Step-by-step explanation:
45 >= 4x + 5
40 >= 4x
10 >= x (x <= 10)
and
53 > 4x + 5
48 > 4x
12 > x (x < 12)
so, both conditions need to be true (that is the meaning of "and").
how can that be achieved ? well, the harder, narrower condition beats any other.
so, when x <= 10, then it is automatically also smaller than 12.
so, the solution (inequality notation) is
x <= 10
and the graph just shows a line that starts at 10 (with a full, black dot at 10, as the point is included) and goes all the way to the left (to infinity and beyond ...)
Answer:
14.6
Step-by-step explanation:
In the question, we are told that:
Yivgeny's gymnastics scores were 1.5, 1.7, 5.5, and 9.1.
In the question, we are also told that to calculate his total score, we add his top two scores.
Yivgeny's top two gymnastics scores are:
5.5 and 9.1.
Hence, his total scores = 5.5 + 9.1
= 14.6
Yivgeny's total scores = 14.7
Answer:
11/12
Step-by-step explanation:
6 7/12 - 5 2/3
=(6-5) + (7/12 - 2/3)
= 1 + 7/12 - 2*4 / 3*4
= 1 + 7/12 - 8/12
= 1 + 7-8 / 12
= 1 + -1/12
=11/12
We know that:
Container 1: can hold
Container 2: can hold
Container 3: can hold
In total there are
Therefore, the correct answer is 3x.
Answer:
Subtract 8 from both sides to isolate 5n.
23-8= 15
5n=15
divide both sides by 5 to get n.
5n/5= n
15/5=3
n=3
