Answer:
x = 4.25
Step-by-step explanation:
The given equation of line is :
4(2x-5)+6=-3(-4x+8)-7
Solving LHS,
4(2x-5)+6 = 8x-20+6
= 8x-14
Solving RHS,
-3(-4x+8)-7 = 12x-24-7
= 12x-31
So,
8x-14 = 12x-31
Taking like terms together,
8x-12x = -31+14
-4x = -17
x = 4.25
So, the value of x is equal to 4.25.
Answer:
1. 2A + 3A
2. 2A - B
3. 2A
4. 2(A-B)
Step-by-step explanation:
When multiplying matrix by a number you just multiply each number in the matrix by whatever you are multiplying. When adding 2 matrices you just add the corresponding number in each matrix. Ex: You add the top left number to the top left number. The same goes with subtraction.
< o and < m are congruent because opposite angles are congruent
3t - 15 = 2t + 10
3t - 2t = 10 + 15
t = 25
3t - 15 = 3(25) - 15 = 75 - 15 = 60...< m = 60
< m and < o are consecutive angles and they are supplementary....so they add up to 180
< m + < o = 180
60 + < o = 180
< o = 180 - 60
< o = 120
3s = 120
s = 120/3
s = 40
