They would use 8 signs because one mile in this case is broken up into quarters so in a mile it would have 1/4 1/2 3/4 and 1 mile times that by two because they are placing signs for 2 miles so 4+4= 8
Step-by-step explanation:
1) 9x - (-5 + 6x) = 9x + 5 - 6x
Solving like terms
3x + 5
2) 9x - 5 - 6x
3x - 5
3) 9x - 6x + 5
3x + 5
4) 9x - 6x - 5
3x - 5
5) 9x - (-6x + 5)
9x + 6x - 5
15x + 5
2 and 4 are the expressions
Answer:
The answer is B, 3
Step-by-step explanation:
Because if the sum is 10 (x+y=10) and you have to subtract 4 to get the smaller number, 7-4=3 and 7+3=10
Let
x--------> the number of gray bricks
y--------> the number of red bricks
we know that
------> inequality 1
<em>-----> </em>inequality 2
therefore
<u>the answer is</u>
x > 0
0.45x+0.58y≤200
Answer:
12 ≠ 14
Step-by-step explanation:
(4+8)=2+(6x2)
12 = 2 + 12
12 ≠ 14.
So the equation is false.
