Answer:
6
Step-by-step explanation:
Multiply all three sides by 8 to get x by itself
16/3 < x < 7
5 1/3 < x < 7
so it’s between 5 and 1/3 and 7. the only answer between those two would be 6. 3 and 4 is too less. 5 is also too less.
Answer:
yes your answer is correct
Answer:
(1,0.85)
Step-by-step explanation:
(x,y) = (t,d)
t = 1 minute
d = 0.85 feet
Answer:
Step-by-step explanation:
5p + 9c = p
9c = p - 5p
9c = -4p
c = -4p/9
c= 
5x + y = 9....multiply by 7
10x - 7y = -18
----------------
35x + 7y = 63 (result of multiplying by 7)
10x - 7y = -18
----------------add
45x = 45
x = 45/45
x = 1
5x + y = 9
5(1) + y = 9
5 + y = 9
y = 9 - 5
y = 4
solution is : (1,4)
=========================
-4x + 9y = 9
x - 3y = -6 ....multiply by 4
----------------
-4x + 9y = 9
4x - 12y = -24 (result of multiplying by 4)
---------------add
- 3y = - 15
y = -15/-3
y = 5
x - 3y = -6
x - 3(5) = -6
x - 15 = -6
x = -6 + 15
x = 9
solution is : (9,5)
