Answer:
< 1 = 88
< 2 = 92
Step-by-step explanation:
First add 4x - 4 + 4x = 180
X = 23
4(23) - 4 = 88
4(23) = 92
A. 39.99
b. 39.99 + 0.25(35) = 48.74
c. 39.99 + 0.25(1) = 40.24
Answer:
So, option A is correct.
Step-by-step explanation:
To find the inverse of the matrix, the formula is:

Inverse of the matrix exists if |A| does not equal to 0
|A| = 7 * 9 -( -2 * -10)
|A| = 63 - 20
|A| = 43
AS |A| ≠ 0
so inverse exist.
now finding Adj A
= ![\left[\begin{array}{cc}9&2\\10&7\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D9%262%5C%5C10%267%5Cend%7Barray%7D%5Cright%5D)
![\left[\begin{array}{cc}9/43&2/43\\10/43&7/43\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D9%2F43%262%2F43%5C%5C10%2F43%267%2F43%5Cend%7Barray%7D%5Cright%5D)
So, option A is correct.
Answer:
9.7*10^9 or 9,700,000,000
Step-by-step explanation:
To find the answer, multiply 9.7 * 10^6 by 1000 times becasue 1kg = 1000g, we got:
9.7 * 10^6 * 1000 = 9.7*10^9 or 9,700,000,000
Hope this help you :3
Answer:
100=x+60
Step-by-step explanation:
Hey There!
So the angle that has a value of 100 is equal to angles x and the angle that is equal to 60
so an equation to solve for x could be
100=x+60
