550 m ≤ p ≤ 4649 m
b). If n = 4555 m and p = 4550 m
Then Naomi walked more than Peta
If n = 4555 m and p = 4555 m
Then Both Naomi and Peta walked exactly the same.
If n = 4555 m and p = 4649 m
Then Peta walked further than Naomi.
Therefore, all three statements could be true.
4). (a). x = 120 to nearest 10 → 115 ≤ x ≤ 124
(b). y = 1.24 to 2 decimal places → 1.24
(Already given in 2 decimal places)
(c). z = 0.0124 to 3 significant numbers → 0.0124
Answer:
x=4
Step-by-step explanation:
5x+10=30
Subtract 10 from each side
5x=20
Divided each side by 5
x=4
