Answer:
160
Step-by-step explanation:
there are 24 first class seats. 15% of the total number is 24. that would mean 5% of the total number is 8. 20 times 8 is 160.
Answer:
12537678446.7
Step-by-step explanation:
316+178 divided by 2427 (2639 plus 26383) - 373637/282637
L = A/W
L = 72a³b⁴ / <span>6a²b
L = 12 a b</span>³
3x−2y=12;−3x+8y=−6
Step: Solve3x−2y=12for x:
3x−2y=12
3x−2y+2y=12+2y(Add 2y to both sides)
3x=2y+12
3x

For this case we have the following expression:
6 * 1 = 6
We observe that we have two numbers that multiplied give as a result the value of one of the numbers.
The name of this property is called identity property.
In matrices there is also the identity matrix. It is a matrix whose diagonal is formed by the number one.
Answer:
A property that is illustrated by 6 * 1 = 6 is:
identity
