Answer:
12x - 6 ≤ - 18
Step-by-step explanation:
We will call "a number" x so
Twelve times a number would be:
12x
Then minus 6
12x - 6
Now we add the less than or equal to sign.
12x - 6 ≤
This is equal to negative eighteen, so:
12x - 6 ≤ - 18
As a bonus we can also solve for x.
12x - 6 = - 18 Add 6 to each side.
12x - 6 + 6 = -18 + 6
12x = -18 + 6
12x = -12 Divide each side by 12
12x/12 = -12/12
x = -12/12
x = -1
So we can say when x ≤ -1 Then 12x - 6 ≤ -18
The answer would be 15
Explanation:
20-x=15
To find ‘x’ subtract the base numbers 20-15=5
And to find ‘3x’ take the answer from the last equation and multiply 3*5=15 so in total your answer would be 15
Answer:
Choose the figure with side lengths 0.5, 1, 2 and 2.5
Step-by-step explanation:
Similar figures are figures which have the same shape but not the same size. This means their angle measures are equal but their side lengths are not instead they are proportional. They are related by a scale factor. To find the new side lengths of the figure multiply the original side lengths by 1/2.
The sides are 1, 2, 4, and 5.
They become:
1*1/2 = 0.5
2*1/2 = 1
4*1/2 = 2
5*1/2 = 2.5
Choose the figure with these distances.

Answer:</h2>
Option: D is the correct answer.
D. 0.45
<h2>
Step-by-step explanation:</h2>
The results of the experiment are given as follows:
Coin Experiment Side of Coin Number of Tosses
Heads 18
Tails 22
This means that total 40 experiments were performed.
( Since 18+22=40)
Also, the number of times head turn up=18
Hence, the experimental probability of getting heads is:
Ratio of number of times head turn up to the total number of experiments performed.
Hence,
Hence, the experimental probability of getting head is:
0.45
