Find the least common multiple which is 24
Answer: 54-7n
Step-by-step explanation:
When we talk about mathematical language, the <u>difference </u>between two numbers, quantities or terms is the <u>substraction operation.</u>
For example, the <u>difference</u> between a and b is:
a-b
On the other hand, if we read a numer c <u>times</u> a number n, this means both numbers are multiplied.
For example:
c <u>times</u> n is:
(c)(n)
So, according to the explained above, “the difference of fifty-four and seven times a number n” is:
54-7n

Answer:
x = 10, y = 13
Step-by-step explanation:
Because EYD is 70, then FEY is also 70. Both triangles are identical.
This means:
45 + 70 + 7x - 5 = 180
7x = 70
x = 10
EFY and EDY are identical and this means:
7x - 5 = 5y
7*10 - 5 = 5y
5y = 65
y = 13
